Driving tool having rotatable coupling

A driving tool comprising:

• a tool stem including a non-circular spatial engaging member provided on a first end thereof and having at least one flat surface formed therein,
• a tool shank including a first end having a non-circular socket opening formed therein and having at least one curved surface formed therein for pivotally receiving said spatial engaging member of said tool stem and for engaging with said at least one flat surface of said non-circular engaging member of said tool stem and for allowing said tool shank to be selectively tilted relative to a longitudinal axis of said tool stem to different angular position, and said tool shank including a second end for coupling to a tool member, and
• a control ferrule slidably engaged onto said tool shank for being held by a user, and said control ferrule being slidable and selectively engageable onto said tool stem for retaining said tool shank in line with said longitudinal axis of said tool stem and for preventing said tool shank from being tilted relative to said tool stem to other angular position, and said control ferrule including a magnetic member disposed therein for attracting a tool element to said control ferrule.
