This creation system provides a kind of structure of uniaxial winder,System includes pedestal and line wheel,The hollow inside of pedestal that wherein pedestal has is to be formed with to place space,And inwardly transferred by base perimeter and be extended with axle bed,And be transversely provided with a what on axle bed and place shaft in space,And be the axis hole being axially arranged on socket what shaft at the body center that line wheel has,It is formed at the upper what axis hole outer periphery of its ontology between opposite ring-type frame and two frames and forms the wire casing of receiving for fishline winding,And set grip part upper annular arrangement is formed with plural ejection face on two frame of what,When the hand of user is held on the fishing rod that pedestal outside foot prop combines,It can push the ejection face of what grip part that line wheel be made to carry out Quick winding movement and more light and laborsaving using thumb,Either thumb cooperation index finger grasps on the grip part of two frame of what line wheel the gripping strength increased to line wheel respectively,Effectively to control the length outside fishline pull-out what line wheel.本創作係提供一種單軸捲線器之結構，係包括有座體及線輪，其中該座體所具之基座中空內部為形成有穿置空間，並由基座周邊處向內轉折延伸有軸座，且軸座上橫向設有位於穿置空間中之軸桿，而線輪所具之本體中央處為軸向設有套接於軸桿上之軸孔，其本體上位於軸孔外側周邊處形成有相對之環狀邊框及二邊框間所形成可供釣線纏繞之納線槽，並於二邊框上所設之握持部上環狀排列形成有複數推頂面，當使用者的手部握持於基座外側處腳架所結合之釣竿上時，便可利用姆指推動於握持部之推頂面使線輪進行快速捲線動作且更為輕鬆而省力，或者是姆指配合食指分別抓握於線輪二邊框之握持部上來增加對線輪的握持力量，以有效控制釣線拉出於線輪外之長度。
