[0029] The upper end of the support frame 1 is welded with a mounting plate, the mounting plate is threadedly connected with a lifting assembly, specifically, Figure 5As shown, the lifting assembly comprises a sleeve 7, the lower end of the sleeve 7 can be fixedly installed on the mounting plate of the support frame 1 by screwing or welding, both upper and lower ends of the sleeve 7 are embeddedly installed with bearings, and a force transmission cylinder 8 is rotatably installed through the two bearings, the force transmission cylinder 8 is sleeved in the sleeve 7, and the upper and lower ends of the force transmission cylinder 8 are connected with the corresponding bearings respectively, the force transmission cylinder 8 is threadedly connected with a lead screw 9, the force transmission cylinder 8 is sleeved on the lead screw 9 and is threadedly matched with the lead screw 9, the lead screw 9, the force transmission cylinder 8 and the sleeve 7 are coaxial, the two ends of the lead screw 9 extend out of the force transmission cylinder 8, and the upper end of the lead screw 9 is fixedly connected with a mounting seat 2, the mounting seat 2 is hingedly connected with a supporting plate 3 through a hinge block 13, and the supporting plate 3 is used for supporting the wing during wing assembly.

[0030] During the wing assembly process, rotating the force transmission cylinder 8 can drive the lead screw 9 to move up and down, thereby adjusting the height of the supporting plate 13 and the wing, facilitating the assembly of the wing. When the force transmission cylinder 8 rotates forward, the lead screw 9 moves upward, lifting the height of the supporting plate 13 and the wing; when the force transmission cylinder 8 reversely rotates, the lead screw 9 moves downward, lowering the height of the supporting plate 13 and the wing.
