An angle grinder is provided to be operated continuously by keeping a trigger paddle pressed by a locking member. An angle grinder comprises a trigger assembly equipped with a motor in a housing. The trigger assembly comprises a switch(24), a trigger, and a locking member(60). The switch is installed in the housing to turn on and off the motor. The trigger is extended from the housing so that a user can hold it, has a first arm(52) and a second arm(54), and pivots between a first position and a second position. The locking member is engaged with the second arm of the trigger. When the trigger is positioned in the second position, the second arm contacts with the switch to drive the motor and the second arm can be engaged with the locking member. When the trigger is positioned in the first position the second arm moves away from the switch so that the second arm cannot be engaged with the locking member.
