A nail gun includes a fastener drive track capable of receiving fasteners having different length. A faster positioning assembly includes at least one swinging member and a stop portion. The swinging member is elastically and pivotably disposed at a side of the fastener drive track. The stop portion is formed at an end of the swinging member and received in the fastener drive track. The stop portion is configured for positioning fasteners prior to the fasteners are hit, and the stop portion retractably exits from the fastener drive track when a long fastener is received in the fastener drive track. The fastener positioning assembly enables the nail gun to drive fasteners having different length, as such, it is very convenient to use such nail gun to join different workpiece having different thickness on an object.

A nail gun includes a housing defining a group of receiving grooves and a safety rod. The control valve includes a body and a valve stem slidably received in the body. The body is movably mounted in the receiving grooves and one end of the valve stem is arranged to sustain the safety rod at a predetermined height. The predetermined height can be adjusted by moving the body relative to the receiving grooves.

A locking mechanism for a nail gun includes a side slot formed on a bottom side of a gun body and a nail supplying slot connected to a drive track of the nail gun. A stopper element is formed on a side of a slider element corresponding to the side slot. The gun also includes a magazine in which a nail pusher facing the nail supplying slot and a lockout element facing the side slot are formed. The nail pusher has an ear portion. The lockout element includes a pushing arm and a moveable guide slot capping with the ear portion to restrict the sliding movement of the lockout element on the nail pusher. As the pushing arm extends towards the corresponding end of the nail supplying slot, a nail is pushed into the drive track to shoot. The lockout element enters into the side slot to block the stopper element when the nail is exhausted, so as to enhance the shooting blocking effect of the nail gun.

An improved pneumatic device includes a body having a hollow cavity, defining an X axis and having a first end and a second end. The body includes a movable cylinder, a nail-firing piston rod and at least one exhaust hole. The movable cylinder and the nail-firing piston rod reciprocate along the X axis in the body by performing a forward stroke to the second end, and a return stroke back to the first end. The movable cylinder presents an open status when completing the forward stroke and presents a closed status when completing the return stroke. The movable cylinder has an exhaust hole and an exhaust valve disposed at an outer periphery thereof. When the nail-firing piston rod has not completed the return stroke yet and the cylinder is in the closed status, an exhaust channel is thereby formed to facilitate exhausting of air.

A trigger valve controlling device for a pneumatic nail gun includes a main air passageway, a valve sleeve and a main air valve opening. The valve sleeve separates the main air passageway into a front passageway, a middle chamber and a rear passageway. After hitting nails, a high pressure air in the trigger valve controlling device is capable of driving a hitting bar of the pneumatic nail gun to move upward to reset.

A braking mechanism for empty nail cartridge of a nail gun includes a guiding plate, a cover plate, a punch rod, a securing slide rod and a nail cartridge. A nail hole and an end hole are defined in the guiding plate having a connecting groove. A nail pusher and a pushing arm are arranged in the nail cartridge to provide resilient force along a nail firing direction. The pushing arm is pivotably placed on the nail pusher adjacent the brake portion for affording the resilient force. The pushing arm allows the brake portion of the nail pusher to go through the end hole and move into the end hole to block the stopper of the securing sliding rod when the nails are used up. The pushing arm moves into the connecting groove to improve the yield rate of the brake of the empty nail cartridge of the nail gun.

A nail positioning member of a nail slot of a nail gun includes a magazine including a horizontal nail slot connected with a perforation for nailing; a nail pushing piece slidably assembled to the nail slot; a plurality of horizontal slot channels parallel to the nail slot; and a plurality of positioning pieces, respectively pivotally assembled to the slot channels to block the head of the nails. The positioning piece forms a protruding portion in a movement path of the nail pushing piece, to be pushed by the nail pushing piece and to drive the positioning piece to oscillate in the direction of the slot channel in order to open the nail slot for placing the nails.
