Aircraft firer ejection insurance and insurance release assembly

The invention provides an aircraft firer ejection insurance and protection releasing assembly. The aircraft firer ejection insurance and protection releasing assembly comprises an insulating shell, a trigger sleeve and a firer actuating cylinder. An ignition actuating cylinder is slidably installed in the insulating shell in the axial direction, trigger sleeves are slidably installed on the two sides in the insulating shell in the radial direction, and the trigger sleeves on the two sides abut against the peripheral side of the ignition actuating cylinder under the action of elastic force. The pyrotechnic actuating cylinder comprises a metal conductor and an insulating special-shaped body, and the metal conductor is mounted on the insulating special-shaped body; and through axial movement of the pyrotechnic actuating cylinder, when the trigger sleeve abuts against the insulating special-shaped body, the trigger sleeve is in a non-conducting state, and when the trigger sleeve abuts against the metal conductor,
