[0024] Among them, two first retaining rings 202 are welded on the rotating shaft 201; a protrusion 209 is welded on the top end surface and the bottom end surface of the outer wall of the rotating shaft 201, and the two protrusions 209 are both rectangular block structures, and the protrusion 209 is located between the two first retaining rings 202; A mounting seat 203 is slidably connected to the rotating shaft 201 and the protrusion 209. At this time, the mounting seat 203 cannot rotate axially, and the mounting seat 203 is located between the two first retaining rings 202; six limit rods 204 are installed in a circular array on the right end face of the mounting seat 203, and the six limit rods 204 are all plugged into the fixed holes on the roller 3. At this time, the axial limitation of the roller 3 can be achieved, which is convenient for subsequent detection of the roller 3.

[0025] Among them, an elastic member 206 is sleeved on the rotating shaft 201, and the elastic member 206 is a spiral spring structure; One right end of the elastic member 206 elastically contacts with the left end surface of the mounting seat 203, and one left end of the elastic member 206 elastically contacts with the right end surface of the first retaining ring 202 on the left side; A locking seat 207 is threadedly connected to the rotating shaft 201.

[0032] Among them, a water storage box 501 is installed on the top surface of the protective plate 402, and a water outlet pipe 502 is connected to the water storage box 501. The lower end of the water outlet pipe 502 is located 5 cm above the roller 3. During use, when the water outlet pipe 502 discharges water, the roller 3 can be cleaned.
