A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.

A clinch staple mechanism including a pivoting base configured to be pivotally connected to a pneumatic stapling tool. The pneumatic stapling tool is configured to dispense staples each staple having a crown and a pair of staple legs, wherein the crown is disposed in a crown direction. The clinch staple mechanism further includes a clinch arm pivotally connected to the pivoting base at a proximal end of the clinch arm; and a clinch block disposed on a distal end of the clinch arm, wherein the clinch block is configured to bend the staple legs in a direction perpendicular to the crown direction.

A clinch fastener mechanism including a pivoting base configured to be pivotally connected to a pneumatic fastener tool. The clinch fastener mechanism further includes a clinch arm pivotally connected to the pivoting base at a proximal end of the clinch arm; and a clinch plate disposed on a distal end of the clinch arm, wherein tool operates within three pressure zones. The system may also include a two-valve system which works by moving pressure throughout three specific zones. The first pressure zone has pressure introduced to it by the user attaching the tool to a pressure delivery source, such as a compressor, or other source. The second pressure zone may be used to operate the clinch arm or a safety mechanism. Mechanical safeties may be configured to prevent accidental or double firing of the tool.

A switching device for a nail gun includes a trigger, a rod, a resilient member and an actuating member. The trigger includes a pair of slots each including first and second ends. Each of the first and second ends includes a small diameter portion, a large diameter portion and a shoulder portion disposed therebetween. The rod extends through the slots and includes a sliding portion and a positioning end having a diameter larger than that of the sliding portion. The movable rod is movable between an engaging position where the positioning end contacts a wall defining one of the first and second shoulder portions, and a disengaging position where the positioning end is disengaged from the one of the first and second shoulder portions.
