ABSTRACT:
A multiple bit screwdriver includes a tubular handle body with a first end portion, an opposite second end portion and an axial bore formed through the first and second end portions. A plurality of tool bits are inserted successively into the axial bore via the first end portion such that the tool bits are rotatable with the handle body, and are removable successively from the axial bore via the second end portion. Each of the tool bits has a bit portion and a connecting sleeve on one end of the bit portion. The connecting sleeve has an axial blind hole formed therein to permit extension of the bit portion of an adjacent tool bit therein. First and second spring units are respectively provided on the first and second end portions and extend radially inward into the axial bore. The first spring unit engages frictionally and resiliently the connecting sleeve of a first one of the tool bits that is located in the first end portion of the handle body so as to prevent the tool bits from falling out of the first end portion. The second spring unit engages frictionally and resiliently the connecting sleeve of a second one of the tool bits that has the bit portion thereof extending out of the second end portion. The second spring unit prevents the tool bits from falling out of the second end portion.
