Aiming at solving the shortcomings such as the bad stimulation of the chalk dust on the skin and the wastage of broken chalks during writing, this paper designed an automatic chalk holder with simple structure and good clamping performance in order to solve the problems such as the protection of teacher’s hand skin from the chalk dust while writing on the blackboard and waste problems caused by chalk breaking when chalk is used with different writing strength. The above problems are solved by practical application of the automatic chalk holder.


Chalk, holder design, automatic pen-out, easy to install, protect the skin
