Abstract:
A fastener driving kit useful with a rotary driving tool powered electrically or pneumatically, comprising:a collar-mounting stem, said collar-mounting stem defining an axis and having a collar-mounting portion having a polygonal cross-section;a fastener-driving collar, said fastener-driving collar defining an axis and two axially aligned sockets, each socket having a polygonal cross-section, which is larger than the polygonal cross-section of the collar-mounting portion, the cross-sections of the collar-mounting portion being of a given geometry and of the axially aligned sockets being of said given geometry, the axially aligned sockets being interchangeable to serve respectively as a stem-receiving socket and as a fastener-driving socket, the collar-mounting portion being adapted to be non-rotatably plugged into whichever socket serves as the stem-receiving socket so as to mount the fastener-driving collar coaxially on the collar-mounting stem, wherein said fastener-driving collar has two opposite ends and one continuous passage defining the axially aligned sockets, extending between the opposite ends, and having a polygonal cross-section conforming to the polygonal cross-sections of the axially aligned sockets;means for securing the fastener-driving collar removably on the collar-mounting stem when the collar-mounting portion is plugged into whichever socket serves as the stem-receiving socket; anda bit-mounting collar, which is useful when the fastener-driving collar has been removed from the collar-mounting portion, the bit-mounting collar having two opposite ends, namely a stem-receiving end and a bit-mounting end, the bit-mounting collar defining a stem-receiving socket opening at the stem-receiving end and having a polygonal cross-section, which is larger than the polygonal cross-section of the collar-mounting portion of the collar-mounting stem, the bit-mounting collar having an axial passage extending between the bit-mounting end and the stem-receiving socket of the bit-mounting collar and having a circular cross-section with a cross-sectional area smaller than the cross-sectional area of the polygonal cross-section of the stem-receiving socket of the bit-mounting collar.
