发明名称 ADJUSTABLE BENT HOUSING WITH ROTATIONAL STOP
摘要 An adjustable bent housing includes an outer tubular member having an interior surface defining an interior bore. The outer tubular member has a first angular offset. An inner tubular member is provided and has an exterior surface. The inner tubular member has a second angular offset. The inner tubular member has at least one engagement end received within the interior bore of the outer tubular member. A desired cumulative angular offset is selected by relative rotation of the outer tubular member and the inner tubular member to adjust the positioning of the first angular offset relative to the second angular offset. A rotational stop is provided that limits relative rotation of the outer tubular member and the inner tubular member to a limited rotational range. A locking sleeve locks the outer tubular member and the inner tubular member in a selected rotational position to fix the cumulative angular offset.
