An auxiliary teaching device for vocational skill training

Abstract

The invention discloses auxiliary teaching equipment for vocational skill training, and relates to the technical field of auxiliary teaching equipment. It includes an eraser handle, a roller-type eraser pad is installed in the rotation of the eraser handle, a dust collection box is fixed inside the eraser handle, and a dust suction device for reducing chalk dust is arranged in the dust collection box. The device includes a cleaning transmission mechanism, an air suction mechanism and a cleaning mechanism. The mutual cooperation of the roller eraser pad and the powder ash collection box set by the device can realize the special design of the powder ash collection box, which will increase the friction with the contact surface of the roller eraser. , so that the roller-type eraser pad can be used like an ordinary eraser, and the roller-type eraser pad can guarantee automatic cleaning of the roller-type eraser without beating. The way to achieve the cleaning effect, the device can reduce the amount of flying chalk dust in the classroom.

Description

technical field [0001] The invention relates to the technical field of auxiliary teaching equipment, in particular to an auxiliary teaching equipment for vocational skill training.
