ABSTRACT:
A tool driver having a body with a longitudinal axis and opposite ends. A boss is positioned at one of the ends. A tool collet is positioned at the other of the ends. A plunger is positioned within a bore in the body. The body has a pair of oppositely disposed pins, at least one of the pins being movable in relation to said body in response to movement of the plunger. An actuator is positioned on and connected to the plunger. The actuator and plunger move as a unit axially of said body between an at rest position and a static position. One pin is movable between an extended position and a retracted position as the plunger and actuator move between an at rest position and a static position, whereby a tool can be positioned on the tool driver when the plunger and actuator are in their static position and held in operable position on the tool driver when the plunger and actuator are in their at rest position.
