Multiple longitudinal fixing straps 3 and transverse fixing straps 5 are arranged on the upper part of the thigh fixing strap 1, and multiple longitudinal fixing straps 4 and transverse fixing straps 5 are arranged on the upper part of the calf fixing strap 9. The longitudinal fixing strap 3 and the longitudinal fixing strap 4 are connected by a buckle 6, and the head and tail ends of the transverse fixing strap 5 are connected by a buckle 6. A winding mechanism 7 is arranged at one end of both the longitudinal fixing strap 3 and the transverse fixing strap 5.
[0020] In this embodiment, the winding mechanism 7 includes a release component, a housing 701, a knob 704, a shaft rod 705, a ratchet wheel 706 and a pawl 707. The front and rear ends of the shaft rod 705 are rotatably connected to the middle parts of the front and rear ends of the housing 701. The rear end of the shaft rod 705 penetrates through the middle part of the rear end of the housing 701 and is fixedly connected to the middle part of the knob 704. The middle part of the ratchet wheel 706 is fixedly connected to the front end of the shaft rod 705. One end of the pawl 707 is connected to the inner side wall of the front part of the housing 701 through a torsion spring, and the other end of the pawl 707 meshes with the outer periphery of the ratchet wheel 706. A release component is arranged on the front part of the housing 701, and the release component is connected to the end of the pawl 707 close to the ratchet wheel 706. Limit baffle plates 708 are arranged at both the front and rear ends of the shaft rod 705. The release component includes a chute 702 and a lever 703. The chute 702 is opened on the upper side of the front part of the housing 701, and the outer periphery of the lever 703 is slidably connected to the inside of the chute 702. The rear end of the lever 703 is fixedly connected to the end of the pawl 707 close to the ratchet wheel 706.
[0021] Specifically, first connect the thigh fixing strap 1 and the calf fixing strap 9 together through the buckle 6 and fix them on the patient's leg. Then rotate the knob 704 to make the shaft rod 705 wind up the longitudinal fixing strap 3 or the transverse fixing strap 5, so that its length becomes shorter. The ratchet wheel 706 and the pawl 707 can prevent the shaft rod 705 from reversing due to pulling, ensuring that the longitudinal fixing strap 3, the longitudinal fixing strap 4 and the transverse fixing strap 5 can firmly fix the thigh fixing strap 1 and the calf fixing strap 9 on the patient's leg and prevent loosening.
[0022] In this embodiment, a lining component 2 is arranged at the lower part of the thigh fixing strap 1 and the calf fixing strap 9 through a magic tape. The lining component 2 is provided with a number of through ventilation holes. The lining component 2 includes a breathable cloth 201, a breathable sponge 202 and an anti-slip silica gel 203.
