The invention provides a pneumatic nail gun, comprising a gun body, a nail box, a fork and a nail forming device. The gun body comprises a sliding groove, a nail outlet adjacent to the sliding groove and a push block. The nail box and the fork are fixed on the gun body. The nail box is configured to place a plurality of strip nails to be sequentially exposed from the nail outlet. The formed fork comprises two forming surfaces with unequal heights, and the two forming surfaces are adjacent to the nail outlet. The nail forming device comprises two jaw arms, two control arms and a push seat, and the push block drives the two control arms to drive the two jaw arms to rotate and close the two forming jaws, and to drive the push seat to slide on the sliding groove.

Various embodiments of the present disclosure provide a battery-powered stapling tool.

A nailer device for collated nails (S) can be loaded with an elongated strip (E) almost flat shaped and provided with at least a plurality of first connections (P) projecting therefrom and each provided with a fixing end (F) opposite to the elongated strip (E) and assigned to the removable fixing of a respective nail (N) of collated nails. The device (1) includes a sliding seat (9) aligned with a magazine (3) and in communication with a shot chamber (5) that receives the elongated strip (E). Thrusting means (13) is provided with a matching means (15) assigned to match with the fixing end (F) of the first connection (P) previously bearing a fired nail in a stroke of the thrusting means from an external extreme condition to an extreme internal condition to align the first connection (P) of such fixing end (F) to a portion of the sliding seat.

A device for driving fastening elements into a substrate comprises a setting channel; an energy transmission element, which can be moved in a fastening direction in the setting channel, for transmitting energy to one of the fastening elements at a time; and a magazine for transporting the fastening elements to the setting channel in a transport direction. The magazine is suitable for transporting multiple rows of fastening elements at once. Additionally, a fastening element strip comprises a plurality of rows of receptacles for fastening elements aligned in a transport direction and fastening elements which are housed in the receptacles and define a fastening direction, wherein the rows of receptacles are arranged one behind the other in a transverse direction oriented perpendicular to the transport direction and perpendicular to the fastening direction.

A flywheel-driven setting device comprises a flywheel which can be drivingly connected to a driving element in order for a setting element to be driven into a substrate by means of the driving element during a setting process. The flywheel is subdivided into at least two flywheel parts which are movable relative to each other to a limited degree in the axial direction.

A powered fastener driver including a driver blade movable from a top-dead-center position to a bottom-dead-center position for driving a fastener into a workpiece. A driver may include a lifting assembly for providing torque to move the driver blade from the bottom-dead-center position toward the top-dead-center position, the lifting assembly including a rotary lifter configured to be selectively engageable with the driver blade, the rotary lifter having a plurality of lift pins and a roller disposed on at least one of the lift pins, wherein the roller includes a plurality of cam portions defined by cup-shaped recesses having a first radius oriented parallel to a rotational direction of the roller and a second radius perpendicular to the first radius, and wherein the driver blade includes a lift tooth having a crown disposed thereon, the crown configured to be engaged with at least one of the plurality of cam portions.

Various embodiments of the present disclosure provide a portable battery-operated stapler.

A nail gun includes: a housing; an accessory box for accommodating a fastener and at least partially connected to the housing; and a power output portion for outputting a striking force to the fastener; and an operating member triggered to have at least a first position and a second position, where the nail gun has a maximum desired penetration depth when the operating member is operated to the first position, and the nail gun has a minimum desired penetration depth when the operating member is operated to the second position; and when the operating member switches from the first position to the second position, an angle by which the operating member rotates about a first straight line is less than or equal to 360?.

A fastening tool having a magazine pusher position detection system that informs the tool of a dry fire state due to less than a predetermined number of fasteners in the magazine assembly. The magazine pusher position detection system includes a sensor and a sensor target having a characteristic that is sensed by the sensor. When the characteristic is interrupted by an external member on the pusher, the sensor sends a signal to the controller indicative of a low nail or a low fastener condition. This can be done magnetically or optically. The controller then initiates a dry fire lockout that prevents the tool from driving a fastener, and actuates an indicator that notifies the user of a low nail or low fastener condition.

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.
