Abstract:
A screwdriver comprising:an elongated hollow handle having a central bore that is formed therethrough and that has first and second end portions;a plurality of bits disposed removably on the handle;a first retaining device;a first sleeve having a central bore that is formed therethrough and that has two hexagonal-cross-sectioned end portions of different sizes, the first sleeve having two ends, one of which is mounted removably within the first end portion of the central bore in the handle by the first retaining device, the one of the ends of the first sleeve being capable of being removed forcibly from the handle so as to mount the other one of the ends of the first sleeve removably within the first end portion of the central bore in the handle by the first retaining device;a second retaining device;a second sleeve having a central bore that is formed therethrough and that has two hexagonal-cross-sectioned end portions of different sizes, one of which is mounted removably within the second end portion of the central bore in the handle by the second retaining device, the sizes of the end portions of the central bore in the second sleeve being different from those of the end portions of the central bore in the first sleeve, the one of the ends of the second sleeve being capable of being removed forcibly from the handle so as to mount the other one of the ends of the second sleeve removably within the second end portion of the central bore in the handle by the second retaining device;a connecting rod extending axially and movably through the handle and having first and second end portions that extend respectively into the first and second sleeves, each of the first and second end portions of the connecting rod having an end surface that is formed with a hexagonal-cross-sectioned bore;means for retaining the connecting rod on the handle; andmeans for locking the connecting rod releaseably at a first position, where the first end portion of the connecting rod extends to a position between the ends of the first sleeve so that the first sleeve functions as a wrench and where a portion of the second end portion of the connecting rod projects from the second sleeve so that the hexagonal-cross-sectioned bore in the second end portion of the connecting rod can receive one of the bits for functioning as a screwdriver, and a second position, where a portion of the first end portion of the connecting rod projects from the first sleeve and where the second end portion of the connecting rod extends to a position between the ends of the second sleeve so that the hexagonal-cross-sectioned bore in the second end portion of the connecting rod can receive one of the bits for functioning as a screwdriver and so that the second sleeve functions as a wrench.
