A through-type transverse groove 10 is provided on the lower surface of the support platform 1. A guide rod 11 is fixedly connected to the left and right sides of the inner side of the transverse groove 10. A sliding block 12 is slidably connected to the outer side wall of the guide rod 11. A support rod 13 is rotatably connected to the lower surface of the sliding block 12 via a rotating shaft. A gear 14 is rotatably connected to the lower surface of the support platform 1 on the left side of the transverse groove 10 via a rotating shaft. The upper left side of the support rod 13 is rotatably connected to the lower center of the gear 14 via a rotating shaft. A gear 2 15 is rotatably connected to the lower surface of the support platform 1 in front of the gear 14 via a rotating shaft. A control motor 16 is provided on the lower surface of the gear 2 15. The top end of the output shaft of the control motor 16 is fixedly connected to the lower center of the lower surface of the gear 2 15. The lower surface of the control motor 16 is fixedly connected to the lower surface of the support platform 1. A fixing plate 17 is fixedly connected to the upper surface of the sliding block 12. The upper surface of the fixing plate 17 is fixedly connected to the lower surface of the moving plate 3. In use, place the pressing ball 7 at the hip joint. The motor 16 drives gear 2 15 to rotate, which meshes with gear 1 14, causing gear 1 14 to rotate. This, in turn, pushes the sliding block 12 along the guide rod 11 within the transverse groove 10 via the support rod 13. The sliding block 12, through the fixing plate 17, drives the moving plate 3 to move stably along the slide rail 2. The slide rail 2 provides precise guidance for the movement of the moving plate 3, ensuring a smooth and unbiased movement. The fixing box 5 is securely mounted on the moving plate 3 via the clearance groove 4. The movable groove 6 allows the pressing ball 7 to adapt to the flexible rotation of the hip joint. The automatic and smooth movement of the moving plate 3 then drives the pressing ball 7 to provide targeted auxiliary stretching of the hip joint, eliminating the need for manual effort. Adjustable and easy to operate, requiring no professional guidance, the drive mechanism of motor 16 enables stable control of stretching force and movement speed, avoiding uneven or overstretching issues caused by manual operation, effectively reducing the risk of sports injuries. The rotating design of the pressing ball 7 provides a better fit to the hip joint, enhancing comfort during stretching. The dual guiding structure of slide rail 2 and guide rod 11 ensures stable and reliable operation. The overall structure is compact and space-saving, suitable for daily rehabilitation training and yoga assistance for people with limited hip joint mobility. It can help gradually improve the range of motion of the hip joint, meet the stretching needs of different groups, and provide a safe, efficient, and convenient auxiliary stretching solution for people with limited hip joint mobility.

[0017] like Figure 1 and Figure 2 As shown, multiple support legs 8 are fixedly connected to the lower surface of the support platform 1, and anti-slip pads 9 are fixedly connected to the lower surface of each of the multiple support legs 8. Multiple support legs 8, fixedly connected to the lower surface of the support platform 1, provide stable support for the entire device. They evenly distribute the weight of the support platform 1 and the components above it, ensuring that the device remains level and stable during use and preventing tilting or swaying due to uneven force. The distribution design of multiple support legs 8 further enhances the load-bearing capacity and structural stability of the device. The anti-slip pads 9 fixed to the lower surface of the support legs 8 increase the friction with the ground, effectively preventing displacement of the device during the process of the control motor 16 driving the moving plate 3 to move and pressing the ball 7 for assisted stretching. This ensures the accuracy and safety of the stretching operation. At the same time, the anti-slip pads 9 also play a role in cushioning and shock absorption, reducing the vibration generated during device operation and reducing noise. This further improves the ease of use and applicability of the device, providing more reliable support for assisted stretching for people with limited hip joint mobility.

[0018] like Figure 1 and Figure 3 As shown, a yoga mat 18 is provided on the upper surface of the movable plate 3, and a cushion 19 is provided on the left side of the yoga mat 18. The yoga mat 18 on the upper surface of the moving plate 3 increases the soft touch and frictional resistance between the body and the moving plate 3, avoiding discomfort caused by direct contact between the body and the hard moving plate 3 during stretching. It also effectively prevents the body from slipping during device operation or voluntary movement, ensuring the stability and safety of movement execution. The yoga mat 18 provides a flat and comfortable working surface, allowing patients to perform stretching movements beneficial to the hip joint on the moving plate 3 according to their own hip joint rehabilitation needs, flexibly adapting to the training needs of different rehabilitation stages. The pillow 19 is precisely designed for use when the patient is on their side. When the patient is on their side performing assisted stretching or voluntary training, the pillow 19 provides soft and stable support for the arm at the support point, preventing poor blood circulation, soreness, and discomfort caused by prolonged pressure or improper force on the arm, effectively reducing limb compression damage. The combination of the two optimizes the ergonomic design of the device, allowing patients to focus on hip joint rehabilitation training without worrying about the protection of the limb support points, and enriches the training methods, taking into account both automated assisted stretching and voluntary stretching needs.

