Novel chalk clamp

Abstract

The invention discloses a novel chalk clamp comprising a finger sleeving ring and chalk clamp bodies. The finger sleeving ring is of a circular ring structure. The chalk clamp bodies are arranged on the side face of the finger sleeving ring and each comprise a sleeve and elastic clamping pieces. Each sleeve is of a hollow cylindrical structure with the opened upper face and the opened lower face.The strip-shaped elastic clamping pieces are arranged around the bottom ends of the sleeves. In general, the novel chalk clamp has the advantages of being simple in structure, convenient to use and capable of clamping multiple pieces of chalk simultaneously.

Description

technical field [0001] The invention belongs to the field of stationery and educational supplies, and in particular relates to a novel chalk clip. Background technique [0002] The composition of chalk is a white precipitate of calcium sulfate, which is not easily decomposed, and the particles are larger than dust. It is generally used for writing on blackboards in teaching. Most of the existing chalks are ordinary chalks. When ordinary chalks are used, chalk dust is easier Scattering, the chalk dust pollution in the classroom will be more serious, and when the chalk is about to be used up, the chalk tip is relatively short and difficult to hold, and is usually directly discarded, which is likely to cause material waste; for this, the existing related chalk clips solve the above The problem is that most of the existing chalk holders are single-tube type, which can only hold one piece of chalk at a time, and some classrooms need to use chalks of different colors, which requir...

[0002] The composition of chalk is a white precipitate of calcium sulfate, which is not easily decomposed, and the particles are larger than dust. It is generally used for writing on blackboards in teaching. Most of the existing chalks are ordinary chalks. When ordinary chalks are used, chalk dust is easier Scattering, the chalk dust pollution in the classroom will be more serious, and when the chalk is about to be used up, the chalk tip is relatively short and difficult to hold, and is usually directly discarded, which is likely to cause material waste; for this, the existing related chalk clips solve the above The problem is that the existing chalk holders are mostly single-tube type, which can only hold one piece of chalk at a time, and some classrooms need to use chalks of different colors, which requires multiple chalk holders, which is very inconvenient

[0003] In this regard, a chalk clip device has appeared, comprising a hand-held portion and a chalk clip body. The chalk clip body includes an upper clip body, holes 1 arranged on both sides of the upper clip body, a lower clip body, and Hole 2, block, spring and shaft arranged at the lower part of the lower clip body, the spring is arranged between the upper clip body and the lower clip body, one end is connected with the upper clip body, the other end is connected with the lower clip body, and the shaft body passes through Hole 1, hole 2 and the spring connect the upper clip body and the lower clip body, and the chalk clip is combined with the handle part through the block and the slot; although this structure solves the problem of not being able to hold multiple pieces of chalk, it has the following Disadvantages: First, the direction of the chalk clips is downward, and they are distributed around the hand-held part, so that it is not only inconvenient to write, but also difficult to hold; secondly, the chalk clips use the upper and lower clips The body is connected by a spring to achieve the clamping function. This structure is not easy to adjust the length of the chalk when using it, which is very inconvenient
