The utility model relates to a structure of a line connecting piece, which at least comprises a connecting body having a connecting part for the combination of buoys and a through connecting part； the through connecting part is provided with a hole for the bus bar to pass through, and a gap is cut from the bottom of one side upward to connect with the hole, and the transverse depth of the gap is cut to the position of the central line, so that the bus bar can be connected with the connecting body and the buoys after passing through the hole In order to improve the stability of the buoy, the same center line is formed, which can effectively reduce the superiority of the wind shaking.一種線上連結件結構，其至少包含一連結本體具有一供浮標結合的結合部以及一穿結部；該穿結部貫設有一供母線穿設的穿孔，並由一側底部朝上剖設一缺口與該穿孔連通，且該缺口橫向深度係剖設至中心線位置，以使該母線穿設穿孔後能與連結本體及浮標連結形成同一中心線位置，具以提高浮標連結穩定性有效降低風力晃動誤判就餌發生之優異性。
