[0043] Firstly, the rotation of the driving motor 310 drives the rotation of the threaded rotating rod 320. When the threaded rotating rod 320 and the movable block 560 are connected through threads, the movable block 560 is conveyed forward. In order to avoid the synchronous rotation of the movable block 560 under the rotation of the threaded rotating rod 320, the rotation of the movable block 560 is limited by the positioning sleeve block 510 and the bent sliding rod 370, and the force in the rotation direction is converted into the force for forward pushing. Therefore, the movable block 560 slides in the left-right direction of the threaded rotating rod 320. When the threaded rotating rod 320 drives the positioning sleeve block 510 to move, it also drives the conveying table 540 to slide. During the sliding of the conveying table 540, the bent sliding rod 370 and the sliding block 520 are also in a sliding state.

The movement of the upper and lower groups of conveying tables 540 is kept synchronous, that is, the foot pedal element 530 is clamped when the conveying tables 540 move close to each other. After clamping, the foot pedal element 530 is pushed forward under the continuous rotation of the threaded rotating rod 320. One side of the foot pedal element 530 is polished when it contacts the polishing roller 160, and the other side of the foot pedal element 530 is polished again when it passes through the removing assembly 4. At the same time, both sides can be polished. The foot pedal element 530 placed on the upper end of the conveying table 540 can be clamped and continuously conveyed forward.
