摘要:
A fastener driving device (10) includes a frame, a fastener driver (33) reciprocally mounted in the frame, and a trigger assembly (39). The trigger assembly (39) includes a trigger lever (51) configured to be moved to an actuated position to actuate the fastener driving device (10), a mode selector (60) rotatably mounted to the frame, the mode selector (60) being configured to move to select a mode of operation of the fastener driving device (10), and a trigger lock (64) mounted to the frame, the trigger lock (64) being movable between a first position wherein actuation of the trigger lever (51) is permitted and a second position wherein actuation of the trigger lever (51) is prevented. In the first position, the trigger lock (64) engages the mode selector (60) to prevent the mode selector (60) from moving. In the second position, the trigger lock (64) disengages the mode selector (60) to permit movement of the mode selector (60) to select the mode of operation of the fastener driving device (10).

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.
