Abstract

The utility model relates to an igniting torch, which belongs to a lighter with gaseous fuel. The actions of an igniting button can be confined by dialing a safety switch mechanically of the safety device of an existing igniting torch, and the safety switch can not be controlled automatically. If the safety switch is forgotten to be dialed to the off-position, the problem of button misoperation can be caused. The utility model is characterized in that the self control safety device is composed of a button, the safety switch and a wane. The move of the button is controlled by the mutual contact of two longitudinal ribs of the tongue of the safety switch and the two ribs of the button. At the same time, the air-out of an air-out needle can be indirectly controlled through the rotation of the wane by the button. The safety switch and the pressing button are linked to move and synchronously operated, which enables the normal ignition to be achieved, and thus the use safety is enhanced.
