Abstract: A burner gun includes a case, an ignition device, a switch and a operational part. By the switch and an operation rail in the case, the ignition device can only be activated by correctly operating the switch and pulling the operational part. The ignition device cannot activated by pulling the operational part if the switch is not correctly operated, so that the ignition device is prevented from being activated unintentionally to reduce possibility of causing fire disasters.

Abstract: A safety device for a gas burner includes an ignition-gas unit and a lever is pivotably connected to the installation port. The lever extends beyond a cover on the ignition-gas unit and includes a free end to which a restriction member and a spring are connected. The spring drives the restriction member toward the cover to restrict the lever from being pushed to ignite the gas burner. When the restriction member is moved, the user can push the free end downward to activate the ignition-gas unit to ignite the gas burner.

Abstract: The present invention discloses a safety switch for a portable stove, which controls the startup of an ignitor as well as an adjusting rod to adjust the flame. By latching an end of a push button into a limit groove disposed above an installing hole, the invention assures the stove to be turned off completely to prevent a fuel leak. With a gap between the push button and the installing hole, a knob can be turned to drive the adjusting rod to adjust the quantity of incoming airflow of the fuel. If a pressing rod is pressed to start the ignitor, the knob and the push button will not move back and forth accordingly, so that the push button will not be worn out so easily but can maintain its longevity.

Abstract: This invention discloses a heat control device of a portable gas stove, comprising a hollow cylindrical button base and a switch button, an installing slot protruded from the top of the inner wall of the button base, a spring disposed in the installing slot, and a pressing member with its rear end being installed in a limit notch at the open end of the button base for mutual engagement. The pressing member is completely latched into the limit notch to ensure a complete shutdown of the gas supply.

Abstract: A device for fastening a barrel of a gas operated soldering gun to a spout of a combustion chamber thereof is disclosed. The device comprises a cavity in a rear end of the barrel, a resilient clip disposed in the cavity, and a plurality of latched pieces on the clip, the latched pieces being disposed inside the clip. The spout can be fastened in the barrel by clinging the barrel to the spout as the latched pieces exert a strong, resilient force onto the spout. The invention can carry out a quick assembly or disassembly of the barrel and the spout and increase soldering efficiency and safety.

Abstract: A gas burned soldering tool provided with a swivel flame extinguisher controlled to extinguish open flame. The swivel flame extinguisher includes a fixed locating rod, a shaft, a control knob and a stopper respectively and perpendicularly extended from two opposite ends of the shaft, and a torsional spring mounted around the shaft, the control knob having a projecting rod, the torsional spring having one end connected to the projecting rod of the control knob and an opposite end fastened to the locating rod, the stopper being turned with the shaft by means of the control of the control knob between a first position where fuel gas is allowed to pass out of the gas nozzle and a second position wherein fuel gas is stopped from escaping out of the gas nozzle.
