[0024] There are four stabilizing rods 23 , which are symmetrically distributed on the base plate 1 in groups of two. The four unfolded stabilizing rods 23 are used to improve the stability of the base plate 1 during support.

[0025] In addition, a support groove is provided on the outside of the support rod 27 at one end of the stabilizing rod 23 close to the support block 22, and the end of the support rod 27 located on the inside of the stabilizing rod 23 is T-shaped.
