The invention is used when in use: firstly, the inner slide column 286 is pulled out outwards by an operator, a certain placing space is provided for the grinding piece, then the part of the grinding piece which does not need to be polished is stretched into the shell 281, finally the inner slide column 286 is released, at this time, the pre-clamping of the grinding piece is realized by the elastic force of the spring 285, then the inner threaded sleeve 287 is rotated, the inner threaded sleeve 287 moves downwards along the hollow stud 283 in a spiral manner and extrudes the inner slide column 286 inwards, at this time, the clamping soft head 284 fixedly connected to the bottom end of the inner slide column 286 moves towards the central part inside the shell 281, and at this time, the clamping soft head 284 can realize the clamping and fixing of the grinding piece. Immediately after the grinding member is clamped, the pushing rod 27 is pushed inwards, the sliding plate 23 sleeved with the pushing rod 27 moves inwards along the external rail 25, then the clamping assembly 28 fixedly connected to the top of the sliding plate 23 moves towards the grinding mechanism 4 along with the grinding member, and meanwhile, the connecting frame 22 and the inclined pushing frame 24 fixedly connected to the two sides of the sliding plate 23 also move towards the grinding mechanism 4. As the inclined pushing frame 24 moves, it presses the pressing plate 35, then the pressing plate 35 compresses the return spring 36 with the connecting rod 37 and extends into the dust collecting frame 32, then the other end of the pressing plate 35 presses the ductile plate 38 upwards, at the same time the connecting frame 22 moves towards the grinding mechanism 4 with the inclined plane column 21, at the same time the inclined plane column 21 presses the curved plane pressing rod 343 upwards, then the curved plane pressing rod 343 moves upwards along the inner wall of the conical column 341 and presses the penetrating rod 342, and the other end of the penetrating rod 342 presses the ductile plate 38 outwards, so that the opening surrounded by the top of the ductile plate 38 is enlarged.

When the grinding member moves toward the grinding mechanism 4, the grinding member contacts the grinding head 425 to perform grinding, but when the pressing force between the grinding member and the grinding head 425 is too large, the grinding head 425 moves inward along the gear teeth 424, then the sliding plate 428 connected to the other end of the grinding head 425 is rotated to compress the spring strips 427 and move inward along the folding rods 4304, the ejector rod 439 connected to the other end of the folding rods 4304 moves inward along the circular sleeve 438, and the center sleeve 437 connected to the circular sleeve 438 through the bearing No. three moves inward along the first insert 436, so that the first insert 435 which is originally matched with the second insert 436 in a pressing manner is separated from each other, so that the grinding head 425 stops briefly, and simultaneously, when the second insert 436 fixedly connected to the other side of the center sleeve 437 is embedded into the wide teeth 431, the wide teeth 431 rotate along the center shaft 432 and the grinding head 425.

The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but various modifications can be made by those skilled in the art without inventive effort from the above concepts, and all modifications are within the scope of the present invention.
