The outer surface of the pin shaft 20 is sleeved with a tape measure 7. On one side of the movable cavity 19, a through groove 21 is provided.

[0025] Furthermore, a plurality of airbags 12 are installed on the inner surfaces of the fixed ring A4 and the fixed ring B9. Below the rear end surface of the other vertical plate 3, an air pump 11 is installed. On the upper end surface of the air pump 11, a three-way valve is installed. The three-way valve is connected to the two groups of airbags 12 through an air pipe A and an air pipe B respectively. A storage battery is installed inside the vertical plate 3, and the storage battery is electrically connected to the air pump 11. By controlling the switch of the air pump 11, the airbags 12 can be inflated, so that the fixed ring A4 and the fixed ring B9 are worn stably, and the storage battery can provide power for the air pump 11.

[0026] The front and rear end surfaces of the pin shaft 20 and the inner wall of the movable cavity 19 are rotatably connected through bearings. A torsion spring is sleeved on the outer surface of the pin shaft 20. The other end of the tape measure 7 is fixedly connected to the upper end surface of the movable seat 8.
