An electric nail gun includes a cylinder unit, a valve, an actuating member, a safety assembly and an adjusting assembly. The cylinder unit defines a cylinder space and a gas space. The valve is disposed between the cylinder space and the gas space, and is movable among a closed position, in which the valve closes the cylinder space, and a plurality of open positions. The safety assembly has a pressing portion that is adapted to be pressed and moved by an object, and an actuating portion that cooperates with the actuating member to define a first actuating distance in a first direction therebetween. When the pressing portion is moved by the object, the actuating member is urged to move by the actuating portion such that the valve moves from the closed position to one of the open positions. The adjusting assembly is operable to adjust the first actuating distance.

A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, and a driver blade attached to the piston and moveable therewith from a retracted position to a driven position to drive a fastener into a workpiece. A fill valve is coupled to the cylinder and operable to selectively fill the cylinder with gas to a pressure.

The invention relates to a drive-in device, comprising a drive-in piston which is guided in a cylinder for driving a nail element into a workpiece and comprising a combustion chamber which is arranged over the drive-in piston and which can be filled with a combustion gas, said combustion chamber comprising a cylindrical portion which is symmetrical about a central axis (A). A movable combustion chamber wall of the combustion chamber can be adjusted along the central axis (A), and a spring is supported between the movable combustion chamber wall and a housing. A force vector (F) of the spring has a lateral offset (V) with respect to the central axis (A).

A nail-driving gun trigger assembly includes a hand-grip, a trigger piece, a safety latch and a release button. The safety latch is mounted on the trigger piece and is movable relative to the trigger piece. The release button is mounted on the trigger piece and is movable relative to the trigger piece. The release button and the safety latch are co-movable with the trigger piece relative to the hand-grip. The trigger piece is stopped from moving by engagement between the safety latch and the hand-grip. The release button is in sliding contact with the safety latch for disengaging the safety latch from the hand-grip and for permitting movement of the trigger piece relative to the hand-grip.

The invention relates to a drive-in device, comprising a drive-in piston, guided in a cylinder, for driving a nail member into a workpiece, and a combustion chamber arranged above the drive-in piston, said combustion chamber being Tillable with a combustion gas, wherein the combustion chamber has a bottom that is adjustable along an axis, wherein the bottom has a groove that extends in the circumferential direction and has an inserted seal which bears in a radial direction against a rigid combustion-chamber wall, wherein a front surface, in the axial direction, of the seal protrudes in the direction of the axis from a terminating plane of the groove.

The invention relates to a nail device for setting nails into an object, comprising a housing, a setting mechanism for setting the nail along a setting axis, a bolt-guiding element for contacting on the object at a first contact point, in particular a trigger for activating the setting mechanism, a swivelable support foot for contacting on the object at a second contact point, wherein a connecting line between the first and the second contact point and the setting axis span a device plane of the nail device, characterised in that the swivel axis of the support foot is oriented substantially perpendicular to the device plane.

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.

The screwing accessory device comprises a receiving box, a rack and a pushing component. The receiving box is for receiving the screwed component. The rack is connected to the receiving box. The pushing component is disposed within the receiving box and is used for pushing the screwed component.

A drive-in tool for driving fasteners into a workpiece, wherein the tool comprises in particular: a safety device (8) which is coupled with the trigger element (6) and is set up to bring about a transfer of the drive-in tool (1) from a trip-ready state (100) into a secured state (101) after expiry (820) of a delay time which proceeds from an activation (810) of the safety device (8), wherein the safety device (8) comprises a control volume (15), wherein the safety device (8) comprises an activation element (33) which is changeable between a first and a second position by way of the trigger element (6), wherein in the first position of the activation element (33) a first pneumatic connection is defined between the control volume (15) and the gas pressure source connection (23), which is hereafter referred to as charging connection (27.1), and wherein in the second position of the activation element (33) a second pneumatic connection is defined between the control volume (15) and a pressure sink (40), which is hereafter referred to as discharging connection (33.1), wherein one connection from the charging connection (27.1) and the discharging connection (33.1) comprises a smallest cross-sectional flow area which, together with a gas pressure of the gas pressure source, determines the delay time of the safety device (8). The present disclosure also relates to a corresponding method for operating a drive-in tool.

A drive blade lubrication assembly for use in a powered fastener driver (10). The powered fastener driver (10) contains a drive blade (42) which snap-fits with a reciprocating piston (58) by a blade seal (103) assembly. The drive blade lubrication assembly contains a lubricant applying member adapted to apply lubricant to a portion of the drive blade (42); and a lubricant storing device which is in fluid communication with the lubricant applying member. The lubricating storing device is adapted to replenish the lubricant in the lubricant applying member. A powered fastener driver (10) containing a drive blade lubrication assembly is also described. The use of the lubricant storing device in the present invention ensures that lubricant is continuously supplied to the drive blade (42) after long time usage of the powered fastener driver (10), so that friction between the drive blade and the blade seal assembly is minimized
