A binding machine, includes: a staple magazine unit configured to accommodate a staple having a crown portion and a pair of leg portions; a staple driver provided at a position facing the crown portion; a clincher provided at a position facing tip ends of the leg portions and movable along an extending direction of the leg portions; and a regulating portion configured to regulate a movement amount of the clincher toward the leg portions. The clincher and the staple driver are configured to sandwich the staple therebetween with a movement of the clincher along the extending direction toward the leg portions, folding the staple.

A fastener cartridge assembly for use with a surgical end effector. The fastener cartridge assembly can comprise a cartridge body having fastener cavities, fasteners removably positioned in the fastener cavities, a layer of material releasably secured relative to the cartridge body, a connector configured to secure the layer of material to the cartridge body at a location distal to at least one fastener cavity, and an actuator. The layer of material can be a tissue thickness compensator. When actuated, the actuator can overcome the connector, and can overcome the connector prior to the removal of the fasteners from the fastener cavities. The actuator can be actuated at a location proximal to at least one fastener cavity, and can extend distally past at least one fastener cavity toward the connector.

A tool is provided for applying fasteners to a workpiece. The tool has a housing with a nosepiece, a motor, a drive actuator, a magazine assembly that holds fasteners, and a feed assembly with a feed actuator configured to move a lead fastener into the nosepiece. A driver in the housing is driven by a drive system that is associated with the driver actuator. A controller is connected to the feed actuator and the drive actuator to implement a firing sequence for driving each lead fastener into the workpiece using the driver and feeding the lead fastener into the nosepiece assembly. The actuators may be in the form of solenoids. The controller is designed to energize and deenergize the motor selectively while the drive actuator and feed actuator are activated.

A cap hammer for driving a staple through a cap into a work surface. The cap hammer includes a staple magazine configured to hold a plurality of staples, a cap magazine disposed beneath the staple magazine and configured to hold a horizontal stack of caps, an internal guide body disposed at a forward end of the cap hammer, a cap driver blade disposed within the internal guide body configured to shear a cap from the stack of caps, a staple driver blade disposed within the internal guide body configured to shear a staple from the plurality of staples, and a work contact element disposed at the forward end of the cap hammer and configured to activate the cap driver blade and the staple driver blade when depressed against a work surface.

A reload assembly includes a shell housing, a knife carrier, and a one-way collar. The knife carrier is movably positioned about an inner housing portion of the shell housing between retracted and advanced positions and supports a snap-ring. The one-way collar is movably supported about the inner housing portion of the shell housing from a retracted position to an advanced position in response to movement of the knife carrier from its retracted position to its advanced position. The snap-ring is movable with the knife carrier to a position proximally of the one-way collar when the one-way collar is in its advanced position to obstruct movement of the knife carrier back towards its advanced position.

A hammer tacker is provided, including a grip portion and a body portion; a magazine, including a rail, at least partially received in the housing, being movable relative to the housing between a stapling position and a staple-installing position, including an outlet disposed at a front end of the body portion; a biasing mechanism, including a push member movably mounted to the rail and a constant force spring which is rollable, the constant force spring being positionally attached to the rail through a connection portion and located at a front end of the magazine, and the constant force spring being attached to an inner face of the push member, the push member being movable to be correspondingly above or beyond the connection portion; a striking mechanism, mounted to the body portion and configured to strike at least one staple installed in the magazine.

A preferably pliers type stapler is disclosed with a staple loading structure that is both simplified and easy to operate. A lower handle and base are connected to the body through a pivoting and cam system. A single motion pulls the lower handle and base away from the body to expose a staple track location for loading staples at a bottom of the body. Preferably the same single motion releases the track to move outward from a rear of the body. In one embodiment a compact simplified structure using a preferably torsion spring provides a low cost reliable spring energized system.

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 battery-operated non pneumatic plier stapler for accurately and effectively applying staple fasteners onto a surface. The plier stapler includes a rechargeable battery pack secured into a battery slot for providing electric power to a driver piston assembly. The battery pack is removably mounted to the battery socket and can be replaced with another battery pack. The stapler further includes a laser sight to indicate precise staple placement during application, thereby enabling accurate stapling operation. A magazine stores staples and the staples are biased towards nose using springs and rollers. The clencher clutches legs of individual staples to finish the stapling process. The stapler is cordless and obviates the need to use air compressors to apply staples, thereby eliminating limits on movement, air supply, and other factors.

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.
