ABSTRACT:
A handy gas torch includes a fuel container, a fuel gas control device, a piezoelectric device, a securing plate, a supporting frame, a burning, and a top cover. During operation, a knob of the fuel gas control device is turned so that fuel in the fuel container is drawn up by a suction tube of a gas supply device. The fuel gas passes through a tube neck of the fuel gas control device, a guide hole, a gas output tube to a fuel gas nozzle of the burning device and then fills a channel. By turning an adjusting knob to bring a knob hole into alignment with an air intake hole, air is induced into the channel to mix with the fuel gas. The fuel mixture is ejected by a fire nozzle of a fire ejecting device. Upon the user's pressing a press handle of the piezoelectric device to cause a boss on a press plate to press against a piezoelectric means, sparks are generated by a lead wire on one side of the fire nozzle to ignite the fuel mixture for burning purposes.
