ABSTRACT:
A drive adapter for use with a first wrench including a first type drive lug of a first size and for use with a second wrench including a second type drive lug of a second size. The drive adapter comprises a main body including a first end, a second end and an axial hole therethrough. The first end includes a hole of a first size adapted to receive the first wrench first type drive lug while the second end includes a hole of a second size adapted to receive the second wrench second type drive lug. The drive adapter further comprises a rod including a first type drive lug of a first size and a second type drive lug of a second size where the rod first type drive lug is adapted to slideably engage the main body first end hole and the rod second type drive lug is adapted to slideably engage the main body second end hole so that the rod is repositionable along the main axial body hole. In a first mode of operation, the rod is selectively moveable to a first operative position wherein the rod first type drive lug extends outward from the main body and the rod second type drive lug is recessed inside the main body so that the second wrench may be operatively connected to the main body second end hole. Similarly, in a second mode of operation, the rod is selectively moveable to a second operative position wherein the rod second type drive lug extends outward from the main body and the rod first type drive lug is recessed inside the main body so that the first wrench may be operatively connected to the main body first end hole.
