Description

New blackboard is wiped

Technical field

The utility model relates to a kind of teaching aid, and especially a kind of new blackboard is wiped.

Background technology

As everyone knows, blackboard eraser is one of instrument commonly used in the teaching.But the existing and blackboard eraser that once had needs user's wiping repeatedly in use, unusual effort in the use; Stay a large amount of dust in wiping process in the air, the serious threat teachers and students' is healthy; In addition, it is very high that blackboard is all hung mostly, and people of short and small stature just can clip the blackboard eminence by the thing of ascending a height always, extremely inconvenience.For this reason, we provide a kind of new blackboard wiping to be very important.

Summary of the invention
