Hook cutter

A hitched hook cutter for cutting off a hook hitched by foreign body during fishing has an oval framework consisting of a guide arc, a frame and a semicircular frame, wherein on the top of the oval framework is arranged an orifice through which a protection rope is tied, on the semicircular frame are fixed two blades through three bolts, and the knife edges of the two blades face the inside of the oval framework. Due to the gravity action of the semicircular frame, the three bolts and the two blades, the hitched hook cutter slides into water along a fishing rod and a main line through the limit action of the guide arc and the frame, the main line being tightened, the protection roped being pulled, the blades approaching and cutting off the sub line of the hitched hook with the main line as an axis of rotation, thereby releasing the hitched hook.
