Abstract

The utility model relates to a chalk sleeve, which comprises a sleeve body. A sliding block is arranged in the sleeve body, and the front end of the sliding block is provided with a plurality of elastic claws; the two sides of the sleeve body along the length direction are correspondingly provided with chutes, and the two sides of the chutes are provided with a plurality of symmetric grooves; and the sliding block is connected with a pushing rod extending out of the chutes, and the ends of the pushing rod are respectively provided with a pushing cap. When the chalk sleeve is used, a teacher or a student needs not to directly hold a chalk for writing, and the damage caused by direction contact of the chalk with the skin can be avoided. The problem that the chalk can be broken easily is also solved, and the use efficiency of the chalk is increased. The utility model has the advantages that the chalk sleeve has a low cost, is convenient to use and is easy to promote.

Description

Chalk sleeve

Technical field:

The utility model relates to a kind of culture and education apparatus, especially a kind of chalk sleeve that is used to be nested with chalk.

Background technology:

At present, chalk is still the indispensable articles for use of education sector, and numerous teachers and student directly hold chalk with hand and write, and chalk can the adversary cause certain pollution; In addition, chalk in use often fractures into little section, and chalk is also inconvenient with writing after short, have to throw away, and causes certain waste.

Summary of the invention:

The purpose of this utility model provides a kind of chalk sleeve, when the solution people write with chalk, and the problem of chalk adversary's pollution and chalk frangibility.

The purpose of this utility model realizes as follows: this chalk sleeve comprises a body, is provided with slide block in the body, the flexible pawl of the front end of slide block; Body has chute along the both sides correspondence of its length direction, and there are some symmetrical grooves the chute both sides; Be connected with the push rod that extends chute on the slide block, the push rod end is provided with and pushes away cap.

During use, chalk is put into the pen cap, and chalk is fixed by the elastic claw on the slide block, pins with hand and pushes away cap, promote push rod and regulate the position of chalk in the pen cap, push away forward then that chalk stretches out the pen cap, promote the then chalk withdrawal pen cap backward, when the best is adjusted in the chalk extending part, push rod is rotated an angle snap in the groove fixing by pushing away cap, can write, so both directly contact chalk, prevent that again chalk from stretching out too much and fracture without hand.

The utility model in use, teacher and student need not directly hold chalk and write, and prevent that chalk contact skin from causing damage; Also solve the problem of chalk frangibility, improved the service efficiency of chalk.Have characteristics with low cost, easy to use, that be easy to promote.
