OSCILLATING POWER TOOL

WIPO Patent Application WO/2016/082768

A1

An oscillating power tool (1), comprising: a switch starting up and shutting down a motor (23); a trigger piece (25) used for triggering the switch; a transmission mechanism; an adjustment mechanism (6) used for enabling the oscillating power tool (1) to have different oscillation angles. The oscillating power tool (1) also comprises a stopper mechanism movably arranged with respect to a housing (2), the stopper mechanism having two positions. When the switch starts up the motor (23), the stopper mechanism is located in a first position, and prevents the adjustment mechanism (6) from adjusting the transmission mechanism. When the adjustment mechanism (6) adjusts the transmission mechanism, the stopper mechanism is located in a second position, and prevents the switch from starting up the motor (23). A user is not able to adjust the oscillation angle when the oscillating power tool (1) is turned on. During adjustment of the oscillation angle by the adjustment mechanism (6), i.e. when the adjustment mechanism (6) is not adjusted in place, the user is not able to turn on the oscillating power tool (1). The present technical solution increases the reliability of the oscillating power tool (1), and improves operational safety.
