A nail gun is provided with a wide and narrow nail switching and nail blocking structure provided with a nail rail. The nail gun includes a punching sheet guide rail vertically arranged in front of the nail rail, the punching sheet guide rail defining a positioning groove. One side of the positioning groove extends upwards to form a groove A in which a regulating block is arranged in a sliding manner, and another side of the positioning groove extends downwards to form a groove B in which a nail blocking bar is rotatably arranged through a pin shaft, wherein the nail blocking bar is capable of rotating between an initial position and a terminating position around the pin shaft. A spring sheet presses against the nail blocking bar. A toggle button is vertically arranged in front of the regulating block to selectively clamp and press against the regulating block.

A fastener driver including a main housing, a drive blade movable from a retracted position to a driven position for driving a fastener into a workpiece, and a gas spring mechanism for driving the drive blade from the retracted position to the driven position. The gas spring mechanism includes a cylinder housing containing a pressurized gas, and a piston movable relative to the cylinder housing and biased by the pressurized gas from a retracted position toward a driven position. The cylinder housing is displaceable along a longitudinal axis of the piston relative to the main housing and away from the drive blade, while the piston remains stationary relative to the main housing, to reduce the pressure of the pressurized gas within the cylinder housing.

A pneumatic fastening tool that has an integrated valve assembly. The integrated valve assembly can have a cylindrical valve assembly housing that can house a portion of a head valve assembly and can also house at least a portion of a trigger valve assembly. The head valve assembly can have a head valve body that can be maintained in a resting state by compressed air. The compressed air that maintains the resting stat of the head valve assembly can be provided by one or more passages formed in the valve assembly housing. The valve assembly housing can also guide the movement of the valve head body when the trigger valve assembly is actuated causing a fastener to be driven into a workpiece. The valve assembly housing can have a circular exhaust seal and a cylindrical exhaust chamber through which compressed air can be exhausted after the driving of a fastener into a work piece.

A staple insertion device includes a staple drive chamber, staple reservoir, staple feed mechanism, and staple drive member. The staple drive chamber is formed between a backing plate and a jam plate removably attached to the backing plate. The staple reservoir is configured to receive and hold a plurality of staples and extends from the backing plate to a staple reservoir terminal plate. The staple feed mechanism is operatively connected to the staple reservoir and is configured to feed the plurality of staples from the staple reservoir into the staple drive chamber through the backing plate. The staple drive member is configured to advance downwardly through the staple drive chamber so as to drive a staple out of the staple drive chamber.

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.

The present invention relates to a nail driving tool, in particular a compressed air nailer, with a main body (2), which comprises a running tube (3) for guiding a nail to be driven into a workpiece and a firing pin driving the nail, the running tube (3) extending between a front free end (4), where the nail exits as it is driven into a workpiece, and a drive-side rear end. The invention also relates to a movable guide element (17) and to a stationary guide element (42), which can be mounted selectively to the nail driving tool.

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.

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 located at a first end of the magazine, a loading portion located at a second end of the magazine, and a feed channel extending lengthwise through the magazine between. The loading portion of the magazine includes first and second slots configured to receive fasteners of the corresponding first and second lengths for entry into the feed channel, and a feed channel access gate configured to prevent fasteners of the first length from being loaded into the second slot. The feed channel access gate is configured as a pivot member pivotable about an axis between a first, blocking position, and a second, bypass position. A spring biases the feed channel access gate toward the blocking position.

A fastener driver including a main housing, a drive blade movable from a retracted position to a driven position for driving a fastener into a workpiece, and a gas spring mechanism for driving the drive blade from the retracted position to the driven position. The gas spring mechanism includes a cylinder housing containing a pressurized gas, and a piston movable relative to the cylinder housing and biased by the pressurized gas from a retracted position toward a driven position. The cylinder housing is displaceable along a longitudinal axis of the piston relative to the main housing and away from the drive blade, while the piston remains stationary relative to the main housing, to reduce the pressure of the pressurized gas within the cylinder housing.

A stapler includes a main body, a magazine, a striker, and a driving portion. The main body encloses a receiving space and has an opening at the bottom of the front end thereof. The opening communicates with the receiving space. The magazine is arranged in the main body for receiving staples. The striker is arranged at the front end of the main body and is linearly slidable above the opening vertically. The driving portion is disposed on the main body and is connected to the striker to drive it to move downward to strike the staple out. The striker has a bottom face oriented frontward and downward so that an angle ranged from 3-15 degrees is defined between the bottom face and the horizontal plane.
