Patent ID: 7481136

Claim:
A tool device comprising: a tool member including a three-dimensional engaging member provided on a first end thereof and having at least one curved surface formed therein, a shaft including a first end having a non-circular socket opening formed therein and having at least one flat surface formed therein for pivotally receiving said engaging member of said tool member and for engaging with said at least one curved surface of said non-circular engaging member of said tool member and for allowing said tool member to be selectively tilted relative to a longitudinal axis of said shaft to different angular position, and said shaft including a second end having a non-circular engaging hole formed therein for receiving a first driven member, a control ferrule slidably engaged onto said shaft, and slidable and selectively engageable onto said tool member for retaining said longitudinal axis of said shaft in line with said tool member and for preventing said shaft from being tilted relative to said tool member to other angular position, a sleeve slidably attached to said second end of said shaft, and including a non-circular opening provided in a first end portion of said sleeve for selectively engaging with a second driven member, said sleeve being rotatable in concert with said shaft for allowing said first and said second driven member to be selectively driven by said shaft and said sleeve, and said sleeve including a peripheral flange formed therein, a spring member engaged between said shaft and said sleeve for biasing said sleeve relative to said shaft, and a retaining ring engaged onto said shaft and engageable with said peripheral flange of said sleeve for limiting said sleeve to slide relative to said shaft.
