When the sliding pin 5 moves upwards and touches the spiral groove 13, the limit stop ring 8 abuts against the bottom end of the rod part 23, and the limit pin 7 penetrates through the limit hole 14 and is arranged in the limit opening 81 to prevent the lock cylinder 1 from moving upwards.

In a locked state, when the bottom of the cylinder is inflated to reach a certain pressure, the piston 4 moves upwards, and the sliding pin shaft 5 moves upwards along with the piston 4 and touches the spiral groove 13. The spiral groove 13 is a groove with a large friction coefficient, when the sliding pin 5 moves upwards and touches the spiral groove 13, the sliding pin 5 will move along the spiral groove 13 because the lock core 1 of the limiting structure cannot move upwards, and at the moment, the spiral groove 13 receives a force which is the same as the groove direction and is inclined upwards, and the force has a component force in a radial direction to force the rotating rod 12 to rotate.
