[0002] Smart watches are watches with built-in intelligent systems and smartphone systems that are connected to the Internet to achieve multi-functions. They can synchronize phone calls, text messages, emails, photos, music, etc. with the rapid development of electronic technology. The application areas of smart watches are also expanding. Back shell polishing equipment is used to polish the back shell of watches during the production process of watches. By polishing the back shell of watches, it is convenient for the subsequent assembly of watches, and the appearance of the polished back shell is more beautiful. It is a common production project in the production process of watches.

[0003] Patent application number: CN202020153969.3 discloses a smart watch back cover polishing device, including a chassis, the inner wall of the top of the chassis is threadedly connected with a polishing device, the top of the inner wall of the chassis is fixedly installed with a limit ring A and a limit ring B, the inner parts of the limit ring A and the limit ring B are sleeved with threaded rods, a rotating shaft B is fixedly installed on the inner wall of the rear side of the chassis, the inner walls of the front and rear sides of the chassis are fixedly connected by rotating shaft A and rotating shaft C, a transmission gear A is sleeved on the surface of rotating shaft A, an auxiliary gear is sleeved on the surface of rotating shaft B, a transmission gear B is sleeved on the surface of rotating shaft C, and the threaded rod is meshed with the polishing device, transmission gear A and auxiliary gear at the same time. The watch frame is clamped inside the frame slot, and then the handle is turned to control the threaded rod to rotate.
