A driving tool includes: a body provided with an outlet where a fastener is driven; an urging member attached to the body; and a plunger movable in a projecting direction toward the outlet by extension of the urging member. An urging force in the projecting direction acts on the body from the urging member when the urging member is extended.

A driving tool includes: a plunger movable in a first direction along a direction in which a fastener is launched; an urging member that is extendable and contractible in the first direction and serves as a drive source of the plunger; and guide rails configured to guide movement of the plunger in the first direction. The guide rails extend along the first direction of the urging member and are disposed on both sides sandwiching the urging member, and the guide rails are arranged such that a virtual line connecting the guide rails on the both sides of the urging member is deviated from a central axis of the urging member in a plan view of the urging member as viewed from the first direction.

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.

A fastener driving tool that includes a lift mechanism for moving the driver from a driven position to a ready position. In one embodiment, the lift mechanism is mounted to a movable pivot arm, and the pivot arm is slightly rotated to allow the driver to drive a fastener; when the driver is to be lifted in a return stroke, the lifter subassembly is moved back into engagement with the driver, and multiple lifter pins contact protrusions in the driver to lift the driver from the driven position to the ready position. In another embodiment, the pivotable lifter floats along the driver, and “releases” from contact only to prevent a jam or otherwise undesirable operating condition involving the driver; otherwise, the lifter remains nested in the tool's guide body during all operating states. A solenoid-operated latch also is provided to prevent the driver from moving downward (for driving a fastener).

A driver capable of suppressing increase in a load torque of a motor when a striking mechanism is moved by the torque of the motor against a force of a first moving mechanism is provided. The driver includes a striking mechanism 12 movable in a first direction B1 and a second direction B2 opposite to the first direction B1 and a first moving mechanism configured to move the striking mechanism 12 in the first direction B1 to strike a fastener, and the driver further includes a motor, a second moving mechanism 45 rotated by the torque of the motor and configured to move the striking mechanism 12 in the second direction against a force of the first moving mechanism, and torque suppression mechanisms 45A to 45H configured to suppress increase in the torque of the motor when the striking mechanism 12 is moved in the second direction B2.
