The benefits of a mechanical pen over a pencil are 10

The benefits...

No need to sharpen a pencil.

The handwriting is as fine. There will be no problem with the handwriting being large and small.

Clean. You can choose different thicknesses from the range.

A good mechanical pencil can make you more beautiful and draw straighter lines. The mapping effect is very obvious.

Mechanical pencils can be bought with only lead cores. And pencils always have to be bought.

Environmental protection. Pencils are too wood-intensive.

Although the mechanical pencil is environmentally friendly, however, when the pencil is rounded, you can draw a sense of hierarchy that does not pass, the mechanical pencil is more difficult, I am personally used to using a pencil, but insomnia has the kind of automatic pen that changes the pen head, the pen head is the same as the pencil head, that is both environmentally friendly and effective.

1. You don't have to sharpen a pencil all the time.

2. The handwriting is small, which is conducive to writing in small places (such as between the words and the gaps).

1.No need to sharpen the pencil repeatedly, convenient 2Legible handwriting 3Eco-friendly, wood-saving, low-carbon.

Convenient, economical and beautiful in appearance and beautiful handwriting.

1.Convenient. No need to sharpen a pencil.

2.Environmental protection. No need to cut down trees.

Children are usually not allowed to use mechanical pencils at school, and they only use mechanical pencils to write homework when they get home, because after the ordinary pencil head is bald, if you continue to write the font, it will be very thick, it looks very ugly, and it is very troublesome to plane the pencil.

I think the upstairs are all very good.

How to use a mechanical pencil.

Mechanical pencil Compared with ordinary pencils, his first advantage is that he does not need to sharpen, which is trouble-free. The second is that the refill is thinner in comparison, which is more accurate for drawing, especially design drawing. Let's take a look at how to use mechanical pencils with Baibai Safety Network.

The falling type of the mechanical pencil relies on the gravity of the lead core to automatically produce the lead core. The rotary type conveys the lead core by rotation. Pulsating type (push-to-move type) relies on the pinch to transport the lead core, and the structure has a pinch type, that is, the lead core is pushed once.

The second stroke, the first time to push the nib to extend the barrel, the second time to push the lead core out. The double clamp head type adopts the double clamp head structure, which shortens the distance between the clip head and the end of the pen nib, so that the last remaining 8 15mm residual lead core in the movable pencil can be ejected without a whole lead core, and it can be written continuously. Automatic compensation type (automatic core ejection) can automatically compensate the lead core without rotating or pulsating device, and write continuously.

Mechanical pencil structure.

The pulsating movement structure is the basic structural form commonly used in the movable pencil, which is mainly composed of the barrel, the tip sleeve (nib), the fixed core tube (movable damping), the clamp head (flowering), the locking hoop, the spring, etc.

When the core storage tube is subjected to the action of the pinch pressure (finger pressure), it overcomes the elastic force of the spring and moves downward, and makes the clamp head claw piece open, and at the same time, the lead core relies on its own gravity to leave the original position in the core storage tube, and moves along the core guard pipe wall for a certain length under the control of the damping ring of the braking element. After the pressure is released, the spring returns to its original position, and the lead core is automatically locked and positioned by the locking hoop and the clamp head to complete a pulsating core process. In this way, the core can be continuously pulsated.

Last reminder: When using a mechanical pencil to paint the answer sheet, the strength must be moderate, otherwise it is easy to cause the refill to break, or the answer sheet to be broken, and the force should not be insufficient, otherwise the color will be lighter, resulting in the inability to scan normally, affecting the test results. Also, be sure to contact how to load the refill in advance, otherwise if you are too flustered during the exam, it will also delay a lot of time.

Let's look at the mechanical pencil first, yes or yes, go to the stationery store to buy the corresponding automatic pencil, then align the mouth, and put it in.

1. Zebra anti-breakage MA85

An established mechanical pencil manufacturer, with a low center of gravity, is very stable in writing, and can be said to "write where it is pointed". Finally, the grip should be made of hard glue, and it is not surrounded by other soft or floral processes, and the sweaty hands may be very slippery.

