Unlocking mechanism driven by electrically-triggered gas

The invention discloses an electrically-triggered gas-pushed unlocking mechanism, which belongs to the technical field of robot unlocking and comprises a shell, a shell cover, an inner fixing body, a gas generator, a piston, a locker and a rocker arm. The shell cover is used for sealing the upper opening of the shell; the piston is arranged in the shell and divides the space in the shell into an upper part and a lower part; the gas generator is arranged above the piston and used for releasing gas to push the piston to move downwards. A plurality of locking devices are distributed in the shell in an axial symmetry mode, and the upper portions of the locking devices are fixedly connected with the bottom of the piston. The inner fixing body is arranged between the locking devices, and rocker arms are rotationally arranged at the positions, corresponding to the locking devices, of the circumference of the inner fixing body. The rocker arm comprises a first clamping protrusion and a second clamping protrusion loca
