Four support bars are provided as described above, but not limited thereto, and at least two or more may be provided as long as they can stably support and avoid interference with each other. The first and second support plates 3 and 5 may be formed in a uniform structure to achieve a universal structure, and the first rotating base 1 may be formed in a slider structure similar to the third slider 6 to achieve a symmetrical structure. For example, the first support plate body 32 is also provided with a first elongated hole portion 35 for use in a scene when the leg assembly 9 is attached. Each member body, for example, the first support plate body 32 and the second support plate body 52 is preferably provided with, for example, a long hole or a groove, and the rigidity is ensured while the material is saved and the weight is reduced as much as possible. The support plates and the foot supports are not limited to flat plates, but can also be curved plates which are contoured to the legs, and the specific shapes can be changed and replaced according to actual needs so as to adapt to patients with different body sizes. The locking screws are fixed by shaking handles or butterfly nuts and the like, so that the operation is more convenient, the two adjustable triangular supporting mechanisms can easily enter a movable state without influencing the stability of fixing in the operation, and the observation and the control of a force line are facilitated. The rotation pairs are illustrated as being hinged, but not limited thereto, and other rotatable means such as ball sockets may be used.
