Abstract:
A tool driver for use with a torquing mechanism, said driver comprising:a shaft having a predetermined length, a first end, and a second end, and a hollow core extending axially therein; said first end operatively connected to said torquing mechanism and having an axial opening communicating with said hollow core; said second end having a first drive terminal to said second end and a second drive adjacent said first drive; said first drive having a predetermined first cross-sectional dimension whereby said first drive can releasably engage any one of a first set of standard tool bits, said first drive further comprising a first detent protruding from said first drive capable of frictionally engaging a bit of said first set of standard tool bits, said first detent being in communication with said hollow core; and said second drive having a predetermined second cross-sectional dimension whereby said second drive can releasably engage any one of a second set of standard tool bits, said second drive further comprising a second detent protruding from said second drive capable of frictionally engaging a bit of said second set of standard tool bits, said second detent being in communication with said hollow core; a cam positioned in said hollow core, said cam capable of being moved between a first position and a second position whereby when said cam is in said first position said first and second detents are urged in a direction radially outward from said shaft and when said cam is in said second position said first and second detents are not urged in said direction, wherein said cam is moved between said first position and said second position by a cam lever extending radially from said hollow core; and wherein said first cross-sectional dimension is not equal to said second cross-sectional dimension.
