发明名称 Weed and grass trimmer attachment head
摘要 A vegetation trimmer attachment head includes a main body, a plurality of elongated blades extending radially outward therefrom, and pins to pivotably attach the blades to the main body. A single pin cover mates with the main body to retain the pins in place. The pin cover is held in place by being interposed between the main body and the vegetation cutting device. The attachment head is simple and can be quickly disassembled and reassembled without tools because it has few parts, none of which are threaded or snap together.
