Description

The handguard blackboard brush

The utility model relates to a kind of blackboard brush, is a kind of handguard blackboard brush.

At present, vast teacher at school the time employed blackboard brush shown in accompanying drawing 1 of the present utility model.Dust from flying when the most outstanding shortcoming of this blackboard brush erases the board exactly pollutes gesture and facial expression.Though, for solving these shortcomings, blackboard brush has been carried out all innovations, not that too complexity is exactly that practicality is good inadequately, be difficult to be accepted by the teacher.

The purpose of this utility model just provides a kind of simple in structure, and is easily manufactured, can get the blackboard brush of direct handguard effect.

Realize that the technical solution of the utility model is such: the handguard blackboard brush, to wipe core 1 and be embedded in the groove 4 of substrate 2, the face first line of a couplet of substrate 2 is the hand guard glove 3 of an end opening then.Hand guard glove 3 is separable modes with the connecting mode of substrate 2, and promptly hand guard glove 3 can freely take off from substrate 2.The inside edge of substrate recess 4 has a circle raised item 5.The wiping core that is embedded in the substrate recess is that on-fixed is inlayed, and promptly wipes core and can freely take off in groove.

The beneficial effects of the utility model are: add behind the hand guard glove effect of can the adversary playing direct protection, and particularly in the winter time, the most obvious to the hand protection effect that frostbite is arranged; But indirect effect is using water wisely, removes unfavorable and worried that blackboard of every wiping all will wash one's hands from; Hand guard glove can take off independent cleaning, can be repeatedly used; This blackboard eraser is with low cost, is easy to popularize use.

Below in conjunction with accompanying drawing of the present utility model, the specific embodiment of the present utility model is done detailed explanation.
