The fuel gas is ignited by means of the ignition means, and a wall rod abuts against a trigger rod. By pressing the retaining member, a fastening rod fastens the gas supply means in position to maintain supply of fuel gas. After use, the button member returns to its original position and is automatically retained by the press member.
