摘要： The present disclosure provides various embodiments of a fastener-driving tool that includes a battery-charged supercapacitor as a power source. The fastener-driving tool includes first and second spaced-apart, conductive rails and a partially conductive piston slidably mounted on the rails. The rails and the piston are electrically connected to one another. The supercapacitor is electrically connected to the first rail. When the supercapacitor discharges electrical current, the electrical current flows from the supercapacitor, into the first rail, through the piston into the second rail, and from the second rail. The electrical current induces magnetic fields in the rails and the piston, and the combination of the electrical current and the magnetic fields induce a Lorentz force that acts on the piston to move the piston toward a nosepiece to drive a fastener.

摘要： An electric power tool includes a motor, a lifter, a firing pin, an electromagnet, a driving circuit, a latch, and a controller. The lifter is driven by the motor to drive the firing pin to perform a firing action. The driving circuit provides electric current to excite the electromagnet. The latch is moved by the electromagnet from a blocking position where the latch blocks the firing pin to move in a firing direction to a non-blocking position where the latch does not block the firing pin when the electromagnet is in an excited state. The controller, during an excitement period, controls the driving circuit to provide constant current for a first time period to excite the electromagnet to the excited state, and provide pulsating current for a second time period to keep the electromagnet in the excited state.

摘要： The invention relates to a handheld nail setting device comprising highly dynamic electromagnetic drive in the manner of a Thomson coil with soft-magnetic frame, comprising a first excitation coil (30) whose winding height is greater than its length, which hence is flat; a soft-magnetic frame in which the first excitation coil is arranged and against which it abuts, and which in in the manner of a pot magnet constitutes an open magnetic circuit which includes an outer region, a bottom and an inner region, and which is open on its end face, wherein the first excitation coil at least partly encloses the inner part of the frame; a short circuit armature preferably formed hollow cylindrical at least on its side facing the first excitation coil, which is movably mounted along an axis and which in its stroke starting position dips into the end-face opening of the frame and thereby at least partly encloses the inner part of the frame, wherein the frame entirely or predominantly is formed of a soft-magnetic composite material or one or more sheet stacks, which has a saturation flux density of at least 1.5 T and an effective specific electrical conductivity of not more than 106 S/m, and the first excitation coil and/or the frame include at least one means for strain relief, in particular in the form of an enclosure in order to at least partly absorb at least the radial forces occurring on the first excitation coil during an actuating operation vertically to the direction of movement, and wherein the Lorentz force acting on the short circuit armature is used to perform work.

摘要： 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.

摘要： A striking device includes a swing arm unit, an impact member and two restoring units. Each of the restoring units includes a stationary seat removably connected to the swing arm unit, a moving seat removably and co-movably connected to the impact member, first and second coupling sets, and a resilient member interconnecting the stationary seat and the moving seat to bias the moving seat toward the stationary seat. For each of the restoring units, two portions of the first coupling set are formed respectively on the stationary seat and the swing arm unit and coupled removably with each other, and two portions of the second coupling set are formed respectively on the moving seat and the impact member and coupled removably with each other.
