The inner side of the first limiting block 13 is provided with a first arc-shaped guide surface 131 in the vertical direction. A second limiting block 14 is arranged on the right side of the top of the support rod 11. The inner side of the second limiting block 14 is provided with a second guide surface 141 matching the first guide surface 131. A transverse through hole 15 is provided on the second limiting block 14. The through hole 15 is rotatably connected to the connecting shaft 2.
