Abstract

It is an object of the invention to provide an improvement of the operability in a driving operation using a power tool. A representative power tool may comprise a driving material driven into a workpiece, a driving mechanism to drive the driving material into the workpiece, a motor, an operating device that controls energization and de-energization of the motor including a trigger switch and an internal switch, wherein the operating device further comprising a first mode in which, when the trigger switch is depressed, the internal switch is interlocked with the depressing operation of the trigger switch to be turned to the on-position and held in the on-position, while the trigger switch is returned to the off-position when the trigger switch is released and a second mode in which, when the depressing operation of the trigger switch is continued, the trigger switch is held in the on-position, and the internal switch is released from interlock with the trigger switch and is held in the on-position for a predetermined period of time in the working stroke and then returned to the off-position, while the trigger switch is returned to the off-position when the trigger switch is released.

Description

technical field [0001] The present invention relates to a driving tool for performing a driving operation of a driver by causing a driving member to move linearly. Background technique [0002] In JP Utility Model Registration No. 2567867 (Patent Document 1), a starting mechanism (operating device) of a nailing machine is disclosed: as the driving force of the driving operation of the driver of the driving member, a coil spring is used to drive the driving force. elastic force. The starting mechanism described in Patent Document 1 includes: a contact detection arm that comes into contact with a workpiece when driving a nail; a trigger that is pulled by a user's finger; and a lever composed of a plurality of levers. A mechanism, which is operated by the above-mentioned contact detection arm, or operated by a trigger, to connect or disconnect each other; a power switch, which switches the ON / OFF state through the lever mechanism. When the trigger is pulled while the contact ...
