The invention discloses a power-losing trigger device. The power-losing trigger device comprises a frame, an electromagnet and an impacting rod; the impacting rod vertically and movably penetrates through the frame, the upper end and the lower end of the impacting rod are located outside the frame, a limiting buffer cushion is installed on the upper section of the impacting rod, and the lower end is the impacting end. The electromagnet is installed on the frame; an energy storage piece is arranged and has a downward action force on the impacting rod; when the electromagnet is electrified, the impacting rod is positioned through electromagnetic force; when the electromagnet loses power, the keeping force of the electromagnet on the impacting rod is lost, and the impacting rod performs the downward impacting motion under the action force. The power-losing trigger device is implemented through the electromagnet and a middle mechanism, and the electromagnetic force for maintaining the electromagnet is reduced through the middle amplifying mechanism, so that the current, the energy consumption and the cost of the electromagnet are reduced, the service life of the long-time electrification electromagnet is prolonged, automatic resetting of the electromagnet can be achieved, the electromagnet, an energy storage impacting structure and a resetting structure of the power-losing trigger device are simple, and the power-losing trigger device is convenient to use.
