The pin hole provided in the above manner can be used to couple the connecting rope 6 with a relatively gradual upward movement trend along with the downward movement of the piston, so that the bolt 61 is deformed due to the gradual increase of the torque applied to the bolt, and the connecting rope is finally separated from the opening. Particularly, when the pin holes are arranged as radial variable through holes, the release of the pins 61 is facilitated, the release resistance of the pins is reduced, and the reliability and stability of the release of the pins are ensured.

According to the utility model, the parachute is ensured to be successfully separated from the parachute cabin and opened by utilizing the elastic potential energy of the crossed elastic ropes, the air pressure control switch and the timing steering engine for triple protection. When the parachute is opened, the parachute pressed on the crossed elastic ropes can be ejected out of the parachute cabin by the elastic ropes. On the other hand, the air pressure control switch and the timing steering engine can doubly ensure the successful release of the elastic rope for closing the cabin door of the parachute cabin when the parachute is opened, thereby ensuring that the parachute is successfully separated from the parachute cabin, and effectively achieving the effect of triple redundancy parachute opening.
