In this embodiment, the blocking arm 505 includes two blocking plates 5051 disposed opposite to each other, and a connection block is connected between the middle portions of the two blocking plates 5051. The blocking roller 506 is rotatably disposed between two blocking plates 5051, a rotation passage is formed in the blocking plates 5051 for the rotation lever 501 to pass through, and the blocking plates 5051 are rotated on the rotation lever 501 through the rotation passage. The blocking arm 505 is provided with a second reset element, and the second reset element drives the blocking arm 505 to rotate for reset, and in this embodiment, the second reset element is a torsion spring 509. The torsion spring 509 is disposed between the two blocking plates 5051 and is sleeved on the rotation lever 501. One end of the torsion spring 509 is propped against the lower end of the connecting block, and the other end of the torsion spring 509 is fixedly connected with the front side surface of the cleaning frame 2.
