Abstract
In an angle-grinder with a rotating handle and a latch for fixing the handle in two different rotational positions, an interlock mechanism is provided for greater security against unwanted rotation of the handle when the tool is being used. The interlock mechanism is moved to a locking position by depressing the trigger to start the motor, and thus provides a safety lock backing up the latch, in case the latch is accidentally released during use. In its unlocking position the interlock mechanism may prevent actuation of the trigger when the handle is not properly aligned in one of its operating positions.
