[0029] Furthermore, the first connecting rod 18 is rotatably arranged on the lower surface of one end of the first folding rod 14 close to the second auxiliary rod 17, and one end of the second connecting rod 19 is rotatably arranged on the upper surface of one end of the second folding rod 15 close to the first auxiliary rod 16.
