A fastener magazine for a fastener driving tool has a movable guide that allows fasteners of various lengths to be loaded in the magazine. When engaged, the movable guide sequentially directs each fastener's movement during a drive stroke. When disengaged, the movable guide does not interfere with each fastener's movement during a drive stroke. In the engaged position, the movable guide prevents a fastener from complete “backtracking” back into the magazine during a drive stoke, which otherwise could potentially cause a jam condition.

A fastening tool including a magazine securely and releasably retained on the fastening tool by a cam mounted on one of the fastening tool and the magazine. In a single rotary motion, the cam wedges together the housing member of the fastening tool and the housing member of the magazine, while simultaneously rotating cam lobes into respective chambers formed on the fastening tool and the magazine. The cam rotation and magazine retention system is accomplished without tools.

A fastener driver includes a pusher assembly slidably coupled to a magazine assembly. The pusher assembly includes a first portion and a second portion that are selectively movable relative to each other. The pusher assembly is adjustable between a first state in which the first portion and the second portion are configured to move together in unison toward the channel, and a second state in which the first portion moves relative to the second portion toward the channel. A dry-fire lockout assembly includes a blocking member coupled to the magazine assembly or the nosepiece assembly, and a lockout member selectively engageable with the blocking member for moving the blocking member from a first position and a second position. The pusher assembly is configured to transition from the first state to the second state after a predetermined number of fasteners remain in the magazine assembly.

Various embodiments of the present disclosure provide a battery-powered stapling tool. In one embodiment, the stapling tool includes a drive wheel, a cam drivable by the drive wheel in a first rotational direction from a first position to a second position and back to the first position to carry out a staple-driving process, a motor operably connected to the drive wheel to drive the drive wheel, a lifting element defining a slide in which the cam is received, and an ejector connected to the lifting element and drivable by the lifting element between an ejector home position and an ejector ejection position. The slide has first and second slide segments that are transverse to one another. The lifting element is movable between a lifting-element home position and a lifting-element ejection position.

A fastening tool having a nail stop which positions a nail for driving and is made at least in part of a contact material which can be investment cast and/or hardened. The contact material can resist wear from the action of driving the nail and the movement of a driver blade. The nail stop can be configured to align nails fed from a magazine and can be offset from the longitudinal centerline of the fastening tool. The nail stop can have a head contact length which is 0.5% to 95% of the length of the nail to be driven. The nail stop is used in methods for positioning a nail for driving.

A magazine for use with a fastening tool. The magazine can have a pusher assembly that can be retracted into a recess in the magazine to facilitate loading and reloading of fasteners. The pusher assembly can have a pusher assembly knob which can be reversibly latched to a detent to maintain the pusher assembly in a retracted state. The fastening tool can use a magazine which can be reloaded by a method which has a step of reversibly retracting the pusher assembly into the retracted state to allow for feeding one or more fasteners to the magazine.

A nailing unit comprising a nail box, a nail magazine, a nail pushing block, a tail buckle switch, a nail limiting block fit together with a nail guiding plate through slits is provided. The nail magazine includes a heat-treated guide rail assembly mounted with a nail splitting plate at the end near the nail guiding plate; the nail pushing block which is connected to a spring is formed with three nail pushing feet adapted to a first, second, and third gaps; the nail guiding plate includes two connecting wings and forms a low-lying guide plate therebetween; each angle between the guide plate and each connecting wing is respectively fixedly provided with a positioning step along the longitudinal direction.

The nailing unit fulfills efficient nailing for T nails, straight nails, and different types of code nails and U nails, and prolongs the service life of the nail gun.

A fastener driving device includes a housing assembly, a nose assembly connected to the housing assembly, a magazine for carrying a supply of fasteners through a feed channel along a feed direction toward the nose assembly, and a plurality of stop pawls independently movable about a common pivot axis. Each stop pawl has a distal end extending into the feed channel.

A pneumatic fastener driver operable in a single sequential mode and a bump-fire mode, and includes a housing, a nosepiece, a trigger moveable between a default position and a depressed position, a contact arm movable relative to the nosepiece between an extended position and a retracted position, and a timeout mechanism operable in the bump-fire mode to inhibit the drive cycle from being initiated in response to inactivity of the contact arm over a preset time interval defined by unwinding of a mainspring that is initially wound in response to the trigger being actuated from the default position to the depressed position. The pneumatic fastener driver also includes a counting assembly having a female barrel pivotably coupled to a pivot shaft of the trigger and driven by the mainspring and a lockout linkage coupled to the female barrel that is capable of interfering with a portion of the trigger.
