Abstract
A multiple-link tool assembly includes an elongated handle, an exchangeable extension link, and an exchangeable tool link. The exchangeable extension link has a first connecting end removably linked to the handle, and a second connecting end defining a sectioned cavity. The sectioned cavity includes an internally serrated cavity section and a non-serrated cavity section. An adjustable geometric connector having an externally serrated base is received and retained within the sectioned cavity. A spring is located within the non-serrated cavity section, and is adapted for normally urging the externally serrated base of the geometric connector into the internally serrated cavity section. The exchangeable tool link has a proximal end removably joined to the geometric connector of the extension link, and a fastener-engaging distal end adapted for engaging a threaded fastener.
