The clamping assembly (120) has an outer member (130), an inner member (132), and wedges (134) that are guided by keyways (162) on the inner member (132). A user pushes onto the inner member (132), which causes the wedges (134) to contact a cam surface (144) on the outer member (130), which forces the wedges (134) in a radial inward direction until threads (164) provided on said wedges (134) clamp onto complimentary shaped threads (128a) on a draw stud (128).</p> |
