(57) Abstract Objective Without causing the difference in level on the body receiving aspect of C hookBe able to expand and contract the Tip side of the hook body, the whole structure with the compactExpansion and contraction operation smooth expansion and contraction C hook and double type expansion and contractionC hook is offered. Constitution This expansion and contraction C hook horizontality of C forma hook component shiftParalleling to the longitudinal direction in the surface of the fixed switch hook, it is formed by one body,It is outside the sudden provision section and the fixed switch hook sleeve possibly to be installed,It is the slide hook component and this slide hook component shiftTo possess with the Drive device which is made to move alongside the fixed switch hook, C formaAs for sudden provision section of fixed switch hook of hook component this suraidohutsuWay with the shoulder of the ku component it touches to the inner circumference section of the suffering body,It has exposed from the slide hook component. Double of this deviceAs for type expansion and contraction C hook the above-mentioned expansion and contraction C hook pair suspender itself hu You stick in remu, the bottom contacts with the hook breech operating mechanism,It has reached the point where it opens.
