Abstract: A pneumatic pallet nailer includes a nailer body, a trigger member, a pallet clamp controlling member, a pallet clamp cylinder and a pallet clamp. The trigger member is disposed on the nailer body. The pallet clamp controlling member is disposed on the nailer body and includes an internal space, a first pipe, a second pipe, a third pipe and an actuating valve. The air in the nailer body is communicated with the internal space by the first pipe and the second pipe. The third pipe is communicated with the internal space. The actuating valve is movably disposed in the internal space, and the actuating valve is actuated and positioned at a first position or a second position. The pallet clamp cylinder is communicated to the third pipe. When the trigger member is pressed, the pallet clamp is actuated by the pallet clamp cylinder to clamp a workpiece.

Abstract: An air source controlling device for a pneumatic nail-gun includes a body, a choke valve and a switch. The body includes a controlling chamber for connecting a compressed air source, an air passage for communicating the controlling chamber and the pneumatic nail-gun, a switch channel communicating the air passage and an accommodation space, and an air vent hole communicating the accommodation space and an external environment. The choke valve is disposed in the controlling chamber and is switchable between a communicating status and a non-communicating status for controlling the opening or closing between the controlling chamber and the air passage. The switch includes an actuating member slidably disposed in the switch channel and the accommodation space without covering the air vent hole. A sealing member is disposed on the actuating member and is sealed with the switch channel. The actuating member activates the choke valve.

Abstract: A fastener gun capable of preventing accidental discharging includes a gun body, a safety unit and a fastener magazine. The gun body has a firing channel and the safety unit is disposed adjacent the firing channel. The fastener magazine is utilized to guide a fastener strip. The fastener gun further includes a connecting portion and a stopping bar. The stopping bar is disposing on the connecting portion and capable of moving between a first position and a second position. The stopping bar has a pushing portion and a stop portion. The pushing portion may be optionally pushed by the fastener strip. When the stopping bar locates at the first position, the stop portion stops the movement of the safety unit. When the stopping bar locates at the second position, the stop portion does not stop the movement of the safety unit.

Abstract: An anti-separating mechanism for preventing a fastener strip from separating from a fastener gun is disclosed. The anti-separating mechanism is disposed in the fastener gun. The fastener gun includes a gun body, a fastener magazine and a feed member. The gun body includes a firing channel to receive a fastener. The fastener magazine is connected to the firing channel and is utilized to guide the fastener strip including a plurality of fasteners. The feed member is utilized to push the fastener strip in a first to direction toward the firing channel. The anti-separating mechanism includes a lever pivotally disposed on the fastener magazine. The lever swings between a stop position and a release position. The lever includes a stop surface, a withstanding portion and a tapered pushing surface. The tapered pushing surface is farther from the firing channel than the stop surface.

Abstract: A pneumatic nail gun includes a nail-gun main body, a first trigger, an auxiliary handle, an insurance unit, and an auxiliary insurance mechanism. The first trigger is disposed in the nail-gun main body. The auxiliary handle is extended from the nail-gun main body. The insurance unit is disposed at a nail outlet of the nail-gun main body and being capable of shifting between a non-firing location and a location to be fired. The auxiliary insurance mechanism includes a second trigger and an insurance stopper element. The second trigger is disposed on the auxiliary handle. The insurance stopper element is disposed in the nail-gun main body. The insurance stopper element is capable of shifting between a first location and a second location as controlled by operation of the second trigger so as to selectively block a shifting path of the insurance unit.

Abstract: An air source controlling device for a pneumatic nail-gun includes a body, a choke valve and a switch. The body includes a controlling chamber for connecting a compressed air source, an air passage for communicating the controlling chamber and the pneumatic nail-gun, a switch channel communicating the air passage and an accommodation space, and an air vent hole communicating the accommodation space and an external environment. The choke valve is disposed in the controlling chamber and is switchable between a communicating status and a non-communicating status for controlling the opening or closing between the controlling chamber and the air passage. The switch includes an actuating member slidably disposed in the switch channel and the accommodation space without covering the air vent hole. A sealing member is disposed on the actuating member and is sealed with the switch channel. The actuating member activates the choke valve.
