The movement of the clamping block 304 makes it easier for the pressing block 313 to clamp on the surface of the second transmission belt 209, thereby facilitating the fixing of the limiting plate 3 as a whole on the second transmission belt 209. When the brush plate 409 needs to be replaced, the insertion rod 401 is pulled, and the clamping ring 404 squeezes the second spring 405 by pulling the insertion rod 401.
