Cutting head for lawn trimmer |
摘要 |
A cutting head for a lawn trimmer is provided and consists of a cylindrical housing block bolted to a lower portion of the lawn trimmer so that the housing block is rotatably mounted thereto. A flexible cord with a knot at center of the cord is placed within an opening of the housing block with ends of the cord extending outwardly through each of a pair of opposed holes at side of the housing block. When the lawn trimmer is turned on the knot will retain the cord within the block. In another form a sleeve is mounted securely on the cord to retain the cord in the block.
