[0053] Multiple adjustment platforms 2 are mounted on the underside of the base 1, and each adjustment platform 2 is connected to the base 1 via a vertical drive member 5, allowing it to move toward or away from the base 1. Specifically, the vertical drive member 5 is fixed to the base 1, and its power output is connected to the adjustment platform 2. When the vertical drive member 5 is activated, the adjustment platform 2 can move relative to the base 1, increasing or decreasing the distance between the adjustment platform 2 and the base 1, thereby adapting to different support surfaces.

[0054] The lower side of each adjustment platform 2 has multiple support arms 6, each support arm 6 is used to fit with the support surface and is located on the inner side of the base body 1; wherein, fitting means that the end face of the support arm 6 swings relative to the adjustment platform 2 to fit with the support surface. In this state, the maximum contact area and the most stable support effect can be obtained.

[0055] In the embodiment of the present application, by cooperating with the adjustment platform 2 and the support platform 3, the outer and inner sides of the base body 1 both have support points, and the multiple support arms 6 located on the inner side can all fit with the support surface, thereby ensuring the overall stability of the base body 1.
