Abstract

The invention discloses a chalk fixer comprising a positioning scale and a fixing block arranged on the positioning scale; a sliding slot arranged at the bottom of the fixing block is arranged on a slider arranged on the positioning scale; a line of first fixing holes for fixing chalks are formed in the side face of the fixing block; and a line of second fixing holes for fixing the chalks are formed in the fixing block. The chalk fixer can be used for more conveniently drawing a line, the efficiency is greatly improved and the line drawing speed is quicker.

Description

technical field [0001] The invention relates to a holder, in particular to a chalk holder. Background technique [0002] Chalk is a tool widely used in daily life and is generally used for writing on blackboards. Ancient chalk was usually made of natural chalk, but nowadays it is replaced by other substances. The composition of chalk is a white precipitate of calcium sulfate, which is not easily decomposed, and the particles are larger than dust. Now, domestic chalk mainly contains two kinds of common chalk and dust-free chalk, and its main component is calcium carbonate (limestone) and calcium sulfate (gypsum), or contains a small amount of calcium oxide. With the existing chalk, the users directly hold the chalk, which is unhygienic, and the line drawing speed is slow and inefficient. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a chalk holder with more convenient line drawi...
