[0033] In this embodiment, the first connecting plate 1 and the second connecting plate 2 are connected and fixed in a cross shape by the cooperation of the mounting groove 4 and the slot 5. This makes the base support structure more reasonably compact and stronger, and easier to construct. At the same time, the structure is simple, easy to process, and has low processing cost. In addition, it is lightweight. The specific process is as follows: First, the slot 5 at the center of the second connecting plate 2 is inserted into the mounting groove 4 of the first connecting plate 1 from top to bottom, so that the center of the second connecting plate 2 is completely located in the mounting groove 4, ensuring that there is no height difference between the top centers of the first connecting plate 1 and the second connecting plate 2. Then, the two are fixed firmly by welding or other methods. Next, the cross structure formed by the two is attached to the surface of the welding ball 3. Finally, the connection is fixed by full welding.

The sliding plate 8 and the sliding groove 10 correspond one-to-one. The top shape of the sliding plate 8 matches the top shape of the first connecting plate 1 or the second connecting plate 2. The bottom of the sliding plate 8 is slidably installed in the sliding groove 10, and the sliding direction is vertical. Multiple springs 9 are installed at intervals in the sliding groove 10 and are fixedly connected to the bottom of the sliding groove 10. The bottom of the sliding plate 8 abuts against the multiple springs 9.
