This creation is a kind of related Yu Hook structure of what,It is that Yu Yu Hook main body forms one and extends and be bent pointed cone portion upward down,And the what pointed cone portion side is equipped at least one of guide groove,Thereby,Using this, at least one of guide groove is designed,Fish blood can be made to flow out along guide groove,Effectively to discongest fish Blood denseness and tension force effect,Cause Yu Hook insertion fish body or by fish body extract resistance,And reach when fish being made to bite bait,Shi Yu Hook is smoothly inserted into fish body,And when what removal Yu Hook,Convenience is by fish Hook by benefits such as fish body extractions.本創作係有關於一種魚鈎結構，係於魚鈎主體成型有一往下延伸且彎曲朝上之尖錐部，並於該尖錐部側面設有至少一道導槽，藉此，利用該至少一道導槽設計，即可使魚兒血液沿著導槽流出，以有效疏解魚兒血液黏滯度及張力作用，造成魚鈎在插入魚體或由魚體拔出的阻力，而達到使魚兒咬住魚餌時，使魚鈎順利插入魚體內，以及於卸除魚鈎時，便利將魚鈎由魚體拔出等效益。
