A connecting rod 712 is fixedly connected to the bottom of the sliding block 79. The end of the connecting rod 712 away from the sliding block 79 is fixedly connected to a leveling plate 713.

[0027] A push rod 4 is fixedly connected to the top of the base 1. The design of the push rod 4 is beneficial to facilitating the staff to control the movement track of the electric wheel 2.

[0028] The side cross-section of the push rod 4 is T-shaped. The gear 714 meshes with the rack 710. The side cross-section of the sliding block 79 is T-shaped. The belt 74 is drivingly connected to the circumferential surface of the transmission cylinder B77.

[0029] A re-pressing device 8 is arranged on the front side of the leveling plate 713. The re-pressing device 8 includes a square block 81. A torsion spring rod 82 is rotatably connected to the side of the square block 81. A sleeve 83 is fixedly connected to the circumferential surface of the torsion spring rod 82.

[0033] A specific application of this embodiment is as follows: First, the staff member holds the push rod 4 fixed to the top of the base 1 and starts the electric wheel 2 fixed to the bottom of the base 1. Then, the staff member starts the motor 71 fixed to the top of the shock-absorbing plate 3, driving the rotation of the rotating shaft 72 fixed to the output shaft, so that the transmission cylinder A 73 fixed to the circumferential surface of the rotating shaft 72 rotates. When the transmission cylinder A 73 rotates, it drives the movement of the belt 74 on the circumferential surface, so that the transmission cylinder B 77 fixed to the circumferential surface of the rotating rod 76 rotates, and at the same time drives the rotation of the rotating rod 76 passing through the side surface of the connecting plate 75. When the rotating rod 76 rotates, it drives the rotation of the gear 714 fixed to the circumferential surface, driving the movement of the rack 710 meshing with the gear 714, thereby driving the sliding block 79 sliding on the inner wall of the hollow plate 78 to move downward, squeezing the spring 711 fixed to the bottom of the inner wall of the hollow plate 78 to be in a tense state. At the same time, when the sliding block 79 moves downward, it drives the leveling plate 713 fixed to the bottom of the connecting rod 712 to move downward to perform secondary leveling on the leveled ground. Subsequently, when the gear 714 is no longer meshed with the rack 710, the spring 711 drives the sliding block 79 to reset, so that the leveling plate 713 no longer levels the ground. Finally, when the leveling plate 713 moves downward, it drives the square block 81 fixed to the front side to move downward, making the leveling wheel 85 rotating on the side surface of the cross plate 84 contact the ground. When the leveling wheel 85 contacts the ground, the torsion spring rod 82 rotating on the side surface of the square block 81 rotates, driving the sleeve 83 fixed to the circumferential surface to rotate, and at the same time making the leveling wheel 85 rotate to remove impurities on the ground.
