摘要： A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, a driver blade attached to the piston and movable therewith between a ready position and a driven position, a lifter to move the driver blade from the driven position to the ready position, and a transmission including an output shaft operatively coupled to the lifter to provide torque to the lifter. The fastener driver also includes an input to provide torque to the transmission and a clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft and the lifter. In response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the input is diverted from the output shaft via the clutch.

摘要： A powered fastener driver includes a magazine in which fasteners of a first length or fasteners of a second length greater than the first length are receivable. The magazine includes a shear block, a loading portion, and a feed channel extending lengthwise through the magazine between the shear block and the loading portion. The loading portion includes a first slot and a second slot that are each configured to receive fasteners of the corresponding first and second lengths for entry into the feed channel. The loading portion also includes a pivot member configured to prevent fasteners of the first length from being loaded into the second slot corresponding to the fasteners of the second length. The pivot member is pivotable about a pivot axis between a first, blocking position blocking access to the second slot, and a second, bypass position permitting access to the second slot.

摘要： A powered fastener driver includes a housing, a nosepiece having a fastener driver channel from which fasteners are discharged into a workpiece, a driver blade, a workpiece contact element, and a pusher mechanism. The powered fastener driver also includes a dry-fire lockout mechanism having a lockout lever movable between a bypass position and a blocking position and a last fastener holding member configured to engage a fastener within the fastener driver channel. The lockout lever is configured to engage the fastener within the fastener driver channel. The last fastener holding member biases the fastener within the fastener driver channel toward an inner surface of the fastener driver channel to inhibit the fastener from falling out of the fastener driver channel.

摘要： A power tool includes a housing and a support arm extending from the housing and defining a longitudinal axis. The support arm includes a first arm portion coupled to the housing and a second arm portion coupled to the first arm portion. The power tool further includes a drive pulley coupled to the first arm portion. The drive pulley defines a first axis. A driven pulley is coupled to the second arm portion and defines a second axis spaced from the first axis. A synchronous belt connects the drive pulley and the driven pulley. The second arm portion is movable relative to the first arm portion between a first configuration and a second configuration offset 180 degrees from the first configuration about the longitudinal axis. A distance between the first axis and the second axis is substantially the same in both the first configuration and the second configuration.

摘要： A power tool includes a housing and a handle coupled to the housing. The handle is configured to be gripped by an operator to manipulate the power tool. The power tool also includes a drive system supported in one of the housing or the handle. The drive system includes a frame, a motor at least partially supported by the frame, and a transmission driven by the motor. The transmission is at least partially supported by the frame. The frame is composed of a non-electrically conductive material.

摘要： A powered fastener driver includes a housing, a nosepiece having a fastener driver channel from which fasteners are discharged into a workpiece, a driver blade, a workpiece contact element, a canister magazine, and a pusher mechanism coupled to the nosepiece. The powered fastener driver also includes a dry-fire lockout mechanism having a lockout lever movable between a bypass position and a blocking position and a last fastener holding member configured to engage a first side of a fastener within the fastener driver channel. The lockout lever is configured to engage an opposite, second side of the fastener within the fastener driver channel. The last fastener holding member biases the fastener within the fastener driver channel toward an inner surface of the fastener driver channel to inhibit the fastener from falling out of the fastener driver channel.

摘要： A powered staple driver includes a magazine configured to receive staples and a nosepiece having a staple driving channel from which consecutive staples from the magazine are driven, the staple driving channel extending along a driving axis. The magazine obliquely extends from the nosepiece in both a first plane containing the driving axis and a second plane that is perpendicular to the driving axis.
