[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0017] Embodiment

[0018] Please refer to Figure 1 and Figure 2 As shown, the thigh bracket of the present invention includes an arc-shaped plate 61 that fits the surface of the thigh, an adjusting block 62 for adjusting the position of the thigh bracket, an L-shaped bracket 64 for connecting the arc-shaped plate 61 to the adjusting block 62, and an adjustable position set screw handle 65, two self-locking positioning spring pins 63, 66 provided on the adjusting block 62.

[0019] See Figure 3As shown, a U-shaped groove 621 that can slide on the thigh support rod 34 and a vertical groove 622 perpendicular to the opening direction of the U-shaped groove 621 are respectively formed on the adjusting block 62. The openings of the U-shaped groove 621 and the vertical groove 622 are narrow slits with an opening width smaller than the inner width of the groove. An installation hole 623 that horizontally penetrates the opening positions of the U-shaped groove 621 and the vertical groove 622 is provided on the adjusting block 62. The screw 651 of the adjustable set handle 65 is rotatably arranged in the installation hole 623. Rotating the handle 652 of the adjustable set handle 65 causes the screw 651 to rotate simultaneously. The screw 651 can tighten the openings of the U-shaped groove 621 and the vertical groove 622. When rotating the handle 652 in the opposite direction, the screw 651 can loosen the U-shaped groove 621 and the vertical groove 622.

[0020] Combined with Figure 2 , the horizontal end of the L-shaped bracket 64 is fixed to the back of the arc-shaped plate 61 by screws. The vertical end of the L-shaped bracket 64 passes through the vertical groove 622 from the bottom upwards. And a row of adjustment holes 67 are provided on the vertical end of the L-shaped bracket 64. An installation hole 624 leading to the inside of the groove is provided on the vertical groove 622 of the adjusting block 62. A self-locking positioning spring pin 63 is installed in the installation hole 624. The self-locking positioning spring pin 63 has a spring and a plug pin inside the cylinder. When there is no external force, the internal plug pin passes through the installation hole 624 and abuts against the adjustment hole 67 of the L-shaped bracket 64 under the action of the spring.

[0021] See Figure 3 , an installation hole 625 leading to the inside of the groove is provided at the bottom of the adjusting block 62 and beside the opening of the U-shaped groove 621. A self-locking positioning spring pin 66 is installed in the installation hole 625 (see Figure 2 ). A row of positioning screw holes 68 are provided at the bottom of the thigh support rod 34. The internal plug pin of the self-locking positioning spring pin 66 is stuck in the positioning screw hole 68.

[0022] The screw 651 of the adjustable set handle 65 penetrates through the U-shaped groove 621 and the vertical groove 622 of the adjusting block 62 from under the thigh support rod 34 and is locked in the installation hole 623. Rotating the handle 652 of the adjustable set handle 65 causes the screw 651 to rotate, loosening the U-shaped groove 621 clamped on the thigh support rod 34, thus releasing the fixation. At the same time, pull out the plug pin of the self-locking positioning spring pin 66 by hand so that the self-locking positioning spring pin 66 is not stuck in the positioning screw hole 68. The adjusting block 62 can then freely slide on the thigh support rod 34 to adjust the position. When moving the adjusting block 62 to the appropriate screw hole position, release the hand and the self-locking positioning spring pin 66 will be pushed into the new screw hole position under the action of the spring. Then rotate the handle in the opposite direction to make the screw 651 tighten the U-shaped groove 621 and re-clamp it on the thigh support rod 34, thus realizing the position adjustment of the thigh bracket to adapt to the leg lengths of different people.

[0023] When adjusting the height, similarly rotate the handle 652 of the adjustable set handle 65. The screw 651 rotates to loosen the vertical groove 622. Pull out the self-locking positioning spring pin 63 by hand to make the internal pin leave the adjustment hole 67. Move the L-shaped bracket 64 up and down to the appropriate position, and then release the hand to make the self-locking positioning spring pin 63 catch on the adjustment holes 67 at different heights. Rotate the handle 652 in the reverse direction to clamp the L-shaped bracket 64 again, realizing the adjustment of the height position of the arc plate 61 to adapt to the leg shapes and thicknesses of different people and achieving better comfort.

[0024] Multiple longitudinal notches 69 are formed on the back surface of the arc plate 61, facilitating the strap (not shown in the figure) to pass through the notches 69 from the back and be fixed on the arc plate 61. The two ends of the strap are provided with Velcro. When in use, the thigh is closely attached to the arc plate 61, and the strap is wound around the thigh and fixed through the Velcro.
