Can anyone tell me the specific structural mechanism in the multi color ballpoint pen

When you need to use a refill of a certain color, press it down. There is a protrusion on the inside of the top of each refill, and when one refill is pressed, it gets stuck under the protrusions of the other refills. When the top button is pressed or another refill is pressed, the protrusion is driven downwards because the refill is stuck on an inclined plane.

So when the protrusion goes down, the refill is extruded and the spring springs up the refill.

This is what I just observed through the multi-colored pen, the specific is not easy to describe, LZ can be taken apart to see, look.

The structure of a multi-color ballpoint pen can be broadly divided into two main parts.

The first part is the barrel part, which includes the barrel, the refill, the color core sleeve at the end of the refill, the spring sleeve, the spring, the gasket, and the possible isolation column.

The second part is the refill part, which includes the refill, oil seal, nib, refill head, refill shaft and refill spring.

When the ballpoint pen touches the paper, the battery inside it is powered by electricity, and the current enters the chip from the battery, and the chip reads the required control data from the memory, controls the current from the refill, so that the refill releases particles of different colors, and realizes the writing of different colors of text by drawing the specified color along the straight line on the paper.

Each color core has a corresponding color and is placed in a separate isolator that is isolated from the consumer. Each ballpoint pen has two perforations, one for the color core and one for the refill. The color of each pair of color cores is different, and the cores are taken in order of priority, and finally a variety of colors are written.

Please note that specific construction and components may vary depending on the manufacturer and model. The above description is the basic structure of a common multi-color ballpoint pen.

Push open the blue lid to stop the movement. Press the blue clip to start the movement. The blue and green-red parts are made of plastic elastomeric materials. The yellow straight ink tube is bent by touching parts during assembly. The mechanism is suitable for ballpoint pens.

Summary. Dear, I make the following based on your question. A ballpoint pen is a pen that brings out the writing medium by rolling the ball on the front of the pen or refill.

A ballpoint pen is a pen that uses tiny, rotating balls made of brass, steel, or tungsten carbide to release ink onto the paper as you write. The ballpoint pen is very different from its predecessors – reed pens, quill pens, metal nib pens and fountain pens.

Stable handwriting. The pigment of ballpoint pen ink is dyes, and there are three main ink colors: blue, red and black. Among them, black ink is commonly used in our lives, so now black is the main color, and the ballpoint pen is very wiped off on the book, and now the market is used in the new ink, and the handwriting with it has good durability.

Do you know how ballpoint pens are classified? I'm going to teach you a lot of things
