ABSTRACT:
A hedge trimmer is provided which performs a trimming operation on a hedge. The hedge trimmer includes a machine body, a handle rotatably attached to the machine body, a throttle lever provided in the handle, a locking mechanism for preventing the handle from rotating relative to the machine body, and an unlocking member for unlocking the locking mechanism from the machine body. The unlocking of the locking mechanism from the machine body is effected by a slide movement of the unlocking member towards a rear part of the handle. When unlocking the locking mechanism from the machine body, the unlocking member surrounds the throttle lever so that the throttle lever can be inoperable with the result that the throttle lever is prevented from being erroneously operated during the rotational operation of the handle.
