[0039] Further, the push-pull component 302 includes an inclined groove 302a arranged on the side wall of the lifting plate 301b, a connecting rod 302b is slidably connected in the inclined groove 302a, and a first sliding groove 302c is opened on the inner wall of the fixed seat 106; wherein, the connecting rod 302b is slidably connected to the first sliding groove 302c; the connecting component 303 includes a moving block 303a arranged on the lower side of the connecting rod 302b, a rotating column 303b is fixedly connected to the side wall of the moving block 303a, and a connecting block 303c is rotatably connected to the outer surface of the rotating column 303b; the guide component 304 includes a guide block 304a arranged on the connecting block 303c, a first guide groove 304b is opened on the inner wall of the third connecting tube 104, a second guide groove 304c is opened on the inner wall of the reversing groove 202b, and a third guide groove 304d is opened on the inner walls of the first connecting tube 102 and the second connecting tube 103.

[0040] Specifically, a moving block (303a) is fixedly connected to the lower side of the connecting rod 302b. The connecting rod 302b is arranged in a T shape. Two moving blocks 303a are arranged symmetrically. A plurality of connecting blocks 303c are arranged, and the plurality of connecting blocks 303c are movably connected together through a rotating column 303b.
