What are the main types of screwdrivers and what are the specifications of screwdrivers?

The types of screwdrivers are:

1. Ordinary screwdriver: It is a screwdriver made together with the head handle, which is easy to prepare, and can be used as long as it is taken out, but because there are many different lengths and thicknesses of screws, sometimes it is necessary to prepare many different screwdrivers.

2. Combined screwdriver: a kind of screwdriver that separates the screwdriver bit and handle, when you want to install different types of screws, you only need to replace the screwdriver bit, and you don't need to bring a large number of screwdrivers. The advantage is that it can save space, but it is easy to lose the screwdriver bit.

3. Electric screwdriver: Electric screwdriver, as the name suggests, is to install and remove screws with electric motors instead of manual ones, usually combination screwdrivers.

4. Clock screwdriver: It belongs to precision screwdriver, which is commonly used in repairing hand-band clocks, so it is called.

5. Small King Kong screwdriver: the head handle and body length are smaller than the commonly used screwdrivers, and they are not clock drivers.

1. Ordinary screwdriver.

It is a screwdriver made of the head handle, which is easy to prepare, and can be used as long as you take it out, but because there are many different lengths and thicknesses of screws, sometimes you need to prepare many different screwdrivers.

2. Combined screwdriver.

A screwdriver that separates the screwdriver bit from the shank, when you want to install different types of screws, you only need to replace the screwdriver bit, and you don't need to bring a large number of screwdrivers. The advantage is that it can save space, but it is easy to lose the screwdriver bit.

3. Electric screwdriver.

Electric screwdrivers, as the name suggests, use electric motors instead of manual installation and removal of screws, usually combination screwdrivers.

4. Clock driver.

It is a precision screwdriver, which is commonly used in repairing hand-band clocks, so it is called.

5. Small King Kong screwdriver.

The head handle and body length are smaller than the commonly used screwdrivers, and are not clock drivers.

In terms of its structural shape, there are usually the following:

1. Straight. This is one of the most common. The head model has a line, cross, rice, T-shaped (plum blossom), H-shaped (hexagonal), etc.

2. L-shaped. It is more common in hexagonal screwdrivers, which use their longer rods to increase the torque, resulting in less effort.

3. T-shaped. There are many applications in the auto repair industry. Screwdriver bit type classification:

Screwdrivers can be divided into a word, a cross, a rice word, a star (computer), a square head, a hexagonal head, a Y-shaped head, etc., among which a word and a cross are the most commonly used in our lives, such as installation, maintenance and so on, it can be said that as long as there are screws, screwdrivers will be used. Hexagon head is not used much, hexagon wrenches are commonly used, like some machines on many screws with hexagon holes, convenient for multi-angle force. The big star type is not seen much, the small star type is often used to disassemble and repair mobile phones, hard disks, notebooks, etc., we call the small screwdriver the clock batch, commonly used star type T6, T8, cross PH0, PH00 and so on.

The header indicates: the word slotted

Cross phillips

Rice word pozi

Star torx

Square-headed square

Hexagonal hexgonal

The screwdriver makes use of the working principle of the lever when it is used to pry the paint cover. The greater the distance from the power point to the fulcrum, the more labor-saving, so the long cone is more labor-saving than the short taper.

pH0: screwdriver bit diameter about 3 0 mm, for screws of m1 6 m2;

PH1: Screwdriver bit diameter about 5 0mm, for screws of DAOM2 M3;

PH2: screwdriver bit diameter about 6 5 mm, for screws of m3 5 m5;

PH3: Screwdriver bit diameter about 8mm, (for extra-large Phillips screws).

A screwdriver is a common tool used to twist a limb screw to get it in place, usually with a thin wedge-shaped head that can be inserted into the groove or notch of the screw head.

Beijing-Tianjin-Hebei, Jin, Shaanxi, northern Shaanxi and northern Henan dialects are called "change cone", northern Henan is more called screwdriver loss Bi accompaniment, Jiangxi, Anhui, and Hubei, Henan, south of the Yellow River, Shaanxi Guanzhong is called "screwdriver", and the central and western regions are called "change the knife".

There are mainly two kinds of pins (negative sign) and cross (positive sign). There are also common hex screwdrivers, including hexagon and hexagon sockets.

There are mainly the following types of screwdrivers: Slotted screwdrivers; Phillips screwdriver; square screwdriver; star screwdriver; Mi-shaped screwdriver; hexagon head screwdriver; Y-head screwdriver.

Among them, slotted screwdrivers and Phillips screwdrivers are always available at home, which can be easily installed and removed.

What problems should be paid attention to when using a screwdriver:

1. In the process of daily maintenance of the screwdriver, it is necessary to grind the blade of the screwdriver, so that the two sides of the blade can be kept in a parallel state, so that it will be more convenient to use in the later stage. If you find that the blade of the screwdriver has become tapered, you should not continue to use it, and sharpen it in time to prevent the blade from slipping out of the screw opening.

2. When grinding the head of the screwdriver, you need to pay special attention to polishing it into a parallel state, and you must not polish it too thin, otherwise it will affect the later use. Moreover, the screwdriver head generally needs to be sharpened into a square shape, so it is necessary to avoid grinding it into other shapes, so as not to bring greater trouble when using.

3. If the screwdriver is polished on the grinding wheel, then special caution should be taken to ensure personal safety. After all, during the operation of the grinding wheel, a large amount of heat will be generated, so as to achieve the effect of softening the edge of the screwdriver. Therefore, individuals need to wear goggles to protect their eyes from damage.
