[0027] The linkage plate of the present invention can slide on the surface of the slide plate through the movable frame, and the linkage plate squeezes the civil air defense door through the push plate when moving. When the linkage plate moves toward the direction of the fixed seat, the push plate will push the civil air defense door to rotate toward the outer end of the door frame as the linkage plate moves, so that the civil air defense door can be easily opened. When the linkage plate moves, it pushes the inclined plate to move through the bent plate, and when the inclined plate moves, it pushes the civil air defense door to move toward the outer end of the door frame through the rotating shaft frame, thereby further improving the convenience of opening the civil air defense door.
