The other side of the outer wall of the ankle clamping bracket 201 is provided with a plurality of second buckles 203 corresponding to the second binding belts 202. A plurality of groups of through holes for the second binding belts 202 to pass through are formed in the inner walls of the two sides of the ankle clamping bracket 201.

[0032] The ankle clamping bracket 201 is made of hard plastic or light alloy material and is in a U shape to ensure sufficient support strength. The second binding belts 202 can be made of a woven belt with small elasticity. One end of the second binding belts 202 is fixed on one side of the outer wall of the ankle clamping bracket 201 by riveting or sewing and is provided with a second buckle 203 on the other side of the outer wall, such as a common gourd-shaped buckle. According to the width and number of the second binding belts 202, corresponding through holes are formed in the inner walls of the two sides of the ankle clamping bracket 201. The second binding belts 202 pass through the through holes and are adjusted and fixed by the second buckles 203. The U-shaped structure can effectively wrap the ankle and provide reliable fixation. The combination of the plurality of second binding belts 202 and the buckles can be accurately adjusted according to the thickness of the ankle of the patient to ensure firm fixation. The through hole design makes the fixation of the binding belt more reasonable, avoids unnecessary compression of the ankle, improves the comfort and stability of wearing, and ensures the realization of the traction effect.

[0033] Further, one end of a connecting member 306 is rotatably connected to the inner walls of the two sides of the Y-shaped connecting member 305. The other end of the two connecting members 306 is fixedly connected to the outer walls of the two sides of the ankle clamping bracket 201.
