An electric nail gun includes a supporting frame, a swing arm, a driving unit, and a safety unit. The swing arm has a driven segment and is pivotable relative to the supporting frame between a standby position and a shooting position. The driving unit includes a driving member in contact with the driven segment of the swing arm and operable for moving the swing arm towards the shooting position. The safety unit has a stopping member that is driven by the driving member to move relative to the driven segment between a stopping position, where the stopping member blocks movement of the driven segment, and a releasing position, where the movement of the swing arm towards the shooting position is permitted.

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 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.

A nail gun includes a frame unit, a flywheel, and a nail-striking device that includes an actuation unit, an impact member and an accidental discharge prevention unit. The actuation unit includes a safety subunit. The impact member has a confining portion. The accidental discharge prevention unit includes a restraining member located between the confining portion of the impact member and the safety subunit. The actuation unit is operable to convert the restraining member from a restraining state, in which the restraining member restrains movement of the confining portion of the impact member, to a releasing state, in which the movement of the confining portion of the impact member is permitted.

A driving tool comprises a displacement allowing mechanism that allows a wheel to be displaced in a radial direction of a rotation shaft. The driving tool further comprises a displacement restricting mechanism that restricts the wheel from being displaced in the radial direction of the rotation shaft. When a driver is to start being moved upwards by an engagement of a first engagement portion with an engaged portion by rotation of the wheel, a displacement restriction state of the wheel caused by the displacement restricting mechanism is released, allowing an entirety of the wheel to be displaceable in the radial direction of the rotation shaft due to the displacement allowing mechanism.

A fastener driving tool with a working cylinder and a piston, the piston outer surface having a lubricant-saturated foam material that stores and dispenses lubricant into the piston-cylinder wall interface, thereby increasing the performance and lifespan of the tool. Another embodiment discloses a two-part piston in which the bottom portion is made of metal and absorbs the main mechanical loading forces of the piston drive and return strokes, and the top portion is made of a non-metallic material that has surfaces that act as sliding bearings against the inner wall of the cylinder.

A driver including: an ejection part to which a fastener is supplied; a driver blade which moves from a first position toward a second position and drives the fastener into a driven member; and a rack provided to the driver blade. The driver further includes: a rotary component engaging with the rack and moving the driver blade from the second position to the first position; and a lock plate engaging with the rack. The driver blade moves from the second position to the first position while the rotary component rotates once, the rotary component is released from engaging with the rack after the driver blade moves from the second position to the first position, and moves from the first position to the second position, and the lock plate is engageable with the rack when the driver blade stops before reaching the second position from the first position.
