[0043] When the sanding disc 2 needs to be disassembled and replaced, the motor 710 is first started through the external PLC. The output shaft of the motor 710 rotates to drive the rotating shaft 711 coaxially connected thereto to rotate. The rotating shaft 711 rotates to drive the same-side gear 79 coaxially fixed thereto to rotate. The rotation of the gear 79 drives another gear 79 meshing therewith to rotate. The rotation of the other gear 79 drives the rotating rod 78 coaxially fixed thereto to rotate. The rotation of the rotating rod 78 drives the same-side rotating column 72 coaxially fixed thereto to rotate. The rotation of the rotating column 72 drives the two-way screw rod 73 coaxially fixed thereto to rotate.

Nearly, the connecting plate 74 moves under the guidance of the connecting block 76, the guide block 77 and the guide groove on the inner bottom surface of the installation box 1 on the same side. The movement of the connecting plate 74 drives the two limit rods 75 fixed to it to move. When the limit rods 75 are completely separated from the limit grooves on the outer wall of the plug-in block 4 on the same side, the motor 710 is turned off through the external PLC, and then the sanding disc 2 is pulled upward until the four plug-in blocks 4 are separated from the installation box 1. The disassembly of the sanding disc 2 is completed, and then a new sanding disc 2 is taken, and the bottom of the sanding disc 2 is also pre-installed with four plug-in blocks 4. According to the above, the new sanding disc 2 and the four plug-in blocks 4 can be installed conversely.
