A limit block 313 is fixedly connected to the outer wall of the telescopic rod 312. The limit block 313 is used to limit and support the telescopic rod 312. During the rotation of the guide sleeve 301, through the guidance of the first guide groove 203 on the telescopic rod 312, the first cleaning wheel 314 slides on the inner wall of the diversion pipe 202. At the same time, the telescopic rod 312 reciprocates in the inner wall of the third guide groove 302 through the guidance of the third guide groove 302.
