  • Patent number: 6722040
    Abstract: An adapter for a weed eater is movably connected to a lower side of a spinning spool of a weed eater. The adapter when installed to the weed eater has a cord equal in height to weeds after they are cut. A center of the seat of the adapter has a penetrating hole. A stud penetrates through the penetrating hole of the adapter so as to lock the spinning spool of the weed eater. Since the diameter of the penetrating hole is larger than the diameter of the stud, the adapter and the spinning spool are movable connected to one another, and the adapter can move along the stud. The weight of the weed eater can be transferred to a ground so as to reduce the burden of the user and the weed eater can avoid stones as it is trimming weeds.
