Battery operated tool e.g. electric drill, has angle limiting zone including two stop blocks whose ends contact each other such that body of battery case does not rotate at three hundred and sixty degrees

摘要

The tool has a battery case including a body and an articulated tube that extends from an upper end of the case. The tube is inserted into a hollow portion of a grip and is rotated between two positions. An angle limiting zone (50) has a stop block that is introduced into the case and another stop block that extends from the grip. The ends of the blocks contact each other such that the body does not rotate at 360 degrees.
