Abstract
A compression tacker for driving fasteners includes a frame defining a nose portion and a grip portion. A front jaw is pivotally and removably mounted on the nose portion to define a drive track. A plunger is reciprocated in the drive track. The front jaw includes a locking mechanism that upon actuation by the operator of the tool, unlocks the jaw from the frame and allows it to be pivoted relative to the frame to expose the drive track. A handle for actuating the plunger is mounted on the frame and includes a bearing about which a spring is mounted. A workpiece engaging jaw may be removably fastened to the nose portion. The workpiece jaw includes upper and lower surfaces for engaging different workpieces.
