[0037] like Figure 2 and Figure 3As shown, a chuck 101 is arranged at one end of the support rod 1, and the chuck 101 is used to clamp on the operating table. The support rod 1 is a hollow cylindrical structure, and a thread is arranged on the inner wall of the support rod 1. A threaded rod 102 is arranged inside the support rod 1, and the threaded rod 102 cooperates with the thread inside the support rod 1. The threaded rod 102 can move inside the support rod 1 along the axis of the support rod 1. One end of the threaded rod 102 is connected to a pressing block 103, and the pressing block 103 is placed in the chuck 101. The chuck 10 1 is a C-shaped structure. When in use, the opening of the clamp 101 is directed toward the side of the operating bed, and the movement of the threaded rod 102 drives the pressing block 103 to move, so that the pressing block 103 tightly presses the side of the bed, thereby fixing the support rod 1 on the operating bed. In order to facilitate the rotation of the threaded rod 102, the other end of the threaded rod 102 is connected to the first rotating handle 104, and the threaded rod 102 is set to a hollow structure. The first rotating handle 104 can be placed in the threaded rod 102 after use.

[0038] like Figure 4 As shown, the connecting member 4 includes a first clamping portion 401 and a second clamping portion 402. The first clamping portion 401 and the second clamping portion 402 are in the shape of a clamp and are respectively used to clamp the support rod 1 and the connecting rod 2. The two clamping portions are connected by a threaded sleeve 403 and a screw 404. The screw 404 is arranged in the threaded sleeve 403. The threaded sleeve 403 is provided with an internal thread.

The structure of the connecting rod 2 is as shown in FIG. Figure 6 As shown, the connecting rod 2 is cylindrical as a whole. A third rotating handle 506 is provided on the top of the adapter block 501. By rotating the third rotating handle 506, the conical nut 5011 inside the clamping block 501 moves relatively, thereby squeezing the limiting members 5012 on both sides of the conical nut 5011, so that the limiting members squeeze the spherical structure of the universal joint, thereby fixing the universal joint at a certain position. The internal structure of the universal adapter is not limited to the above structure.

[0041] Furthermore, the other end of the second universal joint 503 is a threaded rod connected to the clamping piece 504, and two clamping jaws 505 are arranged on the clamping piece. The two clamping jaws 505 are arranged opposite to each other for clamping the annular bracket 3. The two clamping jaws 505 are connected by a threaded rod at the end of the second universal joint. A tightening nut 507 is also provided on the threaded rod. By rotating the tightening nut 507, the two clamping jaws 505 are brought closer to each other, so that the annular bracket 3 is fixed on the clamping piece 504.

Specifically, the clamping part 701 is provided with a rectangular opening 7011 that can be clamped on the annular bracket, and the clamping part 701 is provided with a limit block 7012 that cooperates with the arc-shaped rack, and the pull member 6 is rotated and fixed to a certain angle through the cooperation of the limit block 7012 and the arc-shaped rack 7021.

[0044] Furthermore, the fixed part 702 is provided with a rectangular through slot 7022 for the pull rod to pass through and a limit hook 7023, and the limit hook 7023 and the limit slot 6011 on the pull rod cooperate with each other to achieve the condition of the length of the pulling member. When in use, the first button 7013 is pressed, the limit block 7012 slides out from the arc-shaped rack 7021, the fixed part 702 is rotated to a suitable angle, the first button is released, the limit block 7012 is stuck in the arc-shaped rack 7021, and the angle of the pulling member 6 is adjusted; the second button 7024 is pressed, the limit hook 7023 is lifted, and after the pull rod 601 is moved to a suitable position, the second button 7024 is released, and the limit hook 7023 is stuck in the limit slot 6011 of the pull rod to adjust the length of the pulling member 6.

[0045] When in use, first clamp the clamp 101 of the support rod 1 to the side of the operating bed, then rotate the first rotating handle 104 to press the side of the operating bed through the pressing block 103 to fix the support rod 1 on the operating bed; then install the first clamping part 401 of the connecting member 4 on the support rod 1, install the connecting rod 2 on the second clamping part 402 of the connecting member 4, and adjust the position and angle of the support rod 1 and the connecting rod 2.
