Abstract
A driving joint includes a joint block secured to an output shaft of an electric driving unit, and a U-shaped connection plate connected at its opposite ends to the joint block and provided at its front wall with an elongated connection hole. The connection plate can be engaged within the U-shaped driven joint, and the elongated connection hole can be fitted to a connection plate of a T-shaped driven joint. With this arrangement, various types of jacks having different types of driven joints can be driven by a single electric tool.
