A front side of the bottom of the base 1 is fixedly connected with an L-shaped connecting block 2. A rotating shaft 3 is rotatably connected inside the L-shaped connecting block 2. This bearing carries the rotating function of the entire leg fixing system and allows various angle adjustments and fixations of the knee. Two leg fixing plates 4 are rotatably connected to the outside of the rotating shaft 3 and can be adjusted according to needs to ensure the stability of the leg during training. A sliding plate 5 is slidably connected inside the leg fixing plate 4. A resilient support plate 6 is fixedly connected to a proximate side of the two sliding plates 5. A fixing component for fixing the position of the leg is provided on the top of the resilient support plate 6. The fixing component includes a binding female sticker 7 and a binding male sticker 8. The bottoms of the binding female sticker 7 and the binding male sticker 8 are respectively fixedly connected to the outside of the sliding plate 5. The tops of the binding female sticker 7 and the binding male sticker 8 are in contact with each other to help adjust and fix the position of the leg and ensure safety and comfort during training. A positioning rod 9 is rotatably connected inside the two leg fixing plates 4, which is docked with the popliteal fossa to help fix and adjust the position of the knee. Two connecting bands 10 are fixedly connected to the outside of the positioning rod 9. A proximate side of the two connecting bands 10 is fixedly connected with a heavy pressure bag sleeve 11. A plurality of storage grooves are formed inside the heavy pressure bag sleeve 11 for placing a plurality of salt bags. A plurality of blocking buckle straps 12 are fixedly connected to an outside side of the heavy pressure bag sleeve 11 to ensure the safety and stability of the salt bags during use.
[0034] Refer to Figure 1 , Figure 5 , a connecting block one 13 is fixedly connected to the bottom of the base 1. A cylinder base 14 is rotatably connected to the outside of the connecting block one 13. A driving cylinder 15 is fixedly connected to a front side of the outside of the cylinder base 14. A connecting wire 18 is fixedly connected to a front side of the outside of the cylinder base 14. A control handle 20 is fixedly connected to the top of the connecting wire 18;
[0035] A plurality of mounting blocks 21 are fixedly connected to the bottom of the base 1. A fixing bolt 23 is threadedly connected inside the mounting block 21. A sliding block 22 is threadedly connected to the outside of the fixing bolt 23. A bracket 24 is fixedly connected to the bottom of the plurality of sliding blocks 22. A rubber soft pad 25 is fixedly connected to the top of the base 1. Rotating shafts 26 are rotatably connected to the left and right sides inside the rubber soft pad 25. An armrest 27 is fixedly connected to the outside of the rotating shaft 26.
[0036] Refer to Figure 1 , Figure 6 , a concave connecting block 16 is fixedly connected to the bottom of the two leg fixing plates 4. A connecting block two 17 is fixedly connected to the bottom of the concave connecting block 16. The output end of the driving cylinder 15 is fixedly connected to the outside of the connecting block two 17. A protective wire tube 19 is fixedly connected to the outside right side of the base 1. The outside of the connecting wire 18 is slidably connected inside the protective wire tube 19.
[0037] Working principle: The patient first sits at the front end of the rubber soft pad 25. The elastic support plate 6 on the leg fixing plate 4 will fix the patient's thigh at different positions according to needs to ensure the stability of the leg during the training process. After fixing, the patient places the back of the knee on the positioning rod 9. Subsequently, an appropriate amount of salt bag is placed inside the heavy pressure bag sleeve 11, and the heavy pressure bag sleeve 11 is then placed on the patient's knee. In this way, the patient can carry out independent training under different circumstances to enhance the flexibility of the knee.
[0038] When fixing the calf, the patient sits at the rear side of the rubber soft pad 25, places the thigh on the front side of the soft pad, and once again uses the elastic support plate 6 sliding on the leg fixing plate 4 to fix the calf. After the fixation is completed, the driving cylinder 15 starts to work, pushing the connecting block two 17 to move the leg fixing plate 4 on the concave connecting block 16. Since the leg fixing plate 4 is connected by the rotating shaft 3, the linear motion of the driving cylinder 15 is effectively converted into the rotation of the leg fixing plate 4, thereby simulating the bending and straightening actions of the human lower limb.
[0039] Throughout the process, the patient can carry out knee training at different angles and intensities. The design of the heavy pressure bag provides an additional load, enhancing the training effect. In this way, the device can effectively assist the patient in rehabilitation training and promote the recovery of knee function.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
