Patent ID: 8312795

Claim:
A multiple-link tool assembly, comprising: an extension link comprising: (i) a connecting end defining a sectioned cavity comprising a reduced-diameter internally serrated cavity section and an enlarged-diameter non-serrated cavity section; (ii) an adjustable geometric fitting comprising an externally serrated base received and retained within said sectioned cavity; (iii) a spring located within the non-serrated cavity section, and adapted for normally urging the externally serrated base of said geometric fitting into the internally serrated cavity section, such that complementary serrations of said geometric fitting and said sectioned cavity engage to operatively lock said geometric fitting in a selected orientation, and upon linear movement of said geometric fitting against a biasing force of said spring the complementary serrations of the externally serrated base and the internally serrated cavity section disengage as the externally serrated base moves into the non-serrated cavity section, thereby enabling rotational adjustment of said geometric fitting to another selected orientation; and a tool link having a proximal end removably joined to the geometric fitting of said extension link and a fastener-engaging distal end adapted for engaging a threaded fastener, whereby each selected orientation of said geometric fitting locates the fastener-engaging distal end of said tool link at a distinct notional plane of engagement relative to the threaded fastener.
