[0022] The support frame 2 is an L-shaped plate, and the lifting plate 3 is located at the center of four symmetrical support frames 2. The outer side of the lifting plate 3 is slidably connected to the support frame 2. The lifting and lowering of the lifting plate 3 can be limited by the support frame 2 to ensure that the lifting and lowering movement of the lifting plate 3 is stable, and the height adjustment of the clamp 18 is realized. At the same time, the support frame 2 can effectively enhance the stability of the lifting plate 3, and the lifting plate 3 is fixed around to prevent the lifting plate 3 from tilting due to force. The bottom of the sleeve 5 is rotatably connected to the upper surface of the bottom plate 1 through a bearing, and the sleeve 5 is threadedly connected to the outer side of the threaded column 4 through a threaded hole, and the outer side of the sleeve 5 is fixedly connected to the turning handle.

One end of the screw rod 71 is rotatably connected to the inner wall of the lifting plate 3, and one end of the screw rod 71 extends to the outside of the lifting plate 3 and is fixedly connected to the hand wheel. The outer side of the moving block 72 is threadedly connected to the threaded hole on the side of the guide rod 73, the inner wall of the lifting plate 3 is fixedly connected to the two ends of the guide rod 73, the side of the moving block 72 is slidably connected to the guide rod 73 through a circular through hole, the top surface of the moving block 72 is hinged to one end of the connecting rod 8, and the other end of the connecting rod 8 is hinged to the side of the connecting plate 9. By rotating the screw rod 71 to make the moving block 72 move outside the guide rod 73, the connecting rod 1 8 can be driven to rotate the connecting plate 9, so as to adjust the position of the adjusting plate 10 and the clamp 18. Similarly, the adjusting assembly 2 12 can be used to adjust the connecting rod 2 13 to make the adjusting plate 10 and the clamp 18 rotate. Through the coordinated adjustment of the connecting rod 1 8 and the connecting rod 2 13, the position, height and length of the clamp 18 can be adjusted.

By rotating the hand wheel so that the worm 15 drives the worm wheel 17 to rotate, the rotating shaft 16 and the clamp 18 can be driven to rotate synchronously, thereby reducing the difficulty of adjusting the clamp 18 for the staff.

[0023] Working principle: when in use, the staff rotates the sleeve 5 to make the threaded column 4 rise and fall inside the sleeve 5, and uses the support frame 2 to limit and support and improve stability. When the lifting plate 3 is adjusted to the target height, the steel structure is fixed on the clamp 18, and the screw rod 71 is rotated by turning the handwheel at one end of the screw rod 71, and the moving block 72 is further moved under the limiting action of the guide rod 73. The moving block 72 will simultaneously drive the connecting rod 1 8 to move, so that the connecting plate 9 and the adjusting plate 10 can be rotated as a whole about the hinge point at the bottom of the connecting plate 9. Similarly, the adjusting plate 10 can be rotated about the hinge point at the top of the connecting plate 9 through the adjusting component 2 12, which greatly expands the moving range of the clamp 18 and enhances the flexibility of the adjustment of the clamp 18. If the clamp 18 needs to be rotated, the worm 15 can be rotated to drive the worm wheel 17 to rotate, and further the rotating shaft 16 and the clamp 18 are rotated synchronously, so as to realize the rotation of the clamp 18 and the fixed steel structure position.
