Abstract:
A dual multi-bit screwdriver comprising a handle having a front handle section and a rear handle section removably interconnected together, an elongated torque transmitting shaft extends axially from a front end of said front handle section and is provided with frictional retention means, said rear handle section having a short torque transmitting shaft also provided with frictional retention means and extending axially from a front end thereof and extending within a central inner bore of said front handle section when said rear handle section is mated with said front handle section, each said torque transmitting shaft having a chuck cavity at a free end thereof for receiving a screwdriver bit in close friction fit therein, and a bit storing magazine formed in a rear wall of said front handle section and extending about said handle for storing a plurality of spaced-apart screwdriver bits in friction fit retention therein with an end portion of said bits projecting from said magazine sufficiently for removal by finger engagement, said rear handle section having cavity means to receive projection portions of said bits stored in said magazine when said rear handle section is mated with said front handle section, said front and rear handle sections are removably interconnected together by interengaging frictional clamping means, said front handle section having a plurality of flexible projecting fingers extending from a rear circumferential body portion thereof and recessed from an outer periphery thereof, said flexible projecting fingers having a transverse indent therein, said rear handle section having a plurality of flexible clamping teeth projections disposable over said fingers and frictionally engageable in respective ones of said indent, said bit storing magazine is comprised by a plurality of cavities formed in said circumferential portion of said front handle section, and at least an elongated portion of each said cavities being exposed to a portion of a more pliable thermoplastic elastomer than said rear body portion, said at least one elongated portion being an outermost wall of said cavities and forms an outer surface portion of said front handle section, said thermoplastic elastomer providing an outer friction surface to assist in torquing said torque transmitting shaft.
