[0039] In this embodiment, the base 100 is in the shape of a rectangle, having a top surface, a bottom surface relative to the ground, and four side surfaces. An extension plate 110 is arranged on two opposite side surfaces of the four side surfaces. The extension plate 110 extends in a direction away from the bottom surface. A threaded through hole is arranged at the end away from the extension plate 110. The axial direction of the threaded through hole is arranged in a vertical direction. The threaded rod 121 of the fixing member 120 is connected to the threaded through hole by a thread. When the threaded rod 121 rotates, the threaded rod 121 moves along the axial direction of the threaded through hole, so that the abutment seat 122 at the bottom end of the threaded rod 121 can abut against the ground, thereby increasing the stability of the base 100 and preventing the base 100 from moving relative to the ground, or the abutment seat 122 is away from the ground, so as to facilitate the movement of the base 100.
