Abstract
A modular screwdriver includes an elongated hollow handle, a first sleeve, a second sleeve, and a connecting rod. The first and second sleeves are mounted removably on two ends of the handle. The connecting rod extends through the handle, and can be locked releasably at a first position, where one of the first and second sleeves functions as a wrench, and a second position, where the other one of the first and second sleeves functions as a wrench. Each of the first and second sleeves has a central bore, which is formed therethrough and which has two hexagonal-cross-sectioned end portions of different sizes. All of the end portions of the central bores in the first and second sleeves are different from each other in size. Because either of the ends of each of the first and second sleeves can be mounted removably on the handle, each of the first and second sleeves can be inverted. As such, the screwdriver has four wrench units of different sizes.
