Abstract: A Smooth Disengagement with Quick Clamping Mechanism designed for increasing efficiency and improving the quality of clamping systems that can be used in various vises, C-clamps and all other clamping applications. This invention applies a concept of using two sets of opposing thread angles; one thread set is used at engagement, while the other is used at clamping.
