This creation is a kind of structural improvement of related weeding disk,Main system is made of the straw rope that removes of a turntable and a winding what turntable,Wherein,Turntable sets cell wall by cell wall group on one,And it is formed with an annular groove,And rim of cell wall is equipped with two groups of corresponding C font notches on this,And what C font notch it is corresponding under cell wall be equipped with a pillar； It is improved in what: the pillar system is a bolting element,Cell wall is equipped with a screw hole under corresponding to below,And plural gasket is equipped with above what screw hole,And the pillar system can cooperate except straw rope size selects different size of nut spiral shell to consolidate in what screw hole； When implementation,It can allow except straw rope positions between what gasket and pillar,And according to except straw rope thickness adjustment pillar height and select different-diameter size nut,The phenomenon that prevent from causing de- rope under high speed rotation is its purpose person.本創作係有關一種除草盤之結構改良，主要係由一轉盤及一纏繞於轉盤之除草繩所構成，其中，轉盤係由一上槽壁組設一下槽壁，並形成有一環槽，而該上槽壁之緣邊設有二組相對應之C字形缺口，並於C字形缺口所對應之下槽壁設有一凸柱；其改良在於：該凸柱係為一螺固元件，其下方對應之下槽壁設有一螺孔，並於螺孔上方設有複數墊片，而該凸柱係可配合除草繩粗細大小選擇不同大小的螺帽螺固於螺孔內；實施時，可讓除草繩定位於墊片及凸柱間，並依除草繩粗細調整凸柱高度與選擇不同直徑大小的螺帽，以防止高速旋轉下造成脫繩的現象為其目的者。
