Chain hanging hook for suspending object, has buckle with penetration groove that traverses two interior sides and exterior side of buckle, and moving axle positioned by pin and including notch

摘要

The hook (1) has a buckle (3) with a U-shaped opening and a penetration groove that traverses two interior sides and an exterior side of the buckle. A spring and a moving axle traverse across the groove. The axle is positioned by a pin (P), and a notch is formed on the axle. A semicircular groove is formed at a part connecting the buckle and the notch, and another semicircular is positioned across the buckles interior sides. The width of the U-shaped opening is determined by size of a chain before being suspended at the hook. The moving axle is positioned by a pin such that the spring is compressed by the axle and the axle does not fall from the buckle.
