A kind of low resistance buoy,Including a floating body and a plastic catheter,The floating body has one of perforation two opposite sides jack and a profile groove,The outer diameter of the big what fishline of the width of the profile groove and the aperture of the small what jack,And the profile groove is extended through the one side of the floating body by the jack,The plastic catheter have a protrusion,One insertion section,One pore and a fine crack,The outer diameter of the protrusion big what jack,The insertion section extends from the one side of the protrusion,And for being inserted into the jack,The pore and the fine crack are penetrated into the end face of the insertion section by the end face of the protrusion,The pore for accommodate fishline what wherein,The small what fishline of the width of the fine crack and the protrusion and the one side of the insertion section are extended through by the pore,The fine crack can elasticity be flared to and be enough to pass through for fishline； By above structure system make it have dismounting quickly,It is simple and the effect of facilitate.一種低抗力浮標，包括一浮體及一塑膠導管，該浮體具有貫通兩相對側之一插孔及一剖溝，該剖溝的寬度大於釣線的外徑而小於該插孔的孔徑，且該剖溝由該插孔貫穿到該浮體的一側面，該塑膠導管具有一凸部、一插入部、一管孔及一細縫，該凸部的外徑大於該插孔，該插入部延伸自該凸部的一側面，且可供插入該插孔中，該管孔及該細縫由該凸部的端面貫通到該插入部的端面，該管孔可供容納釣線於其中，該細縫的寬度小於釣線且由該管孔貫穿到該凸部及該插入部的一側面，該細縫可彈性張開至足以供釣線通過；藉由上述結構係使其具有拆裝快速、簡單及方便之功效。
