Problems solved by technology

[0002] In teaching, the writing tool chalk that is often used is easy to break due to long-term use, or a short chalk tip is left at the end, which is inconvenient to use and low utilization rate causes waste; because chalk has certain alkalinity, dry It is easy to absorb water and is corrosive to the skin to a certain extent, making the fingers rough to dry. In order to overcome the current technical needs, it is urgent to develop and improve the existing technology

Abstract

The invention provides a chalk writing device. The chalk writing device comprises chalk and a pen body, wherein the pen body is provided with a through hole, a hollow cavity structure is formed in the pen body, an elastic component with a clamp buckle is arranged in the pen body, and the chalk is embedded in the hollow cavity at one end of the pen body. The chalk writing device has the advantages that due to the fact that the chalk is fixed in the pen body to indirectly increase the holding length of the chalk, more convenience is brought to writing. The arrangement of the clamp buckle enables the chalk to be pushed in the pen body conveniently, and the chalk writing device is simple in structure, flexible to operate, and reduces pollution of dust to fingers.

Description

technical field [0001] The invention relates to teaching supplies, in particular to a chalk writing device. Background technique [0002] In teaching, the writing tool chalk that is often used is easy to break due to long-term use, or a short chalk tip is left at the end, which is inconvenient to use and low utilization rate causes waste; because chalk has certain alkalinity, dry It is easy to absorb water and is corrosive to the skin to a certain extent, making the fingers rough to dry.
