An extension shaft 7 is welded to the upper center of the driven gear 8. A drive motor 19 is located below the driving gear 18, and the output shaft of the drive motor 19 is welded to the bottom center of the driving gear 18. An internal cavity 9 is provided inside the rotating column 6, and a hydraulic cylinder 10 is provided inside the internal cavity 9. The piston rod of the hydraulic cylinder 10 passes through and extends to the outside of the rotating column 6. A top frame 11 is welded to one end of the piston rod of the hydraulic cylinder 10. The top frame 11 has an inner groove 12 and a movable guide groove 13 inside. A threaded screw 21 is located inside the movable guide groove 13, and a screw slider 23 is movably mounted on the threaded screw 21. A traction steel cable 24 is hooked onto the pull ring at the lower end of the screw slider 23. An external sleeve 16 is sleeved on the outside of the traction steel cable 24. The external sleeve 16 is welded to the screw slider 23. A lifting hook 17 is hooked onto the lower end of the traction steel cable 24.

[0017] In use, the required items are hoisted using the lifting hook 17. The hydraulic cylinder 10 drives the top frame 11 to move up and down, which in turn drives the lifting hook 17 to move up and down, facilitating the hoisting and lowering of items. The drive motor 19 drives the drive gear 18 to rotate, and the drive gear 18 rotates synchronously with the driven gear 8, which in turn allows the rotating column 6 to rotate and adjust the unloading direction of the hoisting. The servo motor 20 drives the threaded screw 21 to rotate, which in turn drives the screw slider 23 to slide horizontally along the movable guide groove 13, further assisting in the feeding of the hoisted items. During the hoisting process, when the items are hoisted, moved horizontally, and rotated, the external sleeve 16 restricts the swaying of the traction cable 24, thereby ensuring the stability of the items during the hoisting process.

[0018] Please see Figure 4 The lower end of the rotating column 6 is integrally formed with an anti-detachment base 26. The size of the anti-detachment base 26 is larger than the diameter of the central rotating groove 25. The extension shaft 7 is welded to the center position of the anti-detachment base 26. The anti-detachment base 26 integrally formed at the lower end of the rotating column 6 serves to prevent the rotating column 6 from detaching from the bearing plate 2. Please refer to [link / reference]. Figure 3 Horizontal guide rods 22 are provided on both sides of the threaded screw 21. The two ends of the horizontal guide rods 22 are welded to the inner walls of the two ends of the movable guide groove 13, respectively. The screw slider 23 is guided and moved along the movable guide groove 13 via the two horizontal guide rods 22. The horizontal guide rods 22 on both sides of the threaded screw 21 assist the screw slider 23 in guiding its movement along the movable guide groove 13. Please refer to [link / reference]. Figure 3 A servo motor 20 is fixed inside the inner groove 12 by screws. The output shaft of the servo motor 20 is connected to the threaded screw 21 inside the movable guide groove 13 via a coupling. The servo motor 20, fixed inside the inner groove 12 by screws, drives the threaded screw 21 to rotate forward and backward. Please refer to [link / reference]. Figure 1Each of the four ends of the support base 1 is integrally formed with a bracket rod 4, and each of the four bracket rods 4 has a mounting plate 5 welded to its lower end. The bracket rods 4 integrally formed at the four ends of the support base 1 serve to assist in the grounding installation of the support base 1. Please refer to [link / reference]. Figure 1 A top cover plate 14 is provided above the inner groove 12 and the movable guide groove 13. Four connecting rods 15 are provided at the connection position between the top cover plate 14 and the top frame 11. The two ends of the connecting rods 15 are welded to the top cover plate 14 and the top frame 11 respectively. The top cover plate 14 above the inner groove 12 and the movable guide groove 13 serves to shield and protect the inner groove 12 and the movable guide groove 13. Please refer to [link / reference]. Figure 1 Three supporting rods 3 are provided between the bearing plate 2 and the support base 1. The two ends of the supporting rods 3 are welded to the support base 1 and the bearing plate 2 respectively.
