Novel color pen

Abstract

The invention discloses a novel color pen. The novel color pen comprises a pen core, a pen rod and a pen skin, the pen skin is arranged on the outer side of the pen rod, and the pen core is arranged inside the pen rod; the pen core comprises a cylindrical part and connecting parts, the connecting parts are uniformly distributed on the periphery of the cylindrical part, more than three connecting parts are arranged, and the connecting parts and the cylindrical part are integrally formed; the connecting parts adopt bosses or grooves, the bosses each are triangular or dovetail-shaped, the grooveseach are in a trapezoid shape, and the two sides of each trapezoid-shaped groove are straight lines or arcs; and the height of the bosses ranges from 0.3 mm to 1.2 mm, the width of the bosses rangesfrom 0.2 mm to 1.5 mm, the width of the grooves ranges from 0.2 mm to 1. 5 mm, and the depth of the grooves ranges from 0.2 mm to 1.5 mm. According to the novel color pen, the price is low, the environment is protected, the elasticity is good, breakage is not prone to occurrence, writing is smooth, erasing can be carried out, and the use is convenient.

Description

technical field [0001] The invention relates to the field of electric vehicle attachments, more specifically, it relates to a new type of colored pen. Background technique [0002] A pencil is a common writing and drawing tool. The barrel of a traditional pencil is made of wood, and a large amount of high-quality wood is required to manufacture the barrel. A large number of forests have been felled. The speed of felling has exceeded the growth rate of wood, causing serious damage to the environment. [0003] In order to save wood and reduce damage to the environment, researchers are trying to find wood substitutes. Therefore, there have been penholders made of various alternative materials. For example, the paper pen holder, the raw material used in the paper pen holder is still wood, which does not fundamentally solve the problem of waste of resources; for example, the gypsum pen holder, the texture of gypsum is relatively brittle, so such a pen holder is easy to be britt...

AI Technical Summary

Problems solved by technology

For example, the paper pen holder, the raw material used in the paper pen holder is still wood, which does not fundamentally solve the problem of waste of resources; for example, the gypsum pen holder, the texture of gypsum is relatively brittle, so such a pen holder is easy to be brittle, and powder may be generated during use. It is inconvenient to use; for example, plastic pen holder, but plastic is a non-degradable material, which pollutes the environment, and the result of use is not environmentally friendly
