摘要： A tool driver including a shaft having a longitudinal axis and opposite ends. A first partial boss is located at one of the shaft ends, a tool collet at the other of these shaft ends, and a second partial boss having a bore extending therethrough. The second partial boss being positioned on the shaft with the shaft in the bore. There is a stop on the shaft. The second partial boss is slidable on the shaft between the first partial boss and the stop. A spring is positioned between the second partial boss and the stop. The spring urges the second partial boss into engagement with the first partial boss. The first and second partial bosses are complementary to each other and are in engagement with each other defining a bayonet type latch mechanism. The latch mechanism has an axially extending inwardly tapered bore extending from one end coaxially of the shaft into the first and second bosses. The tapered bore being adapted to receive a coaxially located disc of a tool and to be connected to the tool driver within the tapered bore. The tapered bore and the tool disc coaxially centering the tool on the axis of the tool driver.
