The utility model relates to a buoy improved structure, which uses a tubular through end section to connect with a target body section with a plurality of upper through holes, lower through holes and cross through holes, and combines with the target foot section by means of the upper through-hole extension, and the lower part of the said target body section is provided with an extension slot to combine with the target foot section, so as to form a device with low water resistance, high sensitivity, wind resistance and wave resistance, fast in and out operation, instant punctuation and obvious fish information. Buoy structure.一種浮標改進結構,係以一管狀貫通之標尾段,使與一具有複數上通孔、下通孔、橫通孔的標身段,藉上延接通孔結合,前述標身段下方設一下延接槽孔使與標腳段結合,形成一種備具低水阻、高靈敏度,具抗風、抗浪,且進出作合快速、即時標點定置、魚訊明顯之浮標結構者。
