At this time, rotating block 22 can not move and rotate along the axial direction of screw rod 29. When the operator rotates screw rod 29, because there is screw thread connection between screw rod 29 and rotating block 22, rotating block 22 will produce linear movement in the axial direction of screw rod 29, and rotating block 22 will approach or away from connecting block 21, when rotating block 22 away from connecting block 21 to a certain degree, first tooth 26 and second tooth 28 will gradually separate.

[0051] Specifically, the working principle of the present application is as follows:
[0052] The shoulder joint traction frame realizes the linear movement and free rotation of the rotating block 22 in the axial direction of the lead screw 29 through the threaded connection between the lead screw 29 and the rotating block 22 and the engagement and disengagement mechanism of the first toothed groove 26 and the second toothed groove 28. When the operator rotates the lead screw 29, the rotating block 22 will move in the axial direction of the lead screw 29, away from or close to the connecting block 21. When the rotating block 22 is away from the connecting block 21 to a certain extent, the first toothed groove 26 and the second toothed groove 28 are disengaged, and the rotating block 22 can freely rotate, thereby providing more flexible traction effect. When the rotating block 22 approaches the connecting block 21, the first toothed groove 26 and the second toothed groove 28 re-engage, and the movement of the rotating block 22 is again constrained.
[0053] The telescopic rod 3 realizes accurate position adjustment through the sliding connection in the first sleeve frame 25 and the threaded connection of the first limiting pin 24. When it is necessary to adjust the position of the telescopic rod 3, the first limiting pin 24 is loosened, and the telescopic rod 3 can freely slide in the first sleeve frame 25.

[0054] The counterweight block 44 is placed on the plate body 41 and can be immediately used when needed without complicated assembly process. This design enables the device to be quickly put into use in emergency situations, improving the response speed of treatment. The modular design of the counterweight mechanism 4 enables the components to be stored and transported separately, reducing space occupation. When needed, the complete counterweight mechanism 4 can be quickly assembled, improving the portability of the device.
[0055] In summary, the present application solves the problem of limited angle adjustment of the traditional shoulder joint traction frame.
