When the angle of the patient's affected limb changes, the supporting seat 107 will be squeezed, so that the supporting seat 107 squeezes the adjusting airbag 106 below it, causing the adjusting airbag 106 to shrink. The shrinking adjusting airbag 106 transmits air to other adjusting airbags 106 through the connecting tube 108, causing the other adjusting airbags 106 to expand and drive the corresponding supporting seat 107 to rise, thereby causing the supporting seat 107 that is not in contact with the affected limb to rise and support the affected limb. It can be understood that the aforementioned scheme can be used to automatically adapt to changes in the angle of the patient's affected limb and improve the patient's comfort when adjusting the height of the patient's affected limb. It can also be used to clamp and fix the patient's affected limb.

[0026] According to this specific embodiment, the lifting plate 102 is slidably installed inside the housing 101 , and the lifting assembly 103 is disposed inside the housing 101 and drives the lifting plate 102 to be lifted or lowered.
