A fastener driving tool that forces air from its variable venting volume beneath the piston of the working cylinder and directs that forced air through passageways and toward an electronic controller and/or an electric motor before being vented to atmosphere, thereby drawing heat away from those components during an operational cycle of the movable piston. When the piston returns to its initial position, environmental air is drawn through the same passageways, again past the electronic controller and/or electric motor, thereby twice cooling these “hot” components during a single operational cycle.

A nailing unit comprising a nail box, a nail magazine, a nail pushing block, a tail buckle switch, a nail limiting block fit together with a nail guiding plate through slits is provided. The nail magazine includes a heat-treated guide rail assembly mounted with a nail splitting plate at the end near the nail guiding plate; the nail pushing block which is connected to a spring is formed with three nail pushing feet adapted to a first, second, and third gaps; the nail guiding plate includes two connecting wings and forms a low-lying guide plate therebetween; each angle between the guide plate and each connecting wing is respectively fixedly provided with a positioning step along the longitudinal direction.

The nailing unit fulfills efficient nailing for T nails, straight nails, and different types of code nails and U nails, and prolongs the service life of the nail gun.

An electric stapler includes a main body, a handle, a striking assembly, and a safety mechanism between the main body and the handle. The handle is movable with respect to the main body between an original position and an unlock position. The striking assembly includes a striking mechanism for striking the staple out and a trigger switch on the handle for triggering the striking mechanism. The trigger switch has a strikable state and a locking state. When the handle is at the original position, the safety mechanism is at a locking mode to make the trigger switch at the locking state. When the handle is at the unlock position, the safety mechanism is at an unlock mode to make the trigger switch at the strikable state. An angle between the moving direction of the handle and the striking direction is smaller than 90 degrees.

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.

An electric stapler includes a clamp part that is configured to include a first wall portion and a second wall portion for gripping a paper bundle, a penetration part that causes a staple to penetrate the paper bundle gripped by the clamp part, a clinch part that bends the staple penetrating the paper bundle to bind the paper bundle, a gripping release detection unit that detects that the paper bundle is released from gripping after the first wall portion moves in the direction of separating from the second wall portion from a state where the paper bundle is gripped by the clamp part; and an output unit that, after it is detected that the paper bundle is released from gripping of the clamp part, outputs a gripping release signal indicating that the paper bundle is released from gripping of the clamp part to an outside.

An electric stapler includes a clamp part, a penetration part, a clinch part, and a motor, the penetration part, and the clinch part. The electric stapler performs binding processing accompanying rotation of the motor by sequentially performing a clamping process, a penetrating process, and a clinching process. The electric stapler includes a first position detection unit that detects that a rotational position of the motor passes a first position, a braking unit that applies braking to the motor after it is detected that the motor passes the first position, a difference calculation unit that calculates a difference between a position at which the motor is stopped by the braking unit and a predetermined stop target position of the motor; and a motor control unit that moves a rotational position of the motor to the stop target position by rotating the motor forward or in reverse by the calculated difference.

An electric stapler includes a clamp part that clamps a paper bundle, a penetration part that causes a staple to penetrate the paper bundle, a clinch part that bends the staple penetrating the paper bundle to bind the paper bundle, a driving unit that drives the clamp part, the penetration part, and the clinch part. The electric stapler performs binding processing by at least performing a clamping process of clamping the paper bundle with the clamp part, a penetrating process of causing the staple to penetrate the paper bundle with the penetration part, and a clinching process of bending the staple penetrating the paper bundle with the clinch part. The electric stapler includes a state detection unit that detects a state of the driving unit in each of the clamping process, the penetrating process and the clinching process, and a storage unit that stores the detected state.

The disclosure discloses a stuck staple processing mechanism of an electric stapler and the electric stapler. The stuck staple processing mechanism of the electric stapler includes a driving mechanism, a transmission mechanism, a pop-up staple channel assembly, a controller and a pop-up mechanism. The transmission mechanism is connected with a pop-up switch of the pop-up staple channel assembly through the pop-up mechanism. When the controller controls the driving mechanism to rotate along a staple placing direction, the pop-up mechanism does not make the staple channel assembly act. When the controller controls the driving mechanism to rotate in an opposite direction of staple placing, the transmission mechanism makes the pop-up switch act through the pop-up mechanism to pop up a staple channel of the staple channel assembly, so as to facilitate a removal of a stuck staple.