[0019] like Figures 1-5 As shown, an adjustment groove 20 is provided on the upper surface of the support platform 1 and below the clearance groove 4. The left and right sides of the inner side of the adjustment groove 20 are rotatably connected to the adjustment screw 21 through a rotating shaft. An adjustment block 22 is threadedly connected to the outer side wall of the adjustment screw 21. The upper surface of the adjustment block 22 is fixedly connected to the lower surface of the fixed box 5. A rotating circular plate 23 is provided on the right side of the support platform 1. A fixed rod 35 is fixedly connected to the left side of the rotating circular plate 23. The left end of the fixed rod 35 is fixedly connected to the right end of the adjusting screw 21. A handle 24 is fixedly connected to the right side of the rotating circular plate 23. By gripping the handle 24 and rotating the rotating disc 23, the adjusting screw 21 can be rotated synchronously via the fixed rod 35. Utilizing the threaded transmission principle, the adjusting block 22 is driven to slide smoothly along the adjusting groove 20, thereby causing the pressing ball 7 in the fixed box 5 and the movable disc 6 to move left and right. This allows for precise adjustment of the pressing ball 7's position. This adjustment structure is simple and convenient to operate, requiring no additional tools. It can flexibly adjust the corresponding position of the pressing ball 7 according to the height, body type, and specific hip joint position differences of different users, ensuring that the pressing ball 7 accurately fits the target stretching area of ​​each user's hip joint. This effectively improves the targeting and adaptability of the assisted stretching, avoids affecting the stretching effect due to positional deviations, and further broadens the applicable user range of the device. It allows people with limited hip joint mobility to obtain a precise and effective assisted stretching experience. At the same time, the adjusting groove 20 guides and limits the sliding of the adjusting block 22, ensuring a smooth and non-deviation-free adjustment process.

[0020] like Figure 4 and Figure 5As shown, a fixing block 25 is fixedly connected to the right side of the upper surface of the support platform 1 and to the left side of the rotating circular plate 23. A sliding cavity 26 is opened inside the fixing block 25. A movable plate 27 is slidably connected inside the sliding cavity 26. A positioning rod 28 is fixedly connected to the right side of the movable plate 27. Multiple through-hole positioning circular holes 29 are opened on the right side of the rotating circular plate 23. The right end of the positioning rod 28 extends into the upper positioning circular hole 29. A spring 30 is fixedly connected to the left side of the movable plate 27 and the left side of the sliding cavity 26. A through-hole actuating groove 31 is opened on the upper surface of the sliding cavity 26. A guide rod 32 is fixedly connected to the left and right sides of the actuating groove 31. An actuating plate 33 is slidably connected to the outer wall of the guide rod 32. The lower surface of the actuating plate 33 is fixedly connected to the upper surface of the movable plate 27. When the position of the pressing ball 7 needs to be adjusted, the actuating plate 33 is moved to the left, which drives the movable plate 27 to slide smoothly along the sliding cavity 26, compressing the spring 30. This causes the positioning rod 28 to simultaneously exit the corresponding positioning hole 29, releasing the lock on the rotating plate 23. At this time, the position of the pressing ball 7 can be adjusted by rotating the rotating plate 23 with the handle 24. After adjusting to the target position, the actuating plate 33 is released. The spring 30 pushes the movable plate 27 back to its original position under the action of elastic restoring force. The positioning rod 28 is reinserted into the corresponding positioning hole 29 to complete the relocking. The entire positioning structure is easy to operate and requires no additional tools. The guide rod 32 ensures that the movable plate 27 slides smoothly without jamming. The elastic force of the spring 30 makes the positioning lock more reliable. This not only ensures the flexibility of adjusting the position of the pressing ball 7, but also improves the stability and safety of the device during use, further adapting to the precise adjustment needs of different people for the position of the pressing ball 7.

[0021] like Figure 4 As shown, the outer wall of the grip 24 is fitted with an anti-slip sleeve 34; The anti-slip sleeve 34, which is fitted on the outer wall of the grip 24, is made of a soft, non-slip material. Its surface texture can effectively increase the frictional resistance between the hand and the grip 24, preventing slippage caused by sweaty hands, uneven force, or prolonged gripping when the user holds and rotates the grip 24 to adjust the position of the pressing ball 7. This ensures grip stability and force precision during operation. At the same time, the softness of the anti-slip sleeve 34 conforms to the contour of the hand, reducing the pressure of the grip 24 on the palm, relieving soreness and discomfort caused by prolonged gripping, and protecting the skin of the hand from friction damage from the hard grip 24. This makes it more comfortable and effortless for the user to adjust the position of the pressing ball 7, further improving the convenience of device operation and user experience.
