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 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.

An actuation system for preventing actuation of a base device upon a non-target substrate. The actuation system includes a detector configured to generate and transmit a profile signal of a test substrate. A processing unit is in communication with the detector and configured to receive the profile signal of the test substrate from the detector, the processing unit being configured to determine whether the profile signal of the test substrate corresponds to a profile signal of a target substrate, and to generate an actuation signal if the profile signal of the test substrate corresponds to the profile signal of the target substrate. An actuation unit is in communication with the processing unit and the base device, the actuation unit being configured to receive the actuation signal from the processing unit and to permit the base device to actuate when receiving the actuation signal.

The present disclosure provides various embodiments of a fastener-driving tool that includes a battery-charged supercapacitor as a power source. The fastener-driving tool includes first and second spaced-apart, conductive rails and a partially conductive piston slidably mounted on the rails. The rails and the piston are electrically connected to one another. The supercapacitor is electrically connected to the first rail. When the supercapacitor discharges electrical current, the electrical current flows from the supercapacitor, into the first rail, through the piston into the second rail, and from the second rail. The electrical current induces magnetic fields in the rails and the piston, and the combination of the electrical current and the magnetic fields induce a Lorentz force that acts on the piston to move the piston toward a nosepiece to drive a fastener.

A fluid damper includes a cylinder tube portion which is filled with a fluid, a piston which is provided so as to be movable in an inner portion of the cylinder tube portion and whose moving speed is controlled with resistance of the fluid, and a biasing member which expands and contracts in accordance with a position of the piston and which applies a force corresponding to an expansion and contraction amount of the biasing member to the piston. The resistance of the fluid at a time the piston moves is changed in accordance with the position of the piston.

An air-path structure of a pneumatic nail gun includes a main chamber formed in a gun body, a piston driving chamber and a timekeeping chamber that continuously releases pressurized air to the outside. The gun body is equipped with a trigger valve and a bar valve, and a security chamber and an auxiliary chamber are formed in the trigger valve; the trigger valve controls the pressurized air in the piston driving chamber to be discharged to the outside; and the bar valve controls the pressurized air in the main chamber to go into the piston driving chamber, the timekeeping chamber and the auxiliary chamber. The security chamber is permanently connected to the main chamber for concentrating upon the pressurized air, and the bar valve controls the pressurized air in the main chamber to be discharged into the timekeeping chamber, so as to improve the safety of pneumatic nail gun when used.

A driving tool capable of suppressing the increase in the number of components is provided. The driving tool includes an ejection unit 23 to which a fastener is supplied and a striking unit capable of moving with respect to the ejection unit 23 so as to drive the fastener supplied to the ejection unit 23 into a workpiece, and the driving tool further includes a first push lever 74 capable of contacting with and separating from the workpiece and capable of moving with respect to the ejection unit 23, a second push lever 135 capable of moving in conjunction with the first push lever 74, and a blade guide 120 and a cover 30 having a function to guide a movement of the first push lever 74 and the second push lever 135 with respect to the ejection unit 23 in a predetermined direction.

A cordless, hoseless fastener driver tool with a compressed gas pressure chamber has a removable end cap that is securely attached to the tool via four screws. Removing each screw in succession releases the compressed gas in a controlled manner, which then allows a user to safely remove the end cap to access the interior of the tool. The user can perform a maintenance procedure and service the interior mechanical portions of the tool, such as repairing or replacing a driver, a piston, and/or a piston stop, as well as the cylinder sleeve, or other internal components. Once the end cap is removed, the components listed above can be removed (and replaced) without the use of any further tools.

This relates to a driving tool for driving fastening means, nails/staples, into a workpiece, a trigger lever, which can be actuated manually, and a workpiece contact element, which can be actuated by placing the tool onto the workpiece, the tool operates in a single shot mode, in which each individual sequence of an actuation of the workpiece contact element with subsequent actuation of the trigger lever triggers a driving-in cycle, the tool operates in a bump firing mode, in which, with the trigger lever continuously actuated, each individual actuation of the workpiece contact element triggers a driving-in cycle, a resetting assembly providing, by means of which the tool is resettable from the bump firing mode into single shot mode in an automatic, time-controlled resetting operation. It is proposed that a signaling assembly, which emits a feedback signal to the user before, after or during each automatic resetting operation, is provided.