2. Sakura (Sakura) anti-breaking XS-125

The metal nib design, so the center of gravity must be very low, and the grip is still not surrounded by soft materials, so it's okay not to sweat, but it will be slippery if you sweat. In addition, the overall design of the pen barrel is simpler and thinner.

3. Mitsubishi (UNI) mechanical pencil M5-450T

A mechanical pencil with a thick barrel, the design of the automatic core is more humane, mainly to solve the embarrassing situation that one side of the refill is often written on a slippery surface and the other side is not often written, resulting in an unsmooth cross-section of the refill tip. To put it simply, it is able to ensure that the tip of the refill is smooth at all times during the writing process.

4. Dragonfly (Tombow) DPA-132A

Dragonfly's mechanical pencil center of gravity is well controlled, but it is also a low center of gravity, and then the pen clip can control the pen to shake the lead and press the lead, "playability" is relatively high.

5. Pilot shakes the mechanical pencil.

Baile launched a mass-oriented mechanical pencil, after the experience, I don't feel that there is a particularly outstanding place, the overall grip is relatively light, the pen holds a soft rubber non-slip, and the feel is acceptable.

Who is better in pencil compared to mechanical pencil?

Hello pro move pencil to engage <>

Mechanical pencils are also pencils. You're talking about a wooden pencil. When writing, the strokes written by the mechanical pencil will not be too thick, note:

Even if it is a mechanical pencil, it is oblique to hold the pen by quietly holding the pen, so the section of the refill that stretches out after writing a few words will become oblique, and the words written in the large contact area of the bevel will be thick and blurry, and it is best to use the lead core of HB to write a few words and turn the pen. Mitsubishi (UNI) has a kind of Kuru Toga mechanical pencil that can be rotated and the thickness of the characters written is uniform, so it is recommended that you use it. The thickness of the wooden pencil is difficult to control, after all, the lead song core is conical, so the cross-sectional area is larger after wear, and it is always written roughly.

1. Mechanical pencils are easy to break.

Mechanical pencils break easily and are thin. Elementary school students do not grasp the strength well, will always break, coupled with the young age of primary school students, lack of patience, so that the writing is intermittent, will lead to primary school students inattentive, in the long run, slowly develop a small movement more problems.

2. The mechanical pencil lead is thinner.

Mechanical pencil leads are thinner, and some students hold the pen vertically to prevent the refill from breaking. However, when writing vertically, the thumb holding the pen blocks the tip of the pen and affects the line of sight, so you can only write with your head sideways. According to expert research:

Writing with the side head and the unequal visual distance between the two eyes can easily cause visual fatigue and lead to myopia.

Expert advice: It is best for primary school students not to use mechanical pencils or use less mechanical pencils, and instead use wooden pencils with thicker and harder leads.

3. The refill of the mechanical pencil is a bit stiff compared to the pencil and is not suitable for sketching.

The refill of the mechanical pencil is a bit stiff compared to the pencil, and the lines drawn are all the same shape, one color, which is more rigid. A sketchbook is all about using lines to express objects. There are only three colors in the sketch, which are black, white and gray.

Through the light and shade of color, the effect of light and shadow is reflected, making the object more three-dimensional. But the mechanical pencil can't do it, and the thickness of the lines drawn by the mechanical pencil does not change significantly. The shades are too.

Pencil refill is made of carbon sticks, and it is better to rub the drawing paper on the drawing paper, and the lines can be drawn in depth and thickness according to your needs.

4. Compared with pencils, mechanical pencils have sharper nose tips and are easy to hurt.

Compared with pencils, mechanical pencils are too sharp in point, especially for children, because children are not aware of self-maintenance and are prone to accidental injuries.

5. Mechanical pencils are more likely to cause lead poisoning.

Compared with pencils, mechanical pencils have a large part of lead exposure, which can cause excessive exposure to lead in children and adolescents, resulting in lead poisoning.

Which is better mechanical pencil or wooden pencil? Let's find out.

Mechanical pencils and wooden pencils are very good, each has its own advantages, both pencils have their own benefits, if you want to use simple and convenient, it is good to choose a mechanical pencil; When drawing and painting art works, it is more appropriate to use a wooden pencil.

