Cutting blade body of revolution null of Brush Cutter payment

摘要

PURPOSE:To provide a cutting edge designed to reduce the number of parts and facilitate its assembly and dismantling. CONSTITUTION:A case 1 is linked to a bobbin 2 in a relatively revolvable way, a flexible linear edge 4 is externally drawn through a penetrating hole 5 enclosed only when the case 1 is fitted with the bobbin 2, and the bobbin 2 is intermittently revolved relatively to the case 1 through the behavior of an arm 3, thereby automatically delivering the flexible linear edge 4. The entire cutting edge rotator can be made up from merely two parts, the case 1 and bobbin 2, leading to such advantages as further reduction in the number of parts, improvement in the efficiency of assembly and dismantling, and also improvement in cost performance, etc.
