Embodiment 1

[0040] Such as figure 1 and figure 2 The shown traction frame for shoulder arthroscopic surgery includes a base and a frame body, the base includes a bottom plate 10, the frame body includes a supporting plate 20, and a telescopic rod 30 is passed between the bottom plate 10 and the supporting plate 20 connected, the telescopic rod 30 includes a fixed sleeve 1 connected to the bottom plate 10 and a moving rod 2 arranged at the lower end of the supporting plate 20, the moving rod 2 is slidably matched with the fixed sleeve 1, and the Both sides of the fixed sleeve 1 are respectively provided with several connecting components, and the moving rod 2 can be connected with the fixed sleeve 1 through a corresponding pair of connecting components, so that the connection between the moving rod 2 and the fixed sleeve 1 can be Reliable connection between them, so that the supporting plate 20 can be reliably connected with the bottom plate 10, and then the frame body can be reliably co...

Embodiment 2

[0050] Such as Figure 6 As shown, on the basis of the first embodiment, the engaging assembly further includes an engaging member 7 arranged on the side wall of the installation hole 21, and the engaging member 7 includes a An annular plate 71, the inner end of the annular plate 71 is provided with an elastic cone 72, the large end of the elastic cone 72 is connected with the inner end of the annular plate 71, and the inner wall of the elastic cone 72 Several annular rubber plates 73 are provided, and an O-shaped rubber ring 74 is arranged on the inner circumference of the annular rubber plate 73, and the O-shaped rubber ring 74 can correspond to the outer circumference of the base rod 53 of the connecting rod 5. The annular groove 531 is snap-connected so as to securely connect the moving rod 2 to the fixed sleeve 1 .

[0051] In this embodiment, the elastic cone 72 is made of rubber.

Embodiment 3

[0053] Such as image 3 and Figure 7 As shown, a first spring 50 is provided between the bottom end of the moving rod 2 and the bottom wall of the inner cavity of the fixed sleeve 1, and one end of the first spring 50 is sleeved on the moving rod 2. On the upper guide column 22 at the bottom end, the other end of the first spring 50 is sleeved on the lower guide column 12 on the bottom wall of the inner cavity of the fixed sleeve 1. Due to the setting of the first spring 50, the telescopic The structure of the rod 30 is more stable.
