A threaded rod 204 is fixedly connected to one end of the rotating rod 202. A threaded block 205 is threadedly connected to the circumferential surface of the threaded rod 204. A slider 207 is fixedly connected to the side of the threaded block 205. A load-bearing block 208 is provided on the side of the slider 207. The adjustment device 2 includes a snap-fit structure.
[0030] The snap-fit structure includes a positioning block 209, which is fixedly connected to the side of the load-bearing block 208. A snap-fit block 210 is fixedly connected to the side of the positioning block 209. A snap-fit groove 211 is opened on the side of the grinding wheel 203.
