The rack 62 drives the fan gear 61 and the front support plate 4 to rotate, so that the flywheel 8 is turned over to the other side, and the nozzle 3 sprays to the other side of the flywheel 8. When the flywheel 8 is cleaned, the drive motor 67 and the waterproof motor 72 are turned off, and the guide rod 52 is pulled outward to remove the flywheel 8 from the mounting groove of the front support plate 4.

[0026] In summary, the present invention disassembles and assembles the flywheel 8 on the front support plate 4 through the limiting mechanism 5, which is convenient for limiting the flywheel 8, and then cleans the tooth surface of the flywheel 8 through the arc-shaped cleaning brush 71 and the waterproof motor 72 of the tooth surface cleaning mechanism 7, and then the flywheel 8 can be turned over by the flipping mechanism 6, so that the nozzle 3 can clean both sides of the flywheel 8.
