When the polishing head 13 is in contact with the blade, the staff reverses the No. 1 driving device 8, so that the threaded rod 9 rotates in the opposite direction, so that the threaded rod 9 is separated from the connecting block 11. At the same time, the spring 10 can further push the connecting block 11 to the side away from the threaded rod 9, so that the rebound distance of the connecting block 11 of the polishing head 13 can be increased when the external force acts on it. When the threaded rod 9 needs to be connected to the connecting block 11, the staff starts the electric telescopic rod 7 to connect the threaded rod 9 to the connecting block 11, and when the threaded rod 9 is separated from the connecting block 11, the electric telescopic rod 7 does not retract, and one end of the spring 10 is fixedly connected to the connecting block 11, and the other end is fixedly connected to the telescopic end of the electric telescopic rod 7.

At the same time, the spring 10 can further push the connecting block 11 to the side away from the threaded rod 9, so that the rebound distance of the polishing head 13 can be increased when the external force acts on the connecting block 11. When the threaded rod 9 needs to be connected to the connecting block 11, the staff starts the electric telescopic rod 7 to connect the threaded rod 9 to the connecting block 11.
