An improved artificial bait, which is composed of metal chain, fish-shaped head and body of fish; wherein metal chain is connected in series with chain link pivoted based on end hole and axial pivot; fish-shaped head is composed of two half sectioned body, concave and protruding point for embedding are respectively set on its combining surface, groove of stopping edge is also formed at end part connecting body of fish; body of fish is formed by several blocks made in separated part, concave and protruding point for embedding are made on combining surface of block, slot connecting groove at two ends are also set, stopping edge is then made at end side of groove; based on this structure combination, metal chain can caulk with slot and groove by use of the difference formed between single link and double links, so that block can be put together with each chain part, and stopping edge may make spacing between chain part of metal chain, therefore, the rotation of axial pivot of metal chain can control the connected fish-shaped head and body of fish to sway, which may promote flexibility and strength of artificial bait.
