The present invention relates to an improved structure of a mowing disc, which is an improved design of a cutter rope wearing structure for providing a mowing mower for a lawn mower, mainly for a mowing disc assembled by a lawn mower wearing a plastic knife cord piece. The hole for the inner groove of the body for the insertion of the cutter shaft is equally divided, and the ventilation hole is reduced according to the cutting to reduce the noise, and the shape of the hole is arranged in a diamond shape to make the cutter thread wear. After being placed, the same diamond shape is extended and assembled, and the disk body is rotated to make the tapered edge of the blade member convexly form a sharp edge of the cutting edge, thereby improving the mowing efficiency and reducing the overall rotating motor load. Reduce the occurrence of noise during mowing, and ensure that the mowing surface is flat and beautiful, providing mowing operation for labor-saving and safe use.本創作一種割草盤之改良結構，係一種提供割草機用割草盤的刀繩件穿置結構改良設計，主要於割草機穿組塑製刀繩件組裝的割草盤，於盤體供刀繩件穿置用的內凹槽環緣等分設置的穿置孔，依切割減少風阻有效降低噪音之需要，將其穿置之口形設成菱形狀的排列，使刀繩件穿置後呈相同的菱形狀的伸出組裝，通過盤體旋轉動，使刀繩件錐凸的菱形角緣，形成一切割的銳利刀口緣，達到割草效率提升及整體轉動馬達負荷降低，有效降低割草時噪音的發生，並確保割草面的平整美觀，提供割草操作達到省力安全使用之目的。
