[0023] like Figures 1 to 7 As shown, in order to embed the embedded tube 63 when it is not needed, the lower support plate 1 is further inverted U-shaped, and an embedded groove 11 is provided below the lower support plate 1; the embedded tube 63 at the outer end of the rotating embedded rod 62 is embedded in the embedded groove 11.

[0024] like Figures 1 to 7 As shown, in order to adjust the column 61, a plurality of rotating embedded rods 62 can be driven to rotate. Furthermore, a floating cavity 12 is provided on the upper part of the lower support plate 1, and a plurality of driving grooves 13 are evenly arranged around the lower part of the lower support plate 1, and the plurality of driving grooves 13 are connected to the floating cavity 12. The stable adjustment mechanism 6 also includes a lifting horizontal plate 64, a lifting vertical plate 65, a rotating block 66, and an extension column 67. The lifting horizontal plate 64 is slidably installed in the floating cavity 12, and the lifting horizontal plate 64 is threadedly screwed with the adjusting column 61 through a threaded hole in the middle. The four sides of the lifting horizontal plate 64 A plurality of lifting longitudinal plates 65 are evenly installed on the lower side of the circumference, and the lower end of the lifting longitudinal plate 65 slides up and down and extends into the driving groove 13. A rotating block 66 is rotatably installed in each driving groove 13.
