At this time, the block 25 can drive the connecting rod 24 to rotate, and the material can be polished by the polishing disc 40.

[0027] When the grinding disc 40 comes into contact with the material, the grinding disc 40 is affected by the reverse thrust, driving the connecting rod 24 to move in the inner cavity of the movable groove 21, thereby providing a certain retreat distance for the grinding disc 40 to prevent the impact generated when the grinding disc 40 comes into contact with the material from damaging the material, thereby improving the safety of the device.

[0028] Among them, the outer ring of the connecting rod 24 is rotatably connected to the bracket 26 through a bearing, and a plurality of push rods 27 are connected to the top of the bracket 26.

[0035] When grinding materials of different heights, the fastening nut 02 included in the first screw group 8 is loosened, and then the fastening bolt 01 is pulled up to adjust the gap between the support plate 9 and the connecting plate 6.

[0036] When the material is placed on the bottom plate 4, the material is located between the two buffer pads 5. The buffer pads 5 can reduce the impact of the device on the material to a certain extent, thereby further avoiding the occurrence of cracks in the material during processing.
