The patent drives the motor to rotate, drives the grinding disc to rotate, and then drives the servo motor to rotate, drives the grinding disc to move, and grinds the mobile phone shell in the placement slot. At the same time, by changing the height of the grinding disc, the fit between the grinding disc and the mobile phone shell can be changed, and then the mobile phone shell can be polished to different degrees according to actual requirements. All mechanical structures are used, and the operation is simple.

[0004] The above technical solution drives the bidirectional lead screw to rotate by rotating the handle, and then drives the clamping plates to approach each other through the second slider, so as to clamp the mobile phone casing in the groove to prevent the mobile phone casing from moving during the grinding process. However, the device cannot control the clamping force. When the clamping force is too large, the mobile phone casing will be deformed. When the clamping force is too small, the mobile phone casing will shift during grinding, which has poor practicality. Utility Model Content
