This creation is a kind of structural improvement of buoy, especially a necking section is set under the buoy body, which can be used for winding lead sheet, lead wire and other weights, so as to change the draft of the buoy, and promote the buoy tail floating on the water surface to be sensitive to the fishers.本創作係一種浮標結構改良，尤指於浮標的標身下方係設有一頸縮段，俾而可供鉛片、鉛線等配重進行纏繞，藉以改變浮標的吃水深度，促令浮於水面的標尾可以靈敏反應魚訊者。
