Various embodiments of the present disclosure provide a combustion-powered fastener driving tool fuel cell assembly including a fuel cell, fuel cell adapter, and fuel cell adapter cap for a combustion-powered fastener driving tool. The fuel cell, the fuel cell adapter, and the fuel cell adapter cap enable both the fuel cell adapter and the fuel cell adapter cap to be attached to a fuel cell and particularly a sealing member of the fuel cell in one efficient step. This single step process can be done manually or automatically, and is substantially more efficient and less time-consuming than the known fuel cell assemblies.

A locomotive (10) for spreading a waterproof coil in a hot melt manner. The locomotive (10) for spreading a waterproof coil in a hot melt manner comprises: a locomotive frame (11), provided with a coil support (12); and wheel devices, a spreading device, a combustion and heating device and a coil compaction device that are disposed on the locomotive frame (11). The combustion and heating device comprises a combustion chamber (6) and a mixing chamber (2). The mixing chamber (2) is provided with a fuel gas inlet end (5), an air inlet end (28), and an outlet end (29). The outlet end (29) is connected to the combustion chamber (6). Multiple gas discharge holes (7) are formed in one side surface of the combustion chamber (6) in an axial direction. The locomotive (10) for spreading a waterproof coil in a hot melt manner improves the construction efficiency, reduces human power costs and reduces consumption of fuel gas.

A burner device includes a fuel tank and an ignition unit. The fuel tank includes a chamber, a first thread portion, and a check valve including a valve body. The ignition unit removably attached to the fuel tank. The ignition unit includes a second connecting portion engageable with the first thread portion, and a top pillar selectively to push against the valve body of the check valve to slide along a longitudinal axis. When the fuel in the fuel tank is depleted during the operation, a user can use a filling assembly to fill the supplemental fuel into the fuel tank or replace another fuel tank instantly to improve convenience.

A handheld welding torch apparatus for welding in confined areas includes a gas tank having a handle portion and an extension portion. Each of the handle portion and the extension portion is cylindrical. A valve assembly is coupled to the gas tank and comprises a tank receiver, a tube stem, a valve housing, and a control valve. The tube stem is coupled to the tank receiver. The tube stem is in fluid communication with the gas tank when the tank receiver is engaged with the extension portion. The valve housing is coupled to, and in fluid communication with, the tube stem. The control valve is coupled within, and in fluid communication with, the valve housing. A tube neck is coupled to, and in fluid communication with, the control valve. A welding tip is coupled to the tube neck.

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.

The present invention provides a gas combustor having detachable combustion device, which includes: a housing having the interior installed with a base, and a combustion device. When the combustion device is inserted in an insertion slot of the housing, the upstream end of a mix pipe of the combustion device is airtightly inserted in a sleeve opening of the base, and a pair of locking sheets of the combustion device are moved along a pair of stopping protrusions of the housing and cross the pair of stopping protrusions, so a first spring between a lock button and a positioning seat of the combustion device is allowed to respectively be compressed for storing energy or stretched for releasing energy, and the pair of locking sheets are enabled to be abutted against inner edges of the pair of stopping protrusions, so an interference is generated for forming a locking and combining status.
