A weight block is formed by two sides with thickness which are not parallel and extend upward from one bottom face. One side of the intersection of the sides extends upward to form a tip, the other side of the intersection faces the center of the bottom face to form a holding groove, and the other end section away from the tip is a U-shaped surface, which is characterized in that each side extends from the top to the bottom respectively at corresponding positions At least one fixing through hole shall be threaded.First, the hook is inserted into the fish body, and then the chin of the dead bait is fixed in the holding groove through the fixing holes and the fish nostrils through the fishing line. Because the gravity center of the weight block is downward, the dead bait can balance the fish body, make the dead bait swing flexibly like a live fish, and then achieve the effect of a real live bait.一重量塊，係由一底面向上延伸不平行且具有厚度之二側面一體成形而成，各該側面交集之一側邊向上延伸形成一尖端，交集之另一側邊朝向該底面中央下凹形成一容置槽，且遠離該尖端之另一端截面為一U形面，其特徵在於：各該側面分別於相對應位置處由上而下穿設至少一固定透孔。首先，先將魚鉤塞入魚體內，再將死餌之魚下巴透過釣魚線穿過各該固定透孔及魚鼻孔固定於該容置槽內，使用時由於該重量塊重心向下，因此能平衡魚身，使死餌像是活魚般靈活擺動，進而達到擬真活餌之效用。
