[0032] In specific implementation, the first support and the first transmission shaft 31 and the second support and the second transmission shaft 32 are coaxially installed respectively, and are matched by screws and nuts, and at the same time, the studs are screwed to the outer ends of the first transmission shaft 31 and the second transmission shaft 32 respectively, so as to press the first support and the second support, and then realize the assembly of the first roller brush 1 and the second roller brush 1' on the first transmission shaft 31 and the second transmission shaft 32 in a sleeved manner.
