[0031] Working principle:

[0032] First, the worker grasps the handle 18 on the outside of the support frame 23. The handle 18 drives the rotating wheel 22 and pulley 12 at the bottom of the support frame 23 to move. During the movement, goods need to be picked up. The sliding rod 19 is slid to the top by the hydraulic cylinder 17 at the top of the base 16. During the sliding, the sliding rod 19 drives the moving frame 1 to slide to the top. The drive source 7 at the top of the raising plate 6 at the top of the moving frame 1 is activated. The drive source 7 drives the drive gear 8 to rotate. During the rotation, the drive gear 9 rotates, and the driven gear 9 drives the internal central shaft 1. 1. The central shaft 11 rotates, and during the rotation, the connecting seat 13, which is welded and fixed through the connecting block 10, rotates. During the rotation, the fork head 14 is offset. When the offset reaches the required angle, the rotation of the drive source 7 is stopped. At this time, the motor 3 at the top of the reinforcing rib 2 on the outside of the moving frame 1 is started. The motor 3 drives the lead screw 4 to rotate. During the rotation, the lead screw 4 drives the slider 5 to rotate inside the moving frame 1. During the rotation, the central shaft 11 connected to the slider 5 slides synchronously. During the sliding process, the fork head 14 is better connected to the goods.
