[0023] See also Figure 2-3 In order to facilitate the staff to seal the hook 5, the sealing mechanism 6 in this embodiment includes a connecting piece 601 rotatably connected to one end thereof by a compression spring. The connecting piece 601 is toggled to rotate the connecting piece 601. At this time, a large gap is separated between the hook 5 and the connecting piece 601, so that the lifting rope on the object can be put into the inner cavity of the hook 5, and then the connecting piece 601 is released. Due to the setting of the compression spring, the connecting piece 601 can rebound to its original position. The bottom between the opposite sides of the left and right side walls of the inner cavity of the connecting piece 601 is rotatably connected with a threaded rod 602 through a bearing. A driven bevel gear 603 is fixed to the right end of the outer surface of the threaded rod 602. The outer surface of the driven bevel gear 603 is meshed and connected with an active bevel gear 604, which drives the active bevel gear The wheel 604 rotates, and the rotation of the active bevel gear 604 causes the driven bevel gear 603 to rotate, thereby causing the threaded rod 602 to rotate. A sliding rod 605 is fixed to the top between the opposite sides of the left and right side walls of the inner cavity of the connecting piece 601. A movable plate 606 is threadedly connected to the outer surface of the threaded rod 602. A plug rod 607 is fixed to the left side of the movable plate 606. A slot 608 is provided at the top of the right side of the hook 5. The rotation of the threaded rod 602 causes the movable plate 606 threadedly connected thereto to move to the left. At this time, the upper end of the movable plate 606 slides on the outer surface of the sliding rod 605 to limit its movement. The movement of the movable plate 606 drives the plug rod 607 to move, so that the plug rod 607 can enter the inner cavity of the slot 608, thereby sealing the hook 5.

[0024] Among them, a driving rod is fixed to the inner cavity of the active bevel gear 604, the front side of the driving rod passes through the connecting piece 601 and extends to the front side of the connecting piece 601, a through hole is opened at the top of the right side of the movable plate 606, the inner diameter of the through hole is adapted to the outer diameter of the sliding rod 605, the outer diameter of the insertion rod 607 is adapted to the inner diameter of the slot 608, and a fixing hole adapted to the outer diameter of the insertion rod 607 is opened at the top of the connecting piece 601.

[0025] See also Figure 4 In order to stably prevent the fixing frame 4 from swaying, the anti-sway mechanism 7 in this embodiment includes a moving rod 701 fixed to the left and right ends of the upper surface of the fixing frame 4, and the inner cavity of the moving rod 701 is slidably connected with a fixing sleeve 702, and the upper surfaces of the two fixing sleeves 702 are fixed with the same mounting plate 703.

[0026] Among them, the two moving rods 701 are symmetrically distributed at the left and right ends of the vertical central axis of the fixed frame 4, the left side of the mounting plate 703 is fixed to the supporting column 2, and a loosening rope structure is provided in the middle of the lower surface of the mounting plate 703, and the other end of the loosening rope is fixed to the fixed frame 4. The loosening rope structure is started to lift the object, and the rope is wound. Then the moving rod 701 is moved into the inner cavity of the fixing sleeve 702, which can stably prevent the fixing frame 4 from swaying, and then the motor 3 is started. The rotation of the motor 3 can drive the supporting column 2 to rotate, and the angle of the object can be changed.

[0027] It should be noted that the rope loosening and pulling structure is an existing device that can wind and release the rope.

[0028] The working principle of the above embodiment is:

[0029] (1) When the staff hangs the hook 5 on the object to be hoisted, they first move the connecting piece 601 to make the connecting piece 601 rotate. At this time, a large gap is separated between the hook 5 and the connecting piece 601, so that the hoisting rope on the object can be inserted into the inner cavity of the hook 5. Then the connecting piece 601 is loosened. Due to the setting of the compression spring, the connecting piece 601 can rebound to its original position, and the driving rod is rotated to make the active bevel gear 604 rotate. The rotation of the active bevel gear 604 makes the driven bevel gear 603 rotate, and then the threaded rod 602 rotates. The rotation of the threaded rod 602 makes the movable plate 606 threadedly connected thereto move to the left. At this time, the upper end of the movable plate 606 slides on the outer surface of the sliding rod 605 to limit its movement. The movement of the movable plate 606 drives the insertion rod 607 to move, so that the insertion rod 607 can enter the inner cavity of the slot 608, thereby making the hook 5 sealed.

[0030] (2) After the hook 5 is sealed, the rope loosening structure can be activated to lift the object, the rope is wound, and then the moving rod 701 is moved into the inner cavity of the fixing sleeve 702, so that the fixing frame 4 can be stably prevented from swaying and limited, and then the motor 3 is started. The rotation of the motor 3 can drive the support column 2 to rotate, so that the angle of the object can be changed.
