ABSTRACT:
A tool connecting device includes a shaft having a non-circular socket opening for receiving a non-circular rotatable member of a tool member to allow the tool member to be selectively tilted relative to the shaft to different angular position. A protrusion is extended from the tool member for engaging with the shaft to anchor the rotatable member to the shaft and to prevent the tool member from being tilted relative to the shaft. A control ferrule may be slidably engaged onto the shaft to selectively retain the tool member in line with the shaft and to prevent the tool member from being tilted relative to the shaft, or to allow the tool member to be slanted and tilted relative to the shaft to different angular position.
