Abstract
A working tool includes a housing (10) and a lever (3) having a gap defined therein for accommodating a rotatable switch lock (1). The switch lock has a first engagement portion (1a) defined on a first side and a stopper portion (1b) defined on a second side, and the lever has a support portion (3a) proximal to the first engagement portion. A handle portion of the housing has a left push button (8) and a right push button (5) inserted therein, a first groove (8a) and a second groove (8b) of the left push button (8) and right push button (5) each having a second engagement portion formed on a groove wall thereof, each of a first extension section (3a-2) and second extension sections (3a-1) being provided with, at a side facing a corresponding second engagement portion, a third engagement portion engageable with the corresponding second engagement portion. The working tool is capable of reducing operation mistakes as much as possible, preventing inadvertent shutdown of the motor, and allowing any operator, no matter left-handed or right-handed, to operate it conveniently.
