POWER TOOL

摘要

A power tool (1) includes an electric motor (2) as a drive source and a start switch (20; 61) that starts the electric motor (2) and is lockable in an ON position in a lock-ON state. An electromagnetic actuator (30; 40; 50; 60) pushes out or pulls in an actuation pin (30a; 40a; 50a; 60a) with respect to a body of the electromagnetic actuator (30; 40; 50; 60) in response to cutting off of a supply of electrical current to the power tool (1). The pushed-out or pulled-in actuation pin, directly or indirectly, disengages the start switch (20; 61) from the lock-ON state and/or prevents the start switch (20; 61) from being shifted into the lock-ON state.

1. A power tool comprising:
an electric motor as a drive source, a start switch configured to start the electric motor, the start switch being movable between an OFF position and an ON position and being engageable or latchable in a lock-ON state, and an electromagnetic actuator configured to advance an actuation pin out of a body of the electromagnetic actuator in response to interruption of a supply of electric current to the power tool, wherein: the start switch and the actuation pin are arranged such that, when the supply of electric current to the power tool is interrupted and the actuation pin is advanced, the advanced actuation pin, directly or indirectly, (i) causes the start switch to be disengaged or latched from the lock-ON state and/or (ii) prevents the start switch from being engaged or latched in the lock-ON state.
