[0019] As a preferred embodiment of the present invention, the steering stabilizer is further provided with a plurality of sliding fixing components. The sliding fixing components include a rotating connecting block, which is fixedly connected to the vicinity of the sliding connection between the steering stabilizer and the connecting rod. The rotating connecting block is also provided with a rotating fastening rod, which is rotatably connected to the rotating connecting block. The other end of the rotating fastening rod away from the rotating connecting block is provided with two sets of curved fastening plates. The curved fastening plates are interlocked with each other and are fastened to the connecting rod.

[0020] The beneficial effects of this invention are as follows: This invention is an angle fixation trainer for ankle joint auxiliary rehabilitation treatment that can freely adjust the exercise angle and perform prone position treatment. The specific operation steps are as follows: After the operator places the leg on the leg placement block, the ankle is placed on the ankle fixing block, and the foot is placed on the foot support plate. Then, the leg and foot are fixed to the device by the third connecting strap and the first bandage. The foot side fixing plate and foot limiting plate provided on the foot support plate can limit the range of motion of the ankle. Then, the buckle block is slid into the sliding guide rods on the back of the foot support plate. After the buckle block is placed between the sliding guide rods, the rotating wheel is buckled into the sliding guide groove. After sliding the foot support plate to the appropriate position, the buckle rotating plate is rotated along the central rotating rod to buckle the rotating wheel buckle groove on the buckle rotating plate into the rotating wheel, thus completing the fixation. At the same time, during the adjustment of supine or prone position, the sliding direction of the sliding guide rod can be adjusted to change the exercise direction.

[0021] After fixing, the movable spherical T-bar slides in the adjustment groove. Before installation, it can slide to the inclined surface of the rotating connecting frame. When preparing for activity, it slides to the plane of the rotating connecting frame. The fixing nut on the rotating thread fixes the spherical T-bar onto the rotating connecting frame, thus completing the fixing. After sliding the push lever out of the connecting cup along the through groove, the inclined fixing block is separated from the inner cavity of the connecting cup. Then, the conical fixing block on the spherical T-bar is placed between the inclined fixing blocks. After releasing the push lever, the inclined fixing block is pulled into the inner cavity of the connecting cup by the elastic force of the second spring. You can then start the exercise.

[0022] During exercise, adjusting the ankle angle causes the connecting cup to rotate the outer concave connecting plate and the inner connecting plate, simultaneously causing the inner and outer elastic telescopic rods to extend and retract. During the extension and retraction of the inner and outer elastic telescopic rods, the movable plates at the ends of the inner and outer elastic telescopic rods cause the rotating rollers on the roller connecting rods to roll along the curved spring plate. Because the connecting cup is at the center of the movement and the inner and outer elastic telescopic rods are placed crosswise, the movement rate and return rate are effectively slowed down, effectively exercising the ankle joint.

[0023] During exercise, in order to cooperate with the implementation of medical methods, the ankle needs to be rotated. After the foot support plate is rotated, the ball T-bar drives the connecting cup to rotate. The connecting cup continues to drive the bending spring plate to rotate, which in turn drives the connecting rod to rotate. Furthermore, the steering stabilizer rotates coaxially around the connecting circle, forcing the ring in the middle of the steering stabilizer to squeeze the round rod fixing block. The round rod fixing block is then subjected to the elastic force of the third spring, which keeps it locked in the round rod groove, thus completing the continued fixation after rotation.

[0024] During medical procedures, the exercise height may need to be changed. The above solution is not applicable in such cases. In this case, the steering stabilizer can slide on the connecting rod by peeling off the curved buckle plate on the rotating buckle rod to adjust the exercise height.

[0025] In practice, the exerciser may be in a bed or other position, which is not conducive to holding the equipment for a long time. After the polygonal fixing holes of the stabilizing support rod are fastened to both sides of the polygonal connecting rod, the other end of the stabilizing support rod is inserted into the top of the perforated support rod. The stabilizing support rod has round hole slots of different heights. Then, the height fixing rod is inserted into the round hole slot of the stabilizing support rod through the through hole of the perforated support rod. An I-beam is placed at the bottom of the perforated support rod to support the overall structure. The fixing through hole on the I-beam is used to assist in fixing it in the working position.

