The polishing disc 4 is connected to a polishing roller 7 via a threaded hole. A fixing frame 10 is provided at the left end of the base 1, and a hydraulic press 9 is mounted on the fixing frame 10. A telescopic shaft 11 is connected to the right end of the hydraulic press 9, and a telescopic push plate 12 is connected to the right end of the telescopic shaft 11. A bracket 13 is provided in the middle of the base 1. A polishing bushing 8 is placed on the bracket 13; a collection port 14 is provided below the polishing roller 7, a collection pipe 24 is connected to the bottom of the collection port 14, the other end of the collection pipe 24 is connected to the collection box 22, a blower inlet pipe 15 is connected to the upper right side of the collection box 22, a blower 17 is connected to the other end of the blower inlet pipe 15, and a blower outlet pipe 18 is provided at the outlet of the blower 17; a sewage pipe 19 is connected to the bottom of the telescopic push plate 12, and a collection pool 21 is connected to the other end of the sewage pipe 19.

[0023] In this embodiment, the polishing disc 4 is provided with a first threaded hole 5 and a second threaded hole 6.
