<p>PURPOSE: To eliminate the need of work for turning an engaging/disengaging mechanism around a T-type connecting rod by providing a hooking mechanism with the T-type connecting rod on the clamp body side, and a resilient member for urging the hook on the open end side of a clamp cover inwardly. CONSTITUTION: A hook mechanism comprising a T-type connecting rod 8, a hook 11 fixed to the open end side of a clamp cover 7, and a leaf spring 12 for urging the hook 11 inwardly is disposed between a clamp body 6 and the clamp cover 7. The hook 11 can be engaged with the T-type head part 8a of T-type connecting rod 8 when the clamp cover 7 is closed such that it can be disengaged therefrom. This structure eliminates the work for turning an engaging/disengaging mechanism around the T-type connecting rod 8 thus enhancing the workability.</p> |
