Abstract

In order to enhance the availability of tools, a multi-function tool includes a handle having first and second ends with the first end having an opening for receiving a screwdriver tip, and the second end having an opening for receiving a tube which is releaseably retained in relation to the handle by a collet. The handle has opposed side openings extending from the second end to a point near the collet. The tube is mounted for limited axial sliding movement relative to the handle from a position where one of its ends is retained by the collet to a position where it is no longer retained by the collet to position the tube in alignment with the side openings in the handle. The tube is also mounted for pivoting movement when it is in alignment with the side openings to a generally transversely extending position. The tube cooperates with the handle in the generally transversely extending position to define a T-shaped handled for applying increased torque to the first handle end. With this construction, a screwdriver tip is also operatively associated with each of the ends of the tube to project outwardly of the second end of the handle when the other of the ends of the tube is retained by the collet.
