Disclosed is a sinking rope for fishing net. A modulized chain thread has a plurality of sinkers in serial connection with equal pitch. Each sinker has a body where a neck portion and an end portion are integrally connected from each of both ends of the body. Therein, the neck portion is smaller than the body and smaller than the end portion in radial cross sectional dimension. A braided wire covers the modulized chain thread by interlocked braiding way. Each of the modular grips has a flexible wire and a plurality of waterdrop-shaped hollow catchers connected from two ends of the flexible wire. The hollow catchers have U-shaped notch groove to clamping the necks. Accordingly, by simple operation of assembling rapid connectors, the sinkers and the modular grips are rapidly chained to form a modulized chain thread as a core wire for braiding a sinkingrope by circular knitting machine to realize automatic manufacture.揭示一種漁具沉子繩。模組串接芯等距串接有複數個沉子,每一沉子具有一本體,由本體之兩端皆一體連接有一頸部與一端部,其中頸部之徑向剖切尺寸係小於本體之徑向剖切尺寸且亦小於端部之徑向剖切尺寸。編織包覆繩以交錯編織的方式包覆模組串接芯。利用模組扣接器具有一可曲折線體與兩端連接之複數個水滴形挖空扣體,挖空扣體具有U型缺口扣槽,以扣接頸部。因此,利用以快速連接頭方式的簡單動作,沉子與模組扣接器能快速的接合成一條模組串接芯,來作為圓編機之中心線進而包覆成漁具沉子繩,達到自動化製作。110‧‧‧模組串接芯130‧‧‧沉子131‧‧‧本體132‧‧‧頸部133‧‧‧端部140‧‧‧模組扣接器141‧‧‧可曲折線體142‧‧‧挖空扣體143‧‧‧U型缺口扣槽144‧‧‧扣點
