[0029] The lifting assembly 301 includes two U-shaped mounting plates 3011, both ends of the U-shaped mounting plates 3011 are located inside the toothed belt 4015, the two U-shaped mounting plates 3011 are fixedly connected by two connecting rods 3012, a mop 3013 is fixedly connected between the two connecting rods 3012, two connecting ropes 3014 are fixedly connected to the top of the two U-shaped mounting plates 3011, and the two connecting ropes 3014 are symmetrically arranged, sockets 3015 are provided on both sides of the two U-shaped mounting plates 3011, and limit blocks 3016 are provided in the sockets 3015, and the distance from the sockets 3015 to the top of the U-shaped mounting plate 3011 is not less than the sum of the thicknesses of the shift plate 4011 and the toothed belt 4015.

[0030] The retractable assembly 302 includes two rotating rods 3021 rotatably connected to the mounting frame 1, the two rotating rods 3021 respectively correspond to the two connecting ropes 3014 and are fixedly connected thereto, and the connecting ropes 3014 are wound around the rotating rods 3021, and one side of the mounting frame 1 is fixedly connected to a No. 1 motor 3022, and the No. 1 motor 3022 is a prior art and will not be described in detail herein. One end of the rotating rod 3021 passes through the mounting frame 1 and is fixedly connected to the output end of the No. 1 motor 3022, and the other ends of the two rotating rods 3021 both pass through the mounting frame 1, and the two rotating rods 3021 are connected through a transmission member 3023, and the transmission member 3023 is composed of two pulleys and a belt.

In this process, the movement of the offset cylinder can be controlled.
