A kind of conductor loop construction of fishing rod includes: a chimeric ring with the first perforation and hole wall. One change for being pivoted what first perforated inner, is provided with one second perforation at the change center, and the big what of change outer diameter is fitted into the first punch inside diameter of ring, and the middle section of change outer wall corresponds to the hole wall width of first perforation and is set as groove. The lead ring of one fixed what second perforated inner is provided with third perforation at the lead ring center. The change can drive lead ring what be fitted into ring first perforation in pivot, the setline for passing through chimeric ring is then worn when loading pulling force, because lead ring rotation can mean exposure third perforate inner wall, it is greatly reduced setline and pinpoints the probability contacted with lead ring, not only increase the service life of lead ring, it is not required to frequent restringing ring construction when more because fishing, causes the enjoyment enhancement of fishing of fisherman.一種釣竿之導線環構造，包含：一具有第一穿孔及孔壁之嵌合環。一樞設於該第一穿孔內部之轉環，該轉環中心處設置有一第二穿孔，且轉環外徑大於嵌合環之第一穿孔內徑，並轉環外壁之中段對應該第一穿孔之孔壁寬度設為凹槽。一固設於該第二穿孔內部之導環，該導環中心處設置有一第三穿孔。該轉環可帶動導環於嵌合環之第一穿孔中樞轉，則穿貫嵌合環之釣魚線在負載拉力時，因導環之轉動可平均接觸第三穿孔內壁，其大幅降低釣魚線與導環定點接觸之機率，不僅增加導環之使用壽命，更因垂釣時不需經常更換導線環構造，致使釣魚者之垂釣樂趣增進。
