A 匚 type connecting groove 21 is formed in the middle of one side wall of the hanging basket 2 in a recessed mode longitudinally and inwards, and the end portion of the hydraulic telescopic arm 4 is connected with the hanging basket 2 in a rotating mode through a connecting shaft 5.
The upper leveling cylinder 3 and the lower leveling cylinder 1 are both arranged in the connecting groove 21 and positioned at the front side and the rear side of the hydraulic telescopic arm 4, a first cylinder seat is fixedly connected to the upper side of one side wall of the connecting groove 21, which is far away from the hydraulic telescopic arm 4, a second cylinder seat is fixedly connected to the lower side of the connecting groove, a third cylinder seat is fixedly connected to the front side of the hydraulic telescopic arm 4, a fourth cylinder seat is fixedly connected to the rear side of the hydraulic telescopic arm 4, the cylinder end of the upper leveling cylinder 3 is rotationally connected to the third cylinder seat, the piston rod end of the upper leveling cylinder 3 is rotationally connected to the first cylinder seat, the cylinder end of the lower leveling cylinder 1 is rotationally connected to the fourth cylinder seat, and the piston rod end of the lower leveling cylinder 1 is rotationally connected to the second cylinder seat.

The end part of the hydraulic telescopic arm 4 is of a square pipe structure, and the front side wall and the rear side wall are both rotationally connected with the corresponding side wall on the connecting groove 21 through the connecting shaft 5.
The included angles of the uplink leveling oil cylinder 3 and the downlink leveling oil cylinder 1 with the horizontal plane are different. The arrangement can make the strokes of the upward leveling cylinder 3 and the downward leveling cylinder 1 independent but matched with each other.

The up leveling cylinder 3 and the down leveling cylinder 1 are arranged, so that the dead points of the two cylinders can be at different moments. When one of the cylinders reaches a dead point position, the other cylinder stretches to adjust the hanging basket 2, and after the cylinder passes through the dead point position, the cylinder is controlled to continue to supply oil so as to participate in leveling of the hanging basket 2; when the other side oil cylinder reaches the dead point position, the switching oil cylinder adjusts the hanging basket 2.
When the hydraulic telescopic arm 4 drives the hanging basket 2 to gradually lift to the high position, the upward leveling cylinder 3 gradually stretches, and the hanging basket 2 continuously rotates downwards around the connecting shaft 5 with the hydraulic telescopic arm 4 to be adjusted so as to maintain a relative horizontal state. When the upward leveling cylinder 3 reaches the dead point, the downward leveling cylinder 1 starts to supply oil to control the shrinkage of the downward leveling cylinder, so that the upward leveling cylinder 3 is replaced to adjust the inclination angle of the hanging basket 2, and when the upward leveling cylinder 3 passes through the dead point, the upward leveling cylinder 3 can be continuously supplied with oil to control the elongation of the upward leveling cylinder 3 to adjust the hanging basket 2.
