The second mounting plate 210 is slidably coupled to the first mounting plate 610 and is slidable in a vertical direction, and the second mounting plate 210 is located below the protection device 600 (i.e., the mounting block 611). The hollow shaft 230 is disposed vertically and rotatably disposed on the second mounting plate 210, and may be connected to the second mounting plate 210 through a bearing. The synchronous belt assembly 220 is disposed on the second mounting plate 210, and an output end (i.e., a driven wheel) of the synchronous belt assembly 220 is connected to the hollow rotating shaft 230 so as to conveniently drive the hollow rotating shaft 230 to rotate. The polishing head 240 is located at the lower end of the hollow rotating shaft 230, and a second liquid outlet communicated with the inner space of the hollow rotating shaft 230 is formed on the polishing surface of the polishing head 240. At this time, it is preferable that the polishing head 240 is a circular sheet, and the circular sheet and the hollow rotating shaft 230 are arranged in an eccentric state, so that a polishing mark generated when the polishing head 240 polishes the screen of the mobile phone is avoided, and the polishing head 240 is made of an existing polishing material. In order to facilitate the abutting of the polishing mechanism 200 and the mounting block 611, the second mounting plate 210 is further provided with an abutting column 211, and the upper end of the abutting column 211 can abut against the pressure sensor (i.e. the bottom of the mounting block 611), so that the stress condition of the mobile phone screen can be conveniently detected. Meanwhile, in order to limit the distance that the polishing mechanism 200 moves on the first mounting plate 610, two limiting portions are arranged on the abutting column 211 at a preset interval in the vertical direction, at this time, a limiting block 712 is preferably arranged on the first mounting plate 610, a through hole is arranged on the limiting block 712, and the limiting block 712 is sleeved on the abutting column 211 through the through hole and is located between the two limiting portions, so that the distance that the polishing mechanism moves on the first mounting plate 610 is limited.

The above is only a part or preferred embodiment of the present invention, and neither the text nor the drawings should limit the scope of the present invention, and all equivalent structural changes made by the present specification and the contents of the drawings or the related technical fields directly/indirectly using the present specification and the drawings are included in the scope of the present invention.
