When working, in the process of loading and unloading goods, it may be necessary to The goods are loaded and unloaded in different directions by starting the driving motor 13. The output end of the driving motor 13 drives the driving gear 14 to move. Since the driving gear 14 and the driven gear 16 are meshed with each other, the power of the driving motor 13 can be transmitted to the rotating shaft 15 through the cooperation of the driven gear 16. The column 17 rotates with the rotating shaft 15, and the beam 18 also rotates horizontally with the rotation of the column 17.

When the screw rod 20 rotates, the movable block 22 can perform linear motion in the sliding cavity 21 along the direction of the screw rod 20. The linear motion of the movable block 22 can be transmitted to the hydraulic cylinder 25 through the connecting block 23. The hydraulic cylinder 25 drives the fixed clamping assembly to move, thereby adjusting the position of the fixed clamping assembly, thereby improving the efficiency and effect of loading and unloading goods.
[0030] By starting the driving motor 13, the output end of the driving motor 13 drives the driving gear 14 to move. Since the driving gear 14 and the driven gear 16 are meshed with each other, the power of the driving motor 13 can be transmitted to the rotating shaft 15 through the cooperation of the driven gear 16.
