the third bearing 708 enables the collision avoidance frame 704 to flexibly rotate relative to the bearing seat 901, so that the sweeping disc can better avoid obstacles; the second retainer ring 709 can prevent the third bearing from sliding downwards on the bearing seat; the third check ring 710 can prevent the anti-collision frame 704 from sliding downwards on the third bearing, so that the relative stability of connection between the anti-collision frame and the third bearing is ensured; the third shaft sleeve 711 can realize stable connection between the anti-collision frame 704 and the third bearing 708; the rigid rings 712 and the rigid bars 713 make the entire bumper frame 704 more structurally sound, and the rigid rings also provide a better mounting location for the bumper 705; the buffer member formed by the inflatable tire has better buffer effect; the dust cover 714 can effectively prevent the tiny rope from being wound on the connecting flange 702, the rotation of the driving shaft of the second driving device 701 cannot be influenced, and the problem that the driving shaft cannot rotate directly to cause the second driving device to be damaged does not occur; the second hydraulic motor is mature in technology, low in price and stable in driving; the stopper 210 enables the slider 302 and the guide wheel 305 to move back and forth only in the corresponding first guide groove 204 and second guide groove 505, so as to ensure the working stability of the whole moving mechanism 300.
