ABSTRACT:
This invention relates generally to a garden tool quick handle connector and relates more particularly to a connection structure for quick connection of a handle to a garden tool wherein inner convex threads of the handle are conveniently arranged to engage with outer convex threads of the handle connector. A special retaining plate is movably provided to serve as a stop to maintain the handle in its engaged position with the garden tool and to protect the connection against torsional force.
