During the rotation of the silent wheel 1, the brush 7 remains fixed and contacts the surface of the silent wheel 1. The brush 7 cleans the impurities or silk threads adhered to the surface of the silent wheel 1. The impurities are stuck in the gap of the brush 7 to avoid being stuck inside the silent wheel 1 and affecting the use. When the brush 7 is cleaned regularly, the anti-blocking frame 2 is pulled outward, and the anti-blocking frame 2 drives the brush 7 to move backward. The metal spring 9 at the end of the support rod 8 is stretched, and the gap between the brush 7 and the silent wheel 1 becomes wider, and then the impurities, silk threads, etc. on the brush 7 can be cleaned.
