Preferably, a fixed limiting ring and a movable limiting ring are respectively arranged at two ends of the polishing disc on the shaft body of the motor, and the movable limiting ring is in threaded connection with the shaft body.

Preferably, a cover body is further sleeved on the shaft body between the polishing disc and the fixed limiting ring, and the bottom edge of the cover body does not protrude out of the lower surface of the polishing disc.

Preferably, the hand-held portion is formed with a depression matching a palm grip.

According to the technical scheme, the end of the rack is set to be the handheld portion, the end of the rack is set to be the polishing portion, the motor bearing frame is arranged below the polishing portion, the motor is installed in the motor bearing frame, the shaft body of the motor is sleeved with the polishing disc, a telescopic rod and a second telescopic rod are respectively arranged at the front end position and the rear end position of the motor between the polishing disc and the polishing portion to adjust the inclination angle of the motor bearing frame, the inclination angle of the motor bearing frame is adjusted through the telescopic rod and the second telescopic rod, the inclination angle of the polishing disc is adjusted, and polishing of dead corners can be more flexible through change of the inclination angle.

Additional features and advantages of the invention will be set forth in the detailed description which follows.
