Abstract

The invention discloses a chalk holder. The chalk holder comprises a hollow clamp body of which the right end is closed and the left end is opened, a removable rubber jacket sleeves the exterior of the clamp body, an outer spring for enabling the rubber jacket to reset through left shifting is arranged between the rubber jacket and the clamp body, an inner spring fixed at the closed end is arranged inside the inner chamber of the clamp body, and elastic clips used for clamping pieces of chalks are uniformly arranged at the left end of the clamp body in the circumferential direction. The chalk holder provided by the invention can achieve chalk handling and chalk length control functions conveniently without requiring a handle part to be in contact with the chalk, the friction between the handle part and the chalk holder can be reduced due to the rubber jacket, and the chalk holder is more convenient to hold.

Description

technical field [0001] The invention relates to teaching classroom utensils, in particular to a chalk cover for holding chalk. Background technique [0002] At present, metal or hard plastic is generally used as the material of the chalk case that is widely used, and the chalk is put into the chalk case by manual operation; and the input productivity and utilization rate of the chalk box are not high, so that the chalk can only be stored in the original box. In a paper box. [0003] Because the chalks are closely arranged in the chalk case, it is necessary to touch the chalks by hand to extract the chalks from the chalk case. Unavoidably, the same problem is encountered when manually loading and unloading the chalks into and out of the chalk case. Long-term contact between hands and chalk will undoubtedly cause great damage to the skin, and the high quality of ordinary chalk sets will inevitably cause teachers to write inconveniently and affect classroom teaching.
