Abstract: A tool coupler and extender mechanism for affording greater leverage on a wrench. The tool coupler and extender mechanism includes a coupling member having a generally flat first side and a generally flat second side and having a definite thickness and further having a plurality of tool retaining members integrally extending outwardly from the first side and being adapted to retain a wrench between themselves and the coupling member. The coupling member also has a boss securely and conventionally disposed upon the second side with the coupling member further having a bore extending through the boss and through the first side and being adapted to receive a drive member of a socket wrench.
