[0028] Among them, as shown in Figure 3 and Figure 4As shown, the upper support assembly 3 consists of an upper seat plate 301 and an upper seat plate limiting structure 302. The upper seat plate limiting structure 302 is a circular ring, which is set as a circular ring for easy processing and manufacturing. The lower support assembly 1 consists of a lower seat plate 102 and a side slide 101. The two sides of the boss of the lower seat plate 102 are straight sections and are welded with side slides 101. The four corners of the lower seat plate 102 are all provided with lower anchoring assemblies 10 of the same specifications.

[0029] Among them, a pair of side guide rails 8 are provided, which are symmetrically fixed in the upper seat plate limiting structure 302 by fixing bolts 9. The inner wall surface of each side guide rail 8 is provided with a lateral stainless steel plate 801. After installation, the side slide plate 101 on the lower seat plate 102 and the lateral stainless steel plate 801 on the inner guide rail 8 of the upper seat plate limiting structure 302 form a sliding guide effect.

[0030] like Figures 1 to 5 As shown, in this embodiment, it should be noted that the actual size of each component in the application document is selected for installation before implementation based on actual on-site needs.
