The utility model relates to a safety power saving igniting gun. The present igniting gun still can open the air outlet valve under the condition that the piezoelectricity is prevented from discharging; the safety hazard of the leakage of the flammable gas exists, and the operation is uneasy. The utility model is characterized in that a booster element is arranged between the piezoelectric push rod and a snap handle; one end of the booster element is pivoted on the casing; the other end and the central part are respectively matched with the snap handle and the piezoelectric push rod; an air controlled element is sheathed on the air outlet valve; the head part of the air controlled element forms a hook part which can be matched with the pivoted end of the booster element; a safety spring is arranged between one side of the air controlled element and the casing, and can make the hook part disengaged from the range of movement of the pivoted end of the booster element; a control switch abutted with the back side of the hook part is arranged between the other side of the air controlled element and the casing; the control switch is pivoted on the casing, with a part of the control switch exposed outside. The utility model not only can effectively control the operating state of the snap handle, but also can effectively control the operating state of the air outlet valve, realizing the double insurance of the igniting gun with laborsaving operation.
