[0035] Need to be explained, the number of adjusting plate 22 of the utility model embodiment is two, and symmetrically set, and correspondingly, the number of polishing roller 31 is also two, to polish simultaneously a pair of side edges of mobile phone display screen.

[0036] Further, the adjusting box 21 is provided with a sliding block 25 connected with the adjusting plate 22 through a spring 26. The inner bottom surface of the adjusting box 21 is provided with a sliding rail 211, and the bottom surface of the sliding block 25 is provided with a first sliding groove corresponding to the sliding rail 211. The sliding block 25 is slidable on the sliding rail 211. The first adjusting rod 24 is a screw rod, and the sliding block 25 is provided with a first threaded hole corresponding to the first adjusting rod 24. That is, the first adjusting rod 24 is connected with the adjusting plate 22 through the sliding block 25 and the spring 26. Alternatively, the sliding rail 211 has a T-shaped cross section, and the first sliding groove also has a T-shaped cross section. Due to the cooperation between the sliding rail 211 and the first sliding groove, the sliding block 25 can move on the sliding rail 211 and cannot move in other dimensions. When the first adjusting rod 24 rotates, the external threads of the first adjusting rod 24 and the internal threads of the first threaded hole are matched with each other, so as to drive the sliding block 25 to move on the sliding rail 211. It should be noted that the number of the adjusting plate 22 is two, and the number of the sliding block 25 is also two. The first adjusting rod 24 is a bidirectional screw rod, so as to drive the two sliding blocks 25 to move towards each other or move away from each other. At the same time, when the mobile phone display screen contacts and is polished by the polishing roller 31, the elastic force of the spring 26 can act on the polishing roller 31, so that the display screen and the polishing roller 31 have a buffering effect, thereby avoiding the display screen from being broken due to excessive extrusion when the mobile phone display screen is polished.

[0037] Specifically, when the adjusting plate 22 and the polishing roller 31 are driven by the first adjusting rod 24 to rotate around the rotating shaft, so that the polishing roller 31 is at the first inclination angle, the spring 26 is in a natural state. During the process that the mobile phone display screen moves downward, the display screen gradually approaches the polishing roller 31, and finally a pair of edges of the display screen contacts the polishing roller 31. During the process of continuous contact and polishing, the display screen generates a force on the polishing roller 31. The force acts on the spring 26 through the polishing roller 31 and compresses the spring 26, so as to generate an elastic force.

[0038] Further, the top surface of the adjusting box 21 is provided with a second sliding groove 212, the bottom surface of the support base 23 is provided with a protrusion 27 corresponding to the second sliding groove 212, and the protrusion 27 is connected with a second adjusting rod 28.
