The bottom side of the sliding assembly is slidably connected to a strip slider 26, and a trapezoidal opening 27 is provided at the left end of the strip slider 26 for limiting the button 24 so that the button 24 can push the strip slider 26 to slide when sliding. A spring 28 is fixedly connected to the right side of the strip slider 26, and the spring 28 is squeezed when the strip slider 26 slides.

[0031] Working principle: When facing different user groups, the rotating rod 3 is driven to rotate by holding the turning handle 4 and applying a rotating force, and at the same time, the circular plate 6 is driven to rotate and limit inside the right-angle plate 1, and through the limit of the right-angle plate 1, the threaded rod 5 can drive the sliding block 7 to slide, thereby resisting the rotating column 8, so that it can rotate, and at the same time rotate at the bottom of the sliding plate 9, so as to slide through the sliding plate 9, and at the same time, the telescopic rod 11 at the bottom is used to prevent the sliding plate 9 from sliding, and the sliding plate 9 pushes the top arc plate 16 to slide to use the height difference between the legs and heels of different users, and the heel is placed on the top of the arc plate 16, through the flexible material of the arc plate 16, and the arc plate 16 will press the sliding rod 15 to slide on the inner wall of the fixed tube 12, and then push the triangular column 14 to slide on the inner wall of the fixed tube 12 and squeeze the spring 13, so that the spring 13 can store elastic potential energy, thereby giving the heel a force in the opposite direction, thereby improving the comfort of the user;

[0032] After the heel is placed, the user's comfort is further improved by the flexible material of the right-angle plate 1 and the two L-shaped plates 2. The fixing strip 19 is held through the square block 21, and the button 24 is pressed to drive the limiting plate 25 to slide inside the square block 21. The limiting plate 25 is provided with a groove inside to adapt to the activity space of the limiting plate 25. The button 24 pushes the strip slider 26 to open the inclined surface of the trapezoidal opening 27, thereby pushing the strip slider 26 to slide and squeeze the spring 28, so that the fixing strip 19 can stably pass through the square block 21. After sliding to a suitable position, the force on the button 24 is sent, so that the spring 28 can use the reset force to push the strip slider 26 to slide inside the square opening 20 opened by the fixing strip 19 for engagement.
