The rotating piece 404 is arranged inside the semicircle block 401 and mechanically connected with the circular card piece 405 and the rectangular roller piece 406. When the clamping unit 400 needs to be applied to the tower, the rotation of the rotating piece 404 will drive the circular card piece 405 and the rectangular roller piece 406 to extend and retract in the front and back directions.

[0045] Reference Figures 1-4 For the second embodiment of the utility model, the embodiment further provides a lifting device. The lifting device comprises a lifting unit 100, a base 101 arranged at the bottom of the lifting unit 100, and a telescopic ladder 102 arranged on the upper surface of the base 101.

[0049] Further, the telescopic ladder 102 comprises a first ladder 102a, a second ladder 102b arranged above the first ladder 102a, a pulley 102c arranged between the first ladder 102a and the second ladder 102b, and an elastic assembly 102d arranged through the center of the pulley 102c.

[0050] It should be noted that the first ladder 102a is fixedly connected to the upper surface of the base 101, the second ladder 102b is connected to the side of the first ladder 102a through the pulley 102c with a groove in the first ladder 102a, and the second ladder 102b can slide up and down through the pulley 102c to reach the required working height, and then the elastic assembly 102d is used to lock the second ladder 102b so that the second ladder 102b cannot be displaced upward and downward.

[0051] Further, the elastic assembly 102d comprises a shell 102d-1, sliding blocks 102d-2 arranged at both ends inside the shell 102d-1, and springs 102d-3 arranged between adjacent two sliding blocks 102d-2.

[0052] It should be noted that the elastic assembly 102d is installed at the center of the pulley 102c and is a concentric shaft with the center of the pulley 102c, the outermost layer of the elastic assembly 102d is the shell 102d-1, which is a cylindrical hollow sleeve, the sliding blocks 102d-2 are installed at both ends of the sleeve, and the sliding blocks 102d-2 are cylindrical and concentric with the sleeve; the springs 102d-3 are installed between the two sliding blocks 102d-2.

[0053] Further, the output assembly 301 is specifically a motor.

[0054] It should be noted that the output assembly 301 is a specific motor, which is a square double-rotor motor, and can rotate clockwise and counterclockwise, and can drive the bevel gear 501 to rotate clockwise or counterclockwise through bidirectional rotation to the output end.

[0055] Further, the fixing assembly 302 includes a fixing plate 302a and fixing blocks 302b arranged at the ends of the fixing plate 302a.

[0056] It should be noted that the fixing plate 302a is rectangular, and is fixedly connected to the first ladder 102a and the second ladder 102b near the tower side, respectively. The fixing blocks 302b are fixedly installed at the ends of the fixing plate 302a, and are rectangular in shape, with one side having a groove, and the groove faces of the two fixing blocks 302b are opposite.

[0057] In use, the operator needs to place the lifting device in front of the required tower, adjust the second ladder 102b to the required height for operation, and fix the second ladder 102b through the elastic assembly 102d. When the required height is reached, the elastic assembly 102d extrudes the two end sliders 102d-2 through the spring 102d-3, and the sliders 102d-2 are popped out and locked through the holes on both sides of the first ladder 102a, so that the second ladder 102b does not slide downward when the operator is working at a high altitude, ensuring the stability of the lifting ladder and the safety of the operator.

[0058] In summary, when the operator uses the lifting device, first place it in front of the target tower, and then open the clamping unit 400 by taking out the plug-in plate 403a in the circular clamping piece 405, so as to put the tower to be clamped. Then, fold the clamping unit 400 and insert the plug-in plate 403a to fix it. Through the rotation of the bevel gear 501 driven by the output assembly 301, the other two gears and the bidirectional threaded rod 502 are driven to rotate, and then the connecting blocks move along the bidirectional threaded rod 502. These connecting blocks are connected to the rotating piece 404 through bolts, and when they move to the left, they will drive the rotating piece 404 and the rectangular roller piece 406 to clamp the tower in the middle, ensuring that the roller 406b tightly fits the tower surface, thereby realizing stable ascending or descending. If it is necessary to fix the clamping mechanism at a certain position, it is only necessary to reverse the rotation of the bidirectional threaded rod 502, so that the circular clamping piece 405 approaches the tower and tightly fits it, while the rectangular roller piece 406 moves away from the tower, thereby increasing the friction force and ensuring the stability of the clamping device.

[0059] Subsequently, the height of the secondary ladder 102b is adjusted to meet the work requirements. The entire process requires the cooperation of the pulley 102c and the elastic assembly 102d. When the secondary ladder 102b reaches the predetermined height, the spring 102d-3 inside the elastic assembly 102d exerts pressure on the sliding blocks 102d-2 at both ends. After being squeezed, the sliding blocks 102d-2 pass through the reserved holes on both sides of the primary ladder 102a and are fixed, thereby ensuring that the secondary ladder 102b does not slide down during the work process. Both the problem of insufficient height of the lifting device and the problem of instability of the lifting device are solved, ensuring the safety of the operator.
