A tool includes a mechanical energy storage such as a helical spring, and an ejecting device to be linearly moved between a clamping position and an ejecting position. The ejecting device has a driver element and a shooting device, and an electric motor and a spindle drive driven by the electric motor converts a rotational movement of the electric motor into a linear movement of the ejecting device. A control device controls the rotation of the electric motor, and the ejecting device can move toward the clamping position by rotation of the spindle drive in a first direction of rotation. A locking device can lock the shooting device in the clamping position, and the shooting device can be released and moved toward the ejecting position by actuating the locking device. The driver element can be moved toward the ejecting position by rotating the spindle drive in a second direction.

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 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.
