These two clamping locations lock and unlock their respective pivot balls independent of locking of the other pivot ball. Furthermore, the locking mechanisms utilized to lock the pivot balls also utilize the lock the angular position of the extension rod relative to the clamp. An adjuster intermediate the clamping positions allows for the movement of the clamping location relative to each other.
