摘要： A main mount (52) having a central hub (58) is secured to a turnbuckle. A ring gear (66) surrounds the hub. A motionless bearing (70) fits over the hub and is held in place with a locking ring (82). The motionless bearing (70) includes several bores that receive a driving bit (90) that engages the ring gear. As the driving bit is rotated, the main mount is rotated about the motionless bearing thereby tightening or loosening the turnbuckle.
