Patent ID: 8555999

Claim:
A power tool comprising: a first housing portion; a battery mounted to the first housing portion; a second housing portion that is rotatable relative to the first housing portion between a first position, in which the first and second housings are arranged in an in-line arrangement, and a second position in which the first and second housings are arranged in a pistol-grip arrangement; a powertrain received in the second housing portion and having an output member, the output member extending from the second housing portion and being movable about an output member axis, the powertrain comprising an electric motor and a transmission; a trigger coupled to the first housing portion and electrically coupled to the battery and the electric motor, the trigger being configured to control operation of the electric motor; a mounting hub fixedly coupled to one of the first and second housing portions; and a lock bar slidably mounted to the other one of the first and second housing portions for movement in a direction that is transverse to a longitudinal axis of the other one of the first and second housing portions between a locked position and a first unlocked position, the lock bar cooperating with the mounting hub in the locked position to inhibit relative rotation between the first and second housing portions, and wherein placement of the lock bar in the first unlocked position permits relative rotation between the first and second housing portions; wherein when the second housing portion is positioned in at least one of the first and second positions, the longitudinal axis of the other one of the first and second housing portions is coincident with the output member axis.
