After stopping the rotation of the screw, start the motor, the motor drives the rotating shaft to rotate, and the rotating shaft drives the grinding disc to rotate, thereby completing the grinding of the alloy part. The purpose of setting the pulley is to reduce the friction between the limit plate and the adjusting plate during the grinding process, thereby increasing the grinding rate.
[0022] In the present application, when the grinding disc needs to be cleaned, the handle is pressed, which will drive the auxiliary plate on its lower surface to be pressed down together. The downward pressure of the auxiliary plate drives the connecting column on its lower surface to slide down along the fixed plate. At the same time, the spring is deformed until the bristles of the cleaning brush touch the grinding disc. The grinder is started. When the grinder is started, it needs to rotate at a low speed to complete the cleaning.

The purpose of providing the handle is to increase the operability and convenience of the cleaning device. Since the handle is U-shaped, the operator can easily hold the handle and more easily control the cleaning force. BRIEF DESCRIPTION OF THE DRAWINGS
