Patent ID: 8561505

Claim:
A multiple-link tool assembly, comprising: an extension link comprising: (i) a connecting end defining a sectioned cavity comprising an internally serrated cavity section and a non-serrated cavity section; (ii) an adjustable geometric connector 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 connector into the internally serrated cavity section, such that complementary serrations of said geometric connector and said sectioned cavity engage to operatively lock said geometric connector in a selected orientation, and upon linear movement of said geometric connector 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 connector to another selected orientation; and a tool link removably joined to the geometric connector of said extension link.