[0026] This device, through its simple structural design, enables ankle joint exercises and adapts to different exercise methods. It can also change the working direction and height during exercise, greatly increasing the product's applicability and facilitating its promotion and use. Attached Figure Description

After the buckle rotating rod 24 provided on the buckle block 23 is placed between the sliding guide rod 21, the rotating wheel 25 is buckled into the sliding guide groove 22. After sliding the foot support plate 15 to a suitable position, the buckle rotating plate 26 is rotated along the central rotating rod 27 to buckle the rotating wheel buckle groove 28 on the buckle rotating plate 26 into the rotating wheel 25, thus completing the fixation. At the same time, during the adjustment of supine or prone position, the sliding direction of the sliding guide rod 21 can be adjusted to change the exercise direction.

[0061] After fixing, the movable spherical T-bar 31 slides in the adjustment groove 210. Before installation, it can slide to the inclined surface of the rotating connecting frame 29. When preparing for activity, it slides to the plane of the rotating connecting frame 29. The fixing nut 32 on the rotating thread 33 fixes the spherical T-bar 31 to the rotating connecting frame 29, thus completing the fixing. After the push lever 37 slides out of the connecting cup 36 along the through groove, the inclined fixing block 35 is separated from the inner cavity of the connecting cup 36. After the conical fixing block 34 on the spherical T-bar 31 is placed between the inclined fixing blocks 35, the push lever 37 is released. The inclined fixing block 35 is subjected to the elastic force of the second spring 352 to bring the conical fixing block 34 into the inner cavity of the connecting cup 36, and the exercise can begin.

[0062] During exercise, adjusting the ankle angle causes the connecting cup 36 to rotate the outer concave connecting plate 42 and the inner connecting plate 41, simultaneously causing the inner elastic telescopic rod 43 and the outer elastic telescopic rod 44 to extend and retract. During the extension and retraction of the inner elastic telescopic rod 43 and the outer elastic telescopic rod 44, the movable plate 45 at the end of the inner elastic telescopic rod 43 and the outer elastic telescopic rod 44 causes the rotating roller 452 on the roller connecting rod 451 to roll along the curved spring plate 46. Since the connecting cup 36 is at the center of the movement and the inner elastic telescopic rod 43 and the outer elastic telescopic rod 44 are placed crosswise, the movement rate and return rate are effectively slowed down, effectively exercising the ankle joint.

[0063] During exercise, in order to cooperate with the implementation of medical methods, the ankle needs to be rotated. After the foot support plate 15 is rotated, the spherical T-shaped rod 31 drives the connecting cup 36 to rotate. The connecting cup 36 continues to drive the bending spring plate 46 to rotate, and then drives the connecting rod 49 to rotate. Furthermore, the steering stabilizer 51 rotates coaxially around the connecting circle, forcing the ring in the middle of the steering stabilizer 51 to squeeze the round rod fixing block 52. The round rod fixing block 52 is subjected to the elastic force of the third spring 57, which keeps it locked in the round rod groove 511, thus completing the continued fixation after rotation.

[0064] During medical procedures, the exercise height may need to be changed. The above solution is not applicable to such situations. In this case, by peeling off the curved buckle plate 582 on the rotating buckle rod 581 and disengaging it from the connecting rod 49, the steering stabilizer 51 can slide on the connecting rod 49 to adjust the exercise height.

[0065] In practice, the exerciser may be on a bed or in another position where it is not convenient to hold the equipment for a long time. After the polygonal fixing hole 551 of the stabilizing support rod 55 is fastened to both sides of the polygonal connecting rod 54, the other end of the stabilizing support rod 55 is inserted into the top of the perforated support rod 61. The stabilizing support rod 55 is provided with round hole slots 552 of different heights. Then, the height fixing rod 63 is inserted into the round hole slot 552 of the stabilizing support rod 55 through the through hole of the perforated support rod 61. An I-beam plate 62 is placed at the bottom of the perforated support rod 61 to support the overall structure. The fixing through hole 621 on the I-beam plate 62 is used to assist in fixing it in the working position.
