The thigh support 11, knee support 12 and calf support 13 work together to conform to the shape of the leg raised during walking, so as to increase the support effect on the entire leg.

[0035] The thigh support 11 is provided with a thigh fixing mechanism 2 for binding the thigh, the knee support 12 is provided with a calf fixing mechanism 3 for binding the calf at the bottom, and the knee support 12 is provided with an angle adjustment component 4 for adjusting the angle of the calf fixing mechanism 3 on the side; the calf support 13 is provided with an elastic support mechanism 5 for supporting on the ground at the bottom.

[0036] In this invention, the user binds the thigh of their affected limb to the thigh support 11 via the thigh fixation mechanism 2, and the lower leg to the knee support 12 via the lower leg fixation mechanism 3. The knee bending angle is adjusted to a suitable position via the angle adjustment component 4, so that the user's entire leg is connected to the support 1, achieving a braking effect on the leg. The user's injured leg is supported on the support 1 in a kneeling position, allowing the user to walk normally without additional pressure on the foot, thus providing full protection for the damaged part of the foot and facilitating foot rehabilitation.

[0037] Please see Figure 2 and Figure 4 The thigh fixing mechanism 2 includes a support plate 21 and a first fixing structure 22. The support plate 21 is fixedly installed on the rear side of the thigh support 11. The support plate 21 can be a plastic support or a cloth piece. The front side of the thigh support 11 is also provided with a plurality of first fixing structures 22. The thigh is tightly fixed to the thigh support 11 by the cooperation of the support plate 21 and the first fixing structure 22.

[0038] The lower leg fixation mechanism 3 includes a support plate 31, a rotating shaft 32, and a second fixing structure 33. The two ends of the support plate 31 near the knee bracket 12 are fixedly mounted with rotating shafts 32. The two rotating shafts 32 are rotatably connected to the two sides of the inner wall of the knee bracket 12 through bearings. The rotating shafts 32 are connected to the angle adjustment component 4. The support plate 31 is provided with an arc-shaped groove for supporting the lower leg, and a perforated silicone pad is provided in the arc-shaped groove. Multiple second fixing structures 33 are fixedly mounted on the support plate 31.

[0039] Both the first fixing structure 22 and the second fixing structure 33 adopt a strap structure, which is easy for users to operate and can achieve efficient fixation of limbs.

[0040] Please see Figure 6 Each rotating shaft 32 is connected to an angle adjustment component 4. The angle adjustment component 4 includes a fixed tooth block 41, a movable tooth block 42, a circular plate 43, and a spring 44. The fixed tooth block 41 is fixedly connected to the outer side of the knee support 12. The end of the rotating shaft 32 away from the support plate 31 rotates through the knee support 12, and the fixed tooth block 41 is fixedly sleeved on the outer side of the end of the rotating shaft 32. The end of the rotating shaft 32 extending to the outer side of the knee support 12 is polygonal. The movable tooth block 42 is sleeved on the outer side of the end of the rotating shaft 32 and is limited and slidably connected. The movable tooth block 42 is engaged with the fixed tooth block 41. The circular plate 43 is fixedly connected to the movable tooth block 42. The spring 44 is sleeved on the outer side of the fixed tooth block 41 and the movable tooth block 42. The two ends of the spring 44 are fixedly connected to the knee support 12 and the circular plate 43, respectively.

[0041] The spring 44 is always in a stretched state, and the restoring force of the spring 44 drives the fixed tooth block 41 and the movable tooth block 42 to engage.

[0042] In this invention, pulling the circular plate 43 outward causes the movable toothed block 42 to disengage from the fixed toothed block 41. At this time, the spring 44 is further stretched, and the rotating shaft 32 can rotate freely. The user can then adjust the support plate 31 to a suitable angle. After adjustment, the circular plate 43 is released, and under the reset action of the spring 44, the circular plate 43 drives the movable toothed block 42 to re-engage with the fixed toothed block 41, thereby locking the angle of the support plate 31. This allows the user to easily and quickly change the angle of the lower leg fixing mechanism 3, thereby adjusting the bending angle of the lower leg and avoiding discomfort caused by maintaining the same posture for a long time.

[0043] Please see Figure 2 and Figure 5 The elastic support mechanism 5 includes a support rod 51, pads 52, and an adjustment assembly. The top of the support rod 51 is inserted into the bottom of the calf support 13 and is slidably connected. The pads 52 are fixedly connected to the bottom of the support rod 51. The two pads 52 are connected by a cross plate. The pads 52 can be rubber pads or airbag pads to increase the cushioning effect on the support 1 and improve friction, reducing the possibility of the user slipping. The adjustment assembly is installed at the bottom of the calf support 13.

[0044] Preferably, the adjustment assembly includes adjustment holes 53 and adjustment knobs 54. Multiple adjustment holes 53 are evenly spaced along the length of the support rod 51. The adjustment knob 54 is threadedly connected to the outer bottom of the calf support 13 via a threaded sleeve, and the end of the adjustment knob 54 passes through the side wall of the calf support 13 and can be inserted into the corresponding adjustment hole 53. By controlling the adjustment knob 54 to be inserted and fixed into different adjustment holes 53, the length of the support rod 51 can be adjusted to accommodate users with different leg lengths.
