The output ends on both sides of the bidirectional motor 3 are fixedly connected with the winding roller 4, and the surface of the winding roller 4 is provided with the wire rope 2. The setting of the winding roller 4 makes the winding and releasing of the wire rope 2 more orderly, avoids confusion and entanglement, and improves the convenience of use. The end of the wire rope 2 passes around the guide wheel 11 and is connected to the adjustment component 17. The combination design of the first sleeve 7, the second sleeve 8 and the third sleeve 9 allows the lifting device to be flexibly adjusted in length to meet the lifting requirements of different positions.
[0021] Specifically, the adjustment component 17 includes a mounting plate 1701 , and connection blocks 1702 are fixedly connected to the front and rear sides of the upper surface of the mounting plate 1701 , the connection block 1702 is fixedly connected to the end of the wire rope 2 , and a fixing block 1703 is fixedly connected to the middle of the bottom surface of the mounting plate 1701 .
[0022] Specifically, servo motors 1704 are fixedly installed on the front and rear sides of the mounting plate 1701, and the output ends of the two servo motors 1704 are fixedly connected to threaded rods 1705. The ends of the two threaded rods 1705 away from the servo motors 1704 are rotatably connected to the fixed block 1703. The surfaces of the two threaded rods 1705 are threadedly connected to moving blocks 1706, and the bottoms of the two moving blocks 1706 are fixedly connected to hooks 1707. The combination of the servo motors 1704 and the threaded rods 1705 provides a high-precision position adjustment function, which can ensure the accuracy of the center of gravity adjustment during the lifting process.
[0023] Specifically, the adjustment component 17 also includes a suspension rod 1710, and the front and rear sides of the upper end of the suspension rod 1710 are fixedly connected to moving wheels 1709.

A plurality of hooks 1711 are fixedly installed at the bottom of the suspension rod 1710. The design of multiple hooks 1711 enables multiple devices to be hoisted at the same time, thereby improving work efficiency.

[0026] Working principle: When in use, first the first electric push rod 15 pushes the first sleeve 7 to rotate around the first connecting ear 6, so as to adjust the lifting angle, and the second electric push rod 13 pushes the third sleeve 9 to extend from the inside of the second sleeve 8 to adjust the position during lifting. When the center of gravity tilts, the output end of the servo motor 1704 on the tilted side drives the threaded rod 1705 to rotate, so that the moving block 1706 moves. When the moving block 1706 moves toward the side close to the fixed block 1703, the distance between the hook 1707 and the moving wheel 1709 on the tilted side increases. By adjusting the rope 1708, the height of the tilted side is lifted upward to adjust the center of gravity. It can be further known that the servo motors 1704 on both sides can work at the same time to improve the efficiency of the center of gravity adjustment.
