A fastener driver includes a housing, a magazine coupled to the housing containing fasteners therein, and a nosepiece at least partially defining a fastener driving track into which fasteners from the magazine are individually received. A driver blade is movable from a retracted position toward an extended position during which a fastener in the fastener driving track is discharged from an opening in the nosepiece. A work accessory including a guide portion is configured to align an article with the nosepiece opening prior to attaching the article to a workpiece during a fastener driving operation, and a separate puller portion configured to apply a tensile force to an article to be attached to a workpiece during a fastener driving operation. The work accessory is adjustable relative to the nosepiece to selectively position the guide portion or the puller portion proximate the nosepiece opening.

Electrically powered fastening devices configured to drive staples suited to multiple applications. The fastening device includes an adjustable feeder and depth gauge, a hammer device with a mechanism for translating rotary power to linear striking force, and a staple guide configured to drive staples with selected, specialized profiles and configured with inner radii sized and shaped to conform to particular wire and sheathing diameters.

The present invention provides a multifunctional stapler including a housing, a nailing portion arranged at a front end of the housing, and a toggling device, a part of which being arranged inside the housing and a part of which extending to the outside of the housing. The nailing portion comprises: a staple feeding member arranged at a front end of the bottom of the housing, a staple feeding groove arranged on the surface at one side of the staple feeding member for receiving staples, a striking member, a part of which being inserted into the staple feeding groove, the toggling device controlling the striking member to strike the staples, and an adjusting device, a part of which being arranged outside the housing, for adjusting a depth of the staple feeding groove.

Tool-free adjustment members in a fastener driving tool. The fastener driving tool can be used to seal closed containers such as, for example, corrugated fiberboard cartons, by applying staples to the folded flaps or other closure parts to secure them in place. The tool-free adjustment members provide customizable drive settings for a variety of different sized staples and different workpiece conditions.

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.

A stapler guiding structure is provided, adapted for being disposed on a stapler, the stapler including a main body, the stapler guiding structure including: a magazine assembly, configured to be disposed on the main body and configured to receive a staple unit, including a staple outlet and a stopper member close to the staple outlet, the staple outlet being configured for a staple of the staple unit to pass therethrough; a grooved unit, configured to be disposed on the main body and facing the staple outlet, including at least one groove, each groove including a guiding surface which extends along a guiding path, the guiding surface being configured to bend a leg of the staple which passes through the staple outlet, the guiding path being directed toward the stopper member.

The 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 a lower portion of a front end thereof A longitudinal direction is defined by the front end and a rear end of the main body. The magazine is arranged in the main body to receive staples. The striker is arranged at the front end of the main body and is movable linearly above the opening of the main body. The driving portion is arranged in the main body and is connected to the striker. The driving portion drives the striker to move downward to strike a staple out. The striker has a bottom end which is recessed and has two ends and an intermediate portion between the two ends. The intermediate portion is more recessed than the two ends.

A powered fastener driver includes a magazine configured to receive fasteners, a pusher slidably coupled to the magazine, a nosepiece coupled to the magazine, and a workpiece contact element movable with respect to the nosepiece. The powered fastener driver further includes a lockout member pivotally coupled to the nosepiece, and a magnet exerting a magnetic force on the lockout member to bias the lockout member toward a first position. The pusher moves the lockout member to a second position where the lockout member blocks movement of the workpiece contact element when a predetermined number of fasteners remain in the magazine.

A staple gun includes: a casing having a front blocking surface; a magazine disposed in the casing; and a staple delivery element and a resilient element disposed at the magazine. The magazine includes at least a staple cutting portion each having a top surface, a front end surface, and a guiding surface connected between the top surface and the front end surface. The front end surface and the guiding surface face the front blocking surface. A clearance for passing staples is disposed between the front end surface and the front blocking surface. The staple delivery element pushes staples in the magazine in a staple delivering direction. The resilient element enables staples to push the front end surface and the guiding surface of the staple cutting portion of the magazine, such that the magazine moves relative to the casing in a clearance adjustment direction opposite to the staple delivering direction.

A fastener driving machine according to one embodiment includes an ejection unit housing a fastener, and a driver blade configured to strike the fastener housed in the ejection unit. The ejection unit has a blade guide forming one side of an ejection path to which the fastener is supplied, a guide plate facing the blade guide and forming the other side of the ejection path, and a raised portion provided on the blade guide. The driver blade includes a recessed portion configured to receive the raised portion. The raised portion is positioned at the side of the fastener supplied to the ejection path, and suppresses entirety or part of the fastener from coming off the ejection path.
