The third fixing element 31 includes a third bolt and a third nut. The middle part of one end of the third bolt is smooth, and both ends have threaded grooves. When the threaded groove part is threadedly connected to the mutually approaching ends of the first telescopic rod 24 and the connecting plate 26, the first telescopic rod 24 and the connecting plate 26 are in a non-rotatable state. When the smooth part is sleeved between the first telescopic rod 24 and the connecting plate 26, the first telescopic rod 24 and the connecting plate 26 are in a rotatable state. The side of the connecting rod 22 is rotatably connected to a second telescopic rod 17. The bottom end of the second telescopic rod 17 is rotatably connected to the sliding block 8. The end of the second telescopic rod 17 away from the connecting rod 22 is fixedly connected to a footrest 11. The footrest 11 can be adjusted through the second telescopic rod 17 so that the footrest 11 can completely fit the soles of the patient's feet, avoiding the bending of the patient's calf and providing a support point for the soles of the patient's feet. Support brackets 19 and straps 20 are fixedly installed at the top of both the second telescopic rod 17 and the connecting rod 22. The support brackets 19 can support and lift the patient's buttocks and legs. The straps 20 are fixedly installed on the top of the support brackets 19.

[0030] Embodiment Two: Please refer to Figure 1 -Figure 6 Based on Example 1, the bottom end of the air cylinder 4 is fixedly installed at the bottom of the vertical frame 1 through the first support block 29. The top of the first support block 29 is fixedly connected to the bottom of the air cylinder 4. At both ends of the bottom of the first support block 29, two support columns are provided, and the bottom of the support columns is fixedly connected with support pads, and the support pads are fixedly connected to the bottom of the vertical frame 1, thereby realizing the installation of the air cylinder 4. By setting two support columns and support pads, a through hole can be formed between the first support block 29 and the vertical frame 1, facilitating the connection of the rope 3. A support column 2 is fixedly connected inside the vertical frame 1. The support column 2 and the output end of the air cylinder 4 are slidably connected through a sliding vertical plate 27. The support column 2 can not only play a role in connecting and fixing the vertical frame 1, but also play a role in guiding and limiting the movement of the sliding vertical plate 27;

[0031] Please refer to Figure 2 and Figure 4 The top of the sliding vertical plate 27 is fixedly connected to the pull ring 28. Fixing the sliding vertical plate 27 and the pull ring 28 can fix one end of the rope 3, and the movement of the sliding block 8 can be driven by pulling the rope 3;

[0032] Please refer to Figure 1 、 Figure 2 and Figure 6 At both ends of the vertical frame 1 and at one end of the slide rail 7 away from the vertical frame 1, a first pulley 5, a second pulley 6 and a third pulley 9 are respectively fixedly installed. The first pulley 5, the second pulley 6 and the third pulley 9 are respectively sleeved with the rope 3. The first pulley 5 and the second pulley 6 are respectively fixedly installed at the upper and lower ends of the vertical frame 1, and the first pulley 5 and the second pulley 6 are installed on the same side of the vertical frame 1. The third pulley 9 is installed at the top of one end of the slide rail 7 away from the vertical frame 1, and a second support rod 16 is fixedly connected between the third pulley 9 and the seat 10. The seat 10 can be further supported through the second support rod 16. One end of the rope 3 away from the air cylinder 4 is fixedly connected to the sliding block 8. The sliding block 8 and the concave rod 21 are fixedly connected through a second fixing element 30. The second fixing element 30 includes a second threaded bolt and a second nut. The middle part of one end of the second threaded bolt is smooth, and both ends have threaded grooves. When the part with the threaded groove is threadedly connected to the mutually approaching ends of the concave rod 21 and the sliding block 8, the concave rod 21 and the sliding block 8 are in a non-rotatable state. When the smooth part is sleeved between the concave rod 21 and the sliding block 8, the concave rod 21 and the sliding block 8 are in a rotatable state, thereby realizing the adjustment of the angle of the concave rod 21. An elastic cord 12 is fixedly connected between the sliding block 8 and the vertical frame 1. Both ends of the elastic cord 12 are respectively fixedly installed between the vertical frame 1 and the sliding block 8, so that the sliding block 8 can return to its original state when moving, realizing the reciprocating movement of the sliding block 8, and further realizing continuous joint rehabilitation movement.

[0033] The working principle of the present utility model is as follows: Since this device is a device for rehabilitation exercises of leg joints, when it is necessary to use this device for rehabilitation exercises of leg joints, first, the patient can sit on the seat 10 and place the leg joints on the support tray 19. Then, the legs are bound by the straps 20. This not only prevents the legs from moving during the exercise but also plays a safety protection role for the patient, preventing the patient from falling during the rehabilitation exercise and maintaining the safety of the patient during the rehabilitation exercise. At the same time, the length of the second telescopic rod 17 can be adjusted to facilitate the contact between the patient's soles and the footrest 11, thereby realizing the synchronous movement of the leg joints, and at the same time enabling the legs to have a support point to facilitate the soles to support and avoid the bending of the leg joints;

[0034] During the movement process, according to the patient's leg rehabilitation exercise requirements, the patient can choose to bend the calf joints or hip joints. When it is necessary to perform bending rehabilitation exercises on the calf joints, the connection state between the second telescopic rod 17 and the connecting rod 22 can be adjusted through the first fixing element 23, so that the second telescopic rod 17 can deflect. At the same time, the second fixing element 30 is adjusted to further adjust the bending angle of the concave rod 21. At this time, through the driving cylinder 4, the movement of the piston rod of the cylinder 4 can drive the sliding vertical plate 27 to slide up and down around the support column 2. During the sliding process of the sliding vertical plate 27, the rope 3 can be driven to perform tensioning and contraction movements around the first pulley 5, the second pulley 6, and the third pulley 9. Through the tensioning and contraction of the rope 3, the sliding block 8 is driven to slide around the slide rail 7. When the sliding block 8 slides, the elastic rope 12 can be driven to perform telescopic movements, so that the sliding block 8 can move back and forth around the slide rail 7. At this time, the concave rod 21 will deflect in an arc with the back-and-forth movement of the sliding block 8, thereby driving the joints of the patient's calf part to bend back and forth, thus realizing the rehabilitation exercise requirements of the calf part; When it is necessary to perform bending exercises on the entire patient's leg, at this time, the hip joints of the leg need to perform bending exercises. Therefore, the third fixing element 31 needs to be adjusted so that the end of the connecting rod 22 close to the seat 10 can bend, driving the entire leg of the patient to bend, thereby realizing the rehabilitation exercise of the entire leg joints of the patient and enabling the joints at different positions of the leg to achieve the effect of rehabilitation exercise.

[0035] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
