Description

a blackboard eraser

technical field

The utility model relates to a blackboard eraser.

Background technique

After the blackboard eraser of the prior art is used, the dust attached to it is usually patted and removed by hand at will, which will affect the environment and be unhygienic. The dust produced in the pat process not only affects environmental sanitation but also affects the health of users.

Utility model content

The problem to be solved by the utility model is to provide a blackboard eraser which avoids flying dust and protects the environment.

In order to achieve the above object, the technical solution adopted by the utility model is: a kind of blackboard eraser provided includes a blackboard eraser body, the blackboard eraser body is provided with a base, and a rotating shaft is arranged in the length direction of the base, and the rotating shaft is connected to The spring is tightened to drive the rotation shaft to rotate, and the rotation of the rotation shaft drives the vibrating plate.

The base is movably connected with the blackboard eraser body.

The base is a rectangular slot.

With the technical solution of the utility model, after the blackboard eraser is used, one side of the blackboard eraser body is pushed by hand to make it rotate, and the other side is used to wipe the blackboard. Drive the vibrating plate to vibrate to remove dust, then push the blackboard eraser to move, pour the dust in the base into the trash can, and vibrate in a closed way to avoid dust flying, collect dust intensively, and protect the environment.
