[0047] At the same time, when the first T-shaped seat 17 is fully installed in the first T-shaped slot 11, the first positioning hole 12 corresponds to the second positioning hole 18, so that the positioning column 22 can be embedded in the first positioning hole 12 and the second positioning hole 18, thereby fixing the first T-shaped seat 17 and preventing the first T-shaped seat 17 and the second T-shaped seat 19 from being separated from the first T-shaped slot 11 and the second T-shaped slot 15; when the lining cloth 16 needs to be removed, the positioning column 22 can be taken out from the first positioning hole 12 and the second positioning hole 18;

[0048] At the same time, through the first sponge pad 10 on the transverse plate 9 and the second sponge pad 14 on the inclined plate 13, when the patient's legs are placed on the lining cloth, the first sponge pad 10 and the second sponge pad 14 can protect the transverse plate 9 and the inclined plate 13 through their softness, thereby preventing the patient's legs from directly contacting the transverse plate 9 and the inclined plate 13 and causing pressure sores.

[0049] At the same time, the polyester pad 21 wraps the bottom edge of the lining cloth 16, and the elasticity of the polyester pad 21 prevents the bottom edge of the lining cloth 16 from causing pressure sores on the patient's legs when the patient's legs are placed on the lining cloth 16 for a long time, thereby solving the problem that the bottom edge of the lining cloth easily causes pressure sores on the patient's legs.

[0050] At the same time, the telescopic rod 6 can be moved inside the support rod 4, so that the extension height of the telescopic rod 6 can be adjusted, and the bolt 8 is tightened into the first threaded hole 5 and the second threaded hole 7 to lock and fix the telescopic rod 6; thereby, the height of the entire bone traction frame 1 can be adjusted synchronously, which can be suitable for patients with different needs;

[0051] At the same time, the air permeability of the lining cloth 16 can be improved through the air holes 20, making it more comfortable for patients to use.
