Abstract
The utility model relates to a chalk clip, which comprises a sleeve pipe. The inner diameter of the sleeve pipe is larger than the diameter of a chalk; a plurality of isometric hemispheric rubber bulges are formed on the inner wall of the sleeve pipe by processing; a rubber sleeve is sleeved at an opening of the fixing end of the sleeve pipe; the whole rubber sleeve is a circular truncated cone, and the great circle position thereof is connected with the sleeve pipe; and a corrugated groove is formed on the outer surface of the sleeve pipe by processing. When in use, the chalk is inserted into the sleeve pipe through the rubber sleeve, and due to the pressure of the chalk on the rubber bulges inside the sleeve pipe, the chalk can be tightly located in the sleeve pipe without movement; and during the writing, the sleeve pipe can be held by a user in a manner that the corrugated groove is held by the fingers, and the chalk head extending out of the rubber sleeve can be used for writing, thereby avoiding the direct contact between the hand and the chalk. The utility model has the advantages of simple structure, convenience and practicability, reasonable technique, etc.
Description
