[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the existing technology, the polishing operation is carried out manually. The operator is close to the polishing wheel for polishing, which is dangerous.

[0015] 3. The dust generated during the polishing process is shielded by the U-shaped enclosure, and the dust generated during the polishing process is absorbed by the dust suction joint, and enters the dust collection box through the connecting air duct and the main air duct, which effectively prevents the dust generated by the polishing operation from polluting the surrounding working environment and affecting the health of the operator.
