Problem to be solved: to provide a structure for removing the knuckles at the time of Octopus fishing in Octopus fishing, and a structure in which the needle part of the hook is hard to hang.The principle of the pulley that moves in the opposite direction to the direction, the structure of the link, and the construction of the mechanism which utilizes the lever principle are pulled by pulling it in the pulling direction, and it is able to move it in the direction to remove the root which was carried out once, and it is able to cancel the root hanging, and also, it is The position of the needle at the bottom of the foot is removed from the seabed, and it is able to move it off in the direction to remove the knack that has been carried out once, and it is able to cancel it.Also, the trick is a structure in which a needle protrudes when the octopus is attached to the trick and the octopus is removed.Diagram【課題】蛸釣りに於ける蛸釣り時に根掛りをした仕掛けを外す手段、仕掛けの針部が根掛りし難い構造を提供する。【解決手段】根掛りをした蛸仕掛けを引き上げ方向に引っ張ると仕掛けは該方向とは反対方向に動く滑車の原理とリンクの構造と梃子の原理を駆使した仕掛けの構成は、一度根掛りした仕掛けを外す方向に動かして根掛り解除することが出来、又、該仕掛けの着底後引きずる時の針の位置を海底から離した仕掛けにして、一度根掛りした仕掛けを外す方向に動かして根掛り解除することが出来る構成とし、根掛りし難い構造にした。又、該仕掛けは、該仕掛けに蛸が抱き付くと針が突き出て蛸を仕留める構成である。【選択図】図1
