Yi Seed Rubber bellows sinkers include one first fastener, one second fastener and a counterweight. The first fasteners of The have one to block Machine Agencies processed in the first Body of hollow Like and one the oneth. The second fasteners of The have one to block Machine Agencies processed in the 2nd Body of hollow Like and one the 2nd. The mutual Right of the Body With The the 2nd of The the first Body energy connects and Wai Wound go out an accommodating sky Inter, and the cards of The first cards of Machine Agencies With The second processed Machine Agencies Only processed disposably blocking Hou can not divide From. The Pei Chong Jian Let set what The accommodating Kong Inter Inner, and the specific gravity of The counterweights is the specific gravity of big what water. Hou Bu Fen From Knot Agencies Let Meter are mutually clamped by engagement the second fasteners of Jian With The of The first, just what filling Ge Seed counterweights of in addition to 鉛, Bu Dan Ring guarantors can also reduce material cost.一種膠囊式沉子,包含一第一接合件、一第二接合件,及一配重件。該第一接合件具有一呈中空狀的第一本體,及一第一卡制機構。該第二接合件具有一呈中空狀的第二本體,及一第二卡制機構。該第一本體與該第二本體能互相對接而圍繞出一容置空間,且該第一卡制機構與該第二卡制機構僅能一次性卡制後不分離。該配重件設置於該容置空間內,且該配重件的比重是大於水的比重。藉由該第一接合件與該第二接合件的互相卡制後不分離的結構設計,便於填入除了鉛以外的各種配重件,不但環保亦可降低材料成本。2‧‧‧第一接合件21‧‧‧第一本體211‧‧‧環腰部22‧‧‧第一卡制機構221‧‧‧第一嚙合部23‧‧‧第一頸部24‧‧‧第一端部3‧‧‧第二接合件31‧‧‧第二本體32‧‧‧第二卡制機構321‧‧‧第二嚙合部33‧‧‧第二頸部34‧‧‧第二端部4‧‧‧配重件
