An electric carpet stapler comprises a trigger and switch assembly that has an actuation caused by a change of state of a sensor, which causes the sensor to send a signal to a control circuit to begin a process to supply power to a winding. The trigger and switch assembly includes a trigger that moves in a trigger actuation direction to move a sensor actuator in a sensor actuation direction, causing a change of state in the sensor, which causes the control circuit to begin the process to supply power to the winding. The trigger and switch assembly may also include a toggle. At the actuation of the trigger and switch assembly, the toggle creates a mechanical instability, and a toggle signal to the user, which may be produced mechanically.

A nail gun includes a gun body, a muzzle unit, a nail-feeding unit, a nail-striking unit, and a control unit for controlling the nail-feeding unit and the nail-striking unit to implement a method for feeding nails. The method includes the following steps: energizing a nail-striking solenoid valve of the nail-striking unit to perform a nail-striking operation on one of the nails; de-energizing the nail-striking solenoid valve, and simultaneously starting to count a predetermined delay time period in idle; and upon elapse of the predetermined delay time period, energizing a nail-feeding solenoid valve of the nail-feeding unit to perform a nail-feeding operation on another one of the nails.

A power tool including a housing and a motor housed in the housing. There is a spring engine housed in the housing and a driver blade driven by the spring engine. Additionally, the power tool holds a pipe clamp configured to be driven into a workpiece by the driver blade.

A tool is provided for applying fasteners to a workpiece. The tool as a magazine that carries multiple fasteners and is carried by a housing. A driver blade is provided to drive a lead fastener into a workpiece. The driver blade has a driving edge with a profile that includes driving projections, having curved contact surface for contact with curved edges of the fastener, and a relief portion therebetween that is recessed relative to both projections and contact surfaces. Further, the tool includes a lockout assembly for limiting movement of the driver blade and contact trip, thereby limiting activation of the motor. The pusher may include a pusher lockout surface that is designed for movement in an opposite direction to a feed direction by the contact trip as well as configured to slide over a locking art of the contact trip when the fasteners are empty or nearly empty.

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 staple gun and a method of using the same. A stapling mechanism in the housing is activated to deliver a staple through an aperture in a housing wall and drive the staple into a surface around a stack of one or more electric cables. The gun includes a reciprocating cable guide for centering the gun on the stack of cables and closing a safety switch to permit the gun's trigger to be activated. A spacer extending outwardly from the housing wall rests on the upper surface of the cable stack. The spacer and a bumper that engages a hammer of the stapling mechanism provide for automatic depth adjustment when driving the staple into the surface. A reciprocating cable guard extending outwardly from the housing wall is positioned between the stack of cables and the staple to aid in preventing the staple from piercing the cable.
