摘要:
A fastener driving tool (2) includes a housing (4), a drive track (20) within the housing, a magazine (10) connected to the housing and configured to hold a supply of fasteners and to provide a leading fastener to the drive track, a driver (23) configured to move downward in the drive track and drive the leading fastener into a workpiece (W) during a drive stroke, a mount connected to the driver, and a clincher (40) operatively connected to the housing and to the mount. The clincher is configured to engage the leading fastener during the drive stroke and move into a clinching position at the end of the drive stroke to clinch the fastener to the workpiece. A motor (26) is configured to rotate a crank arm, and a connecting rod is pivotably connected to the mount at one end portion thereof and pivotably connected to the crank arm at an opposite end portion thereof.

In an embodiment of the present invention, a reinforcement bar fastener (rebar fastener) has a substantially T -shaped body with an upper horizontal portion that forms a crossbar between and is integral with a lower pair of legs. In an embodiment of the present invention, there is a fastening tool for applying a driving force to the reinforcement bar fastener to bend the fastener around rebar members to secure the rebar members to each other. The fastening tool can have a body including a driver that provides a downward force on the crossbar portion of the rebar fastener while retractable anvil arms bend the lower vertical leg portions of the rebar fastener upward around the arranged rebar members.

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.

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).
摘要:
A fastener driving device includes a nose assembly carried by a housing that has a reservoir. The nose assembly has a fastener drive track. At least a portion of the fastener drive track is defined by a movable portion of the nose assembly. A fastener driver is movably mounted in the housing and configured to enter the drive track and drive successive leading fasteners into a workpiece. A head valve is constructed and arranged to be actuated so as to allow the pressurized gas to move the fastener driver through an operating cycle. An actuator is constructed and arranged to actuate the head valve. The actuator includes a trigger valve constructed and arranged to allow passage of the pressurized gas from the reservoir to a chamber above the head valve, and a contact valve operatively connected to the movable portion of the nose assembly.
