[0051] When people do not need to use the present device, the toothed plate 85 limits the toothed disc 86, the second rotating shaft 63 is also limited, and the first rotating shaft 43 is also limited. If people need to use the present device, they hold the handle 2 with their hands and press the contact plate 82 to move upward. The third return spring 83 is compressed, and the contact plate 82 moves upward to drive the Z-type plate 84 to move upward. The Z-type plate 84 moves upward to drive the toothed plate 85 to move upward. The toothed plate 85 moves upward and disengages from the toothed disc 86, and the first rotating shaft 43 and the second rotating shaft 63 stop being limited. After the burrs at the joint are polished, the contact plate 82 is released. Due to the action of the third return spring 83, the contact plate 82 drives the toothed plate 85 to move downward through the Z-type plate 84. The toothed plate 85 moves downward and contacts the toothed disc 86 for limitation. In this way, the movement of the grinding disc 3 and the wax coating disc 613 can be avoided when the present device is not needed.

[0052] When people grind the joint, the connecting plate 92 keeps the grinding disc 3 and the wax coating disc 613 level, so that the grinding disc 3 and the wax coating disc 613 can be kept level.
