摘要 |
A quick-change drill chuck adapted for positioning ball elements within dimples circumferentially disposed about the central axis of the adapter portion of a tool, such as a drill, to drive the drill. A first quick-change drill chuck utilizes an axially spring-biased collar, while a further quick-change drill chuck incorporates a rotary spring-biased collar for manipulating the ball elements into and out of the dimples.
