Interchangeable head boring or driving apparatus

Abstract

A new and improved interchangeable head boring or driving apparatus includes a first head-receiving member which includes a first polygonal-shaped receiving well which is in alignment with a longitudinal axis of the head-receiving member. A plurality of respective interchangeable head assemblies include respective head elements and respective projections which project from the head elements. The respective projections include a first polygonal shape complementary to the first polygonal-shaped receiving well. The respective projections project from the head elements, such that, when the respective projections are inserted into the first polygonal-shaped receiving well, the respective projections and the first polygonal-shaped receiving well arc coaxial along the longitudinal axis. A locking assembly locks the respective projections into the first polygonal-shaped receiving well of the head-receiving member. The first polygonal-shaped projection and the first polygonal-shaped receiving well may have respective cross-sectional shapes of a quadrilateral, a triangle, a hexagon, or a semicircle, among others. The interchangeable head assembly may include a screwdriver blade portion. The screwdriver blade portion is connected to a projection. A flexible belt retainer assembly is provided for a plurality of interchangeable head assemblies and includes a flexible belt member, complementary belt connecting straps attached to the flexible belt member, a plurality of receivers for receiving the head-receiving members, and a plurality of receivers for receiving the interchangeable head assemblies, whether they be for interchangeable drill bits or for interchangeable screwdriver blades.