1. Benefits of mechanical pencils.

1) Press and go out, no need to cut, very time-saving and labor-saving.

2) The nib can be retracted into the pen when not in use, so you don't have to worry about being broken.

3) After the lead bar is used up, just stuff in a new lead core, there is no trouble of sharpening pencils with wooden pencils and sawdust.

2. Benefits of wooden pencils.

1) Controllable, it is more comfortable when drawing mathematical graphics or art works, and it can easily draw lines of different thicknesses and depths with the adjustment of the size of the force and the change of the tilt angle with the paper.

2) Compared with mechanical pencils, wooden pencils are usually thicker and not easy to break, and mechanical pencils are easy to break when they are forced.

3) For elementary school students, practicing calligraphy with a wooden pencil is better than a mechanical pencil.

Expansion: Do pencils contain lead

The pencil does not contain lead, the pencil is made of graphite and clay refill and wooden pen barrel, in the ancient Roman period, most of the pencils used by people are pencils, and later found that graphite is easier to write than lead black, and slowly replaced the position of the lead bar, and lead is a heavy metal material, containing a certain toxicity, and the harm to the human body is greater.

Is a low center of gravity mechanical pencil any good

The low center of gravity mechanical pencil is a mechanical pencil that designs the center of gravity of writing on the pen head, which can make the user write more labor-saving, the lead core is not easy to break, and is conducive to stable writing, which is very suitable for professional design and art personnel.

That's all for today's sharing, I hope it can help you.

Abstract:The emergence of the automatic pencil is in line with the needs of people's convenience, it does not need to be rolled, as long as the pencil lead can be used. The thickness of the pencil lead is generally expressed in millimeters, and there are more of them, and they have nothing to do with the softness and hardness of the pencil lead.

China's pencil refill hardness has been divided into 18 levels from the softest 6B to the hardest 10h. Among the eighteen grades, 4B to 2H are writing pencils suitable for general study and office use, among which HB pencils are moderately soft and hard, and they are also used the most.

The hardness and thickness of the mechanical pencil lead have nothing to do with the hardness, and there are various hardnesses, the general ones are HB, the general stationery store covers only sell HB, the larger painting supplies stores will have a variety of hardness of the mechanical pen pencil core, professional painting with a variety of hardness, the box will be written, 2b or 4b, etc., pay attention to it when buying. The pencil lead is thicker than the child's writing strength, so the primary school students use it better, try not to use a very thin refill, if the refill is too thin it will be easy to break, do not use the practice of words.

How to pick the right mechanical pencil.

1. Look at the thickness of the core of the pen potato and plum.

Usually we regard the thickness of the lead as the dividing point, and those that are greater than are thick core pencils and those that are smaller than those are thin core pencils.

There are many types of specifications of fine-core mechanical pencils, and this kind of fine-core mechanical pencils write with relatively slender handwriting and neat visual effects, among which and two are the most common.

There are many types of thick core mechanical pencils, because the refill is thicker, it is usually not suitable for writing, and is mostly used for scribing machine card readers or some special purposes.

2. See the lead way.

1) Push-to-pencil pencil: There will be a button at the top of the mechanical pencil, and when pressed hard, a fixed-length lead core will be pushed out through the mechanical structure inside the mechanical pencil. This method of lead removal is the most common, and its structure is very simple, and it is not easy to damage the lead card when used.

2) Side-pressed pencil: As the name suggests, it is to send out the refill by side pressure, so that the mechanical pencil is provided with a pressure button on the side of the pen barrel to replace the press button at the end of the pen barrel by pressing the mechanism. Since the press mechanism is placed on the side near the grip of the pen, it is more convenient to use.

3) Automatic pencil: This kind of automatic pencil is the latest product, its lead mode does not need to be operated by buttons and other forms, it uses the change of the spring damping ring to push the lead core through the pressure of the pen when writing, and it is sent out with writing.

3. Look at the brand.

The product quality of big brands is often guaranteed, the after-sales service is better, the production technology is mature, the positioning is also reasonable, and the national supervision is relatively strict.
