A fastener driver includes a housing defining a head portion and a handle portion, a drive mechanism positioned within the housing, and a firing mechanism. The firing mechanism includes a primary guide member supported within the head portion of the housing, a secondary guide member spaced from the primary guide member and supported within the head portion of the housing, a piston slidable along the primary guide member and the secondary guide member, a driver blade attached to the piston and configured to be movable along a drive axis, and a biasing member configured to move the piston and the driver blade from a top dead center (TDC) position toward a bottom dead center (BDC) position. A lifter assembly is operated by the drive mechanism to return the piston and the driver blade towards the TDC position, against the bias of the biasing member.

A magazine for use with a fastening tool. The magazine can have a pusher assembly that can be retracted into a recess in the magazine to facilitate loading and reloading of fasteners. The pusher assembly can have a pusher assembly knob which can be reversibly latched to a detent to maintain the pusher assembly in a retracted state. The fastening tool can use a magazine which can be reloaded by a method which has a step of reversibly retracting the pusher assembly into the retracted state to allow for feeding one or more fasteners to the magazine.

An apparatus for driving a fastening element in a driving direction into a base material, having a receptacle for the fastening element, from which the fastening element is driven into the base material, having a magazine for supplying fastening elements in a transport direction to the receptacle, wherein the side of the magazine facing the driving direction has a slot which runs in the transport direction, and having a dust deflector which covers the slot.

A fastening tool including a magazine securely and releasably retained on the fastening tool by a cam mounted on one of the fastening tool and the magazine. In a single rotary motion, the cam wedges together the housing member of the fastening tool and the housing member of the magazine, while simultaneously rotating cam lobes into respective chambers formed on the fastening tool and the magazine. The cam rotation and magazine retention system is accomplished without tools.

A nail supply device for pneumatic nail gun, including a piston seat, a longitudinal slideway, a transverse slideway connected to the longitudinal slideway, nail guide plates, and a slide clearance; the lower surface of the piston seat having a nail output interface; the upper surface of the piston seat having a nail inlet hole vertically connected to the nail output interface, the front side of nail inlet hole is connected to the rear side of longitudinal slideway; the front sidewall of the piston seat having a piston hole and a nail push hole adjacent to the piston hole, the nail push hole is connected to the longitudinal slideway. The nail supply device for pneumatic nail gun of the present invention can supply nails automatically when the pneumatic nail gun is nailing, the nailing efficiency and nailing quality are guaranteed effectively.

A magazine for use with a fastening tool. The magazine can have a pusher assembly that can be retracted into a recess in the magazine to facilitate loading and reloading of fasteners. The pusher assembly can have a pusher assembly knob which can be reversibly latched to a detent to maintain the pusher assembly in a retracted state. The fastening tool can use a magazine which can be reloaded by a method which has a step of reversibly retracting the pusher assembly into the retracted state to allow for feeding one or more fasteners to the magazine.

An active safety device and method for fastener tools that includes a first sensor that detects a hazardous target; a first driver that drives the fastener a minimal distance into the material, the fastener being conductive and acting as a second sensor; a second driver that drives the fastener into the material; a processor that receives information from the first sensor and determines if a hazardous target is detected by said first sensor and engages a trigger interlock if the hazardous target is not detected the first driver is engaged and said second sensor provides information on the composition of the material to the processor; wherein the processor engages the trigger interlock when it determines if the composition of the material is classified as a hazardous target and otherwise initiates the second driver to drive the fastener into the material.

A control and protection mechanism and a nail gun having the same. The control and protection mechanism includes first and second micro-motion switches, a toggle block, a lock pin, an actuating member, a micro-motion contact and a driving rod. The switch bracket is attached to the main body; the first and second micro-motion switches are fixed on the switch bracket; the toggle block is rotatably attached to the switch bracket, and includes a lock groove, a trigger end and a toggle end. The toggle end is operably coupled to the first micro-motion switch and the trigger end extends into inside the main body such that when the piston moves in the cylinder to a position, the piston pushes the trigger end to prompt the toggle block to rotate and therefore the toggle end to move, thereby causing the first micro-motion switch to change its switch state.

An energy storage mechanism and a nail gun having the same. The nail gun includes a driving mechanism having a piston, a nail striking member co-movably connected to the piston, and a driving member being operably alternatively engaged and disengaged with the nail striking member. The energy storage mechanism includes a cylinder and at least one spring disposed in the cylinder such that an engagement of the driving member with the nail striking member causes the piston to move backward in the cylinder to push the at least one spring into a contract state so as to store energy therein, and an disengagement of the driving member with the nail striking member causes the least one spring to release the stored energy therein to push the piston to move frontward in the cylinder so that the nail striking member is co-moved therewith to strike a nail out of a muzzle.

In order to make it possible to easily carry out filling up of a compressed air to a compression chamber without making a fastener driving machine larger in size, there is provided a fastener driving machine that includes a cylinder that forms a piston chamber defined by a piston and drives a driver blade by the piston. The housing has a cylinder case part for housing a cylinder, and a handle part. A pressure accumulating container is provided on the cylinder. The pressure accumulating container includes a bottom wall portion and a top wall portion. A compression chamber that communicates with the piston chamber is provided therein.
