发明名称 Chain tightener attachment
摘要 An attachment slidably engageable with the handle of a chain tightener for supplementing handle leverage. An end fitting on the attachment has an opening along one side through which the handle end may move during release of the tightener to permit separation in a harmless manner. A stop limits the extent of handle insertion into the fitting to contribute toward desired separation.
