[0035] Working principle: first, when the grinding disc 3 needs to be disassembled, the threaded rod 402 is rotated. Since the threaded rod 402 is in threaded connection with the threaded block 404, and the threaded block 404 is attached to the limiting plate 403, the threaded rod 402 will drive the threaded block 404 to move under the influence of the thread. Since the threaded block 404 is hinged to the first connecting rod 405, and the other end of the first connecting rod 405 is hinged to the fixed block 406, and the fixed block 406 is attached to the guide plate 413, the movement of the threaded block 404 will drive the fixed block 406 to move to the inside of the fixed frame 401 under the action of the first connecting rod 405.

[0036] Secondly, the spring 408 will gradually restore deformation during the movement of the fixed block 406, and the telescopic block 407 is attached to the limiting rod 2 under the action of the spring 408, the movement of the fixed block 406 drives the extrusion block 410 to move, since the extrusion block 410 is hinged with the second connecting rod 409, and the second connecting rod 409 is hinged with the telescopic block 407, therefore, the fixed block 406 is accommodated in the fixed frame 401 initially, the extrusion block 410 is separated from the grinding disc 3 and gradually accommodated in the fixed block 406, when the spring 408 restores the deformation, the movement of the fixed block 406 drives the telescopic block 407 to move and be accommodated in the fixed frame 401, so that the fixing of the grinding disc 3 is released, then the grinding disc 3 is pulled outward to complete the disassembly;

[0037] Finally, when the grinding disc 3 needs to be installed, the hole of the grinding disc 3 is aligned with the limiting rod 2, then pushed to the inside of the grinding frame main body 1, and the limiting rod 2 passes through the hole of the grinding disc 3, then the threaded rod 402 is reversely rotated, the threaded rod 402 drives the threaded block 404 to move, the threaded block 404 drives the fixed block 406 to move and expand, the movement of the fixed block 406 drives the telescopic block 407 to move and attach to the grinding disc 3, after the movement of the telescopic block 407 and the grinding disc 3, the threaded rod 402 is continuously rotated, the fixed block 406 continuously moves to the outside of the fixed frame 401 to make the spring 408 deform, and the movement of the fixed block 406 drives the extrusion block 410 to move and gradually attach to the grinding disc 3, when the extrusion block 410 and the grinding disc 3 are attached, the installation of the grinding disc 3 is completed.
