Spiral fishing hook

A spiral fishing hook comprises an upper connector and a hook body connected on the upper connector, wherein the hook body is in a spiral shape, and a spiral screw on one end of the hook body smoothly approaches to an axial cord of a fishing hook to overlap with the axial cord finally to form a hook tip with taper. The spiral fishing hook can firmly grasp rope type falling objects which are pressed into conglobation and fall into deep well, super deep well or small well holes especially, and can not surge, and can effectively lift and fish out rope type falling objects. Once the hook can not be lifted and clamped, the fishing hook only needs rotating reversely, and the spiral fishing hook can escape easily to drop out fallen fish. The fishing hook has simple structure and convenient manufacture.
