Abstract:

A self-adjusting cable guide can be coupled to a nosepiece assembly having a contact end and can be movable between an extended guide position and a retracted guide position relative to the contact end of the nosepiece assembly. A contact trip arm can be adjacent the cable guide and can have a distal end positioned to contact a cable received within a guide recess of the cable guide. The contact trip arm can be movable between an extended arm position corresponding to an inactive state of the tool and a retracted arm position corresponding to an active state of the tool. In addition, the cable guide can have a non-aligned orientation, in which cooperating misalignment stop surfaces can engage each other to stop movement of the self-adjusting cable guide toward the retracted guide position and an aligned orientation in which movement into the retracted guide position is permitted.

Abstract:

A fastening tool includes an actuation device configured to actuate a drive engine of the tool to initiate a drive stroke. The actuation device includes a contact trip assembly operatively connected to the movable portion of the nose assembly. The contact trip assembly a lower contact arm connected to the movable portion of the nose assembly biased in the retracted position and movable to the extended position with the moveable portion of the nose assembly, and an upper contact arm operatively connected to the lower contact arm. The actuation device includes a trigger assembly that includes a trigger, a trigger arm pivotally supported by the trigger and configured to interact with the upper contact arm, and a check pawl configured to engage an opening in the upper contact arm when the upper contact arm moves downward to prevent the tool from being operated in a contact trip mode.
