Description

Technical Field

[0001] The utility model belongs to the field of marker pens, and particularly relates to a double-headed marker pen that can be disassembled and used. Background Technique

[0002] A double-headed marker pen is a marker pen with two different colored tips. It is usually used for painting, marking or coloring. Since different colors can be easily switched, one tip of the double-headed marker pen is thinner and suitable for delicate lines and details; the other tip is thicker and suitable for filling large areas of color or marking text. This design allows users to conveniently obtain multiple color options on one pen, improving efficiency and convenience.

[0003] The existing double-headed marker pens are of an integrated design. Therefore, when in use, the marker pen often needs to be continuously flipped to select the required end for coloring. However, in the actual use process, continuously flipping the marker pen for coloring is very prone to errors. And in some cases, it is necessary to separate its two ends for two users to use. Obviously, the existing double-headed marker pens cannot meet this situation, thus affecting the usability of the double-headed marker pen.

[0004] Therefore, in view of the problems that the double-headed marker pen is prone to errors during the coloring process and cannot meet the simultaneous use of two users, a double-headed marker pen that can be disassembled and used is developed. By installing an arc-thread connection structure, a block-type installation structure and a multi-slot disassembly structure on the marker pen, the marker pen can be disassembled up and down, and can meet the use of two people. And when the pen tip is worn, the pen tip can be quickly replaced, thereby improving the usability of the double-headed marker pen and reducing its maintenance cost. Content of the Utility Model

[0030] When working, first, according to the requirements of the drawing needed by the user, the round pen tip 501 and the ax-shaped pen tip 604 can be selected. If the round pen tip 501 is selected, the first storage cover 101 is removed from the outer wall of the first installation cylinder 102. If the ax-shaped pen tip 604 is selected, the second storage cover 404 is removed from the outer wall of the second installation cylinder 403. Then, the drawing work is carried out using the round pen tip 501 or the ax-shaped pen tip 604; when drawing, the first paint tube 105 and the second paint tube 405 can transport the paint to the round pen tip 501 and the ax-shaped pen tip 604 through the first suction tube 504 and the second suction tube 601;

[0031] Next, when it is necessary to disassemble the marker pen for drawing work, hold the first housing 103 with one hand and hold the second housing 401 with the other hand. Then, twist the second housing 401 to drive the threaded column 302 on the second fixing cover 301 to rotate, and take out the threaded column 302 from the inner wall of the threaded cylinder 204, thereby separating the first housing 103 and the second housing 401;

[0032] Then, during use, the round pen tip 501 and the axe-shaped pen tip 604 can be pulled outwards by hand, and the first mounting block 502 and the second mounting block 602 can be removed from the inner walls of the first mounting cylinder 102 and the second mounting cylinder 403 by cooperating with the first limiting groove 503 and the second limiting groove 603, so that the damaged round pen tip 501 and axe-shaped pen tip 604 can be replaced.

[0033] Through the above steps, the use of multiple limiting grooves in cooperation with two mounting blocks enables the user to quickly replace the round pen tip 501 and the axe-shaped pen tip 604. By cooperating the threaded post 302 with the threaded barrel 204, the double-headed marker pen can be separated up and down when needed, allowing it to be used separately for drawing work and ensuring its sealing performance. This solves the problems that it is difficult to separate the two ends of the double-headed marker pen for separate work operations during use and that its pen refill is not convenient for quick replacement.

[0034] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art.
