Abstract
Being useful with a rotary driving tool powered electrically or pneumatically, a fastener-driving accessory comprises a collar-mounting stem and two interchangeable collars, each being mountable coaxially and removably on the stem and being secured removably when mounted thereon. The collar-mounting stem has a collar-mounting portion having a distal end and having a polygonal cross-section. Each collar defines a stem-receiving socket, which has a similar but larger cross-section and into which the collar-mounting portion can be non-rotatably plugged. A fastener-driving collar defines a fastener-driving socket having a cross-section conforming to the cross-section of the stem-receiving socket so that the stem-receiving and fastener-driving sockets are interchangeable. A bit-mounting collar accommodates a fastener-driving bit having a socket-fitting portion, which has a polygonal cross-section conforming to the polygonal cross-section of the collar-mounting portion of the stem, and a fastener-driving portion. In one contemplated embodiment, the collar-mounting stem is connected to a tool-drivable stem, by a quill.
