[0023] Embodiment 2 Referring to Figure 2 and Figure 3 , in this embodiment, a dynamic adjustment assembly 4 is also included, which includes a plurality of horizontal reference plates 41, a computing controller, a plurality of sleeves 42 and a plurality of electric pulling components 43, the horizontal reference plates 41 are suspended on the upper surface of the bottom pivot base 1, the lower surface of the horizontal reference plates 41 is parallel to the horizontal plane, a pressure sensor 44 is arranged between the horizontal reference plates 41 and the upper surface of the bottom pivot base 1, and the pressure sensor 44 is electrically connected to the computing controller.
