[0028] As one embodiment in the present embodiment, as shown in Figure 2 And Figure 3 As shown, the side of installation shaft 1 close to grinding wheel main part 2 is provided with dismounting and mounting mechanism 3 for dismounting and mounting grinding wheel main part 2, and the dismounting and mounting mechanism 3 includes positioning assembly 4 and limiting assembly 5, the positioning assembly 4 includes baffle 41, the baffle 41 is fixedly sleeved on the surface of installation shaft 1, and a plurality of sets of positioning rods 42 are equidistantly installed on one end of the baffle 41 close to grinding wheel main part 2, a plurality of sets of positioning holes 23 are equidistantly formed on one end of grinding wheel main part 2 close to the side of installation hole 22, each set of positioning rod 42 is inserted in the positioning hole 23, and the structure makes grinding wheel main part 2 slide on the surface of installation shaft 1, and the positioning rod 42 corresponding to a plurality of sets of positioning holes 23 is inserted into the positioning hole 23 until grinding wheel main part 2 moves to abut against the baffle 41, so that grinding wheel main part 2 can be positioned, and the rotation of grinding wheel main part 2 is limited, so that grinding wheel main part 2 can better follow installation shaft 1 to rotate, and the outer diameter of each set of positioning rod 42 is matched with the inner diameter of each set of positioning hole 23, so that grinding wheel main part 2 is more stable and is not prone to shaking.

[0029] As one embodiment in the present embodiment, as shown in Figure 4As shown, the limiting assembly 5 includes two sets of sliding grooves 51, both of which are arranged on the surface of the mounting shaft 1, the inner side of each set of sliding grooves 51 is provided with a spring 52, and the opening of each set of sliding grooves 51 is slidingly provided with a limiting block 53, and the inner end of each set of limiting blocks 53 is connected with the spring 52. This structure allows the two sets of limiting blocks 53 to be pressed at the same time, so that the limiting blocks 53 are pushed into the sliding grooves 51 to compress the springs 52, so that the limiting of the grinding wheel body 2 can be released, and the grinding wheel body 2 can be disassembled, which is simple and convenient, greatly increasing the convenience of the device. The end of each set of limiting blocks 53 close to the grinding wheel body 2 is in contact with the grinding wheel body 2, and the end of each set of limiting blocks 53 away from the grinding wheel body 2 is an inclined surface, so that the grinding wheel body 2 is more convenient to install. By extruding the inclined surface of the limiting block 53, the limiting block 53 can be better pushed into the sliding groove 51 to compress the spring 52, until the grinding wheel body 2 moves to the position between the limiting block 53 and the baffle 41. The limiting block 53 can be pushed out of the sliding groove 51 by the elastic force of the spring 52, so that the limiting block 53 is in contact with the grinding wheel body 2 to limit and fix the grinding wheel body 2 to complete the installation.

[0030] As an embodiment in this embodiment, as shown in Figure 2 and Figure 4 As shown, the side of the mounting shaft 1 close to the limiting assembly 5 is provided with a reinforcing assembly 6 for reinforcing the installation of the grinding wheel body 2.
