A stapler is provided, including: a main body, having a nail outlet and a cartridge, an opening of the cartridge communicating with the nail outlet; a nail guiding mechanism, including a guiding plate facing the opening and a biasing mechanism disposed between the main body and the guiding plate, the guiding plate having an upper end away from the nail outlet, the biasing mechanism abutting against the guiding plate and normally biasing the upper end toward the cartridge; a striker, movably disposed within the main body; an operable mechanism, movably connected to the main body, being operable to drive the striker to move toward the nail outlet.

A stapler is provided, including: a main body, having a front end and a rear end; a magazine, disposed in the main body having an outlet end; a striker, disposed in the main body and located between the front end and the outlet end along the longitudinal direction; a driving mechanism, connected to the striker to optionally drive the striker to strike the staple; a pressing element, located in the main body and between the striker and the outlet end along the longitudinal direction, the pressing element being movable between an original position and a pressed position, the original position being higher than the pressed position, the pressing element having a tendency to stay on the original position, when the pressing element is located on the pressed position, the pressing element presses the staples which are exposed outside the outlet end of the magazine.

A fastener driver includes a housing, a cylinder disposed within the housing, a piston positioned and moveable within the cylinder, and a driver blade. The driver blade includes a body defining a first end having an aperture defined therein, a second end opposite the first end, and a plurality of teeth between the first and second ends. The aperture is sized to receive a fastener to attach the driver blade to the piston. The driver blade is moveable with the piston from a first position toward a second position along a longitudinal axis during a fastener driving operation. A nosepiece at least partially defining a fastener driving track through which fasteners are driven. A total length of the fastener driver as measured between a distal end of the nosepiece and a distal end of the cylinder is less than 11.4 inches (289.6 mm).

A fastening tool assembly has a magazine body in a sleeve to convey fasteners to a housing outlet. Pivoting a lever relative to the housing, translates a knife to a loaded position, thereby disengaging from the knife, permitting a spring to return the knife to an unloaded position to drive a fastener through the outlet. A handle is pivotally connected to the housing. A roller is directly connected to the lever and the handle for permitting translation of the lever relative to the handle as the lever and the handle are pivoted relative to the housing. A spring-loaded bracket is operably connected to the magazine body for translation and rotation relative to the body. A latch is mounted to the housing to engage the bracket and maintain the magazine body in a retracted position, and is movable to a disengaged position wherein the bracket extends from the magazine body.

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.

The present disclosure discloses a stapling device, comprising an activation unit configured to sense at least one of a movement of the stapling device, a position of a switch or a signal from a timer. There is a detection unit that is activated based on a signal from the activation unit to generate an input data. The stapling device further comprises a processing unit to determine number of pins in the stapling device, by comparing the input data with a pre-configured data and a display unit interfaced with the processing unit, to indicate status of the pins in the stapling device, wherein the status is based on the determined number of pins in the stapling device. Thus the stapling device of the present disclosure identifies the exhaustion of pins and accordingly enables timely replenishment of the stapling device with pins.

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.

The present invention relates to a stapler for box edges which fixes edge portions of a box, presses an end of an iron core, and doubly pulls a handle bar so as to minimize protrusion of the end of the iron core. The stapler includes a load bar and a push plate which can locate an iron core on an iron core support plate when the handle bar is pulled first and presses the end portions of the iron core inward when the handle bar is pulled second.

A magazine assembly and a stapler including the same are provided. The magazine assembly includes a main body and a staple-pushing mechanism. The main body has a seat body and at least one rail, the seat body has a first end portion and a second end portion, a connection of the first and second end portions is defined as a moving path, and the at least one rail is disposed on the seat body. The staple-pushing mechanism is arranged on the main body, the staple-pushing mechanism includes a staple-pushing member and a constant force spring, and the staple-pushing member is driven to move toward the first end portion via the constant force spring.

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.
