Abstract
A battery powered tool includes a housing adapted to carry a battery. A shaft having first and second ends is connected to the housing at the first end thereof. A first mechanical joint is adapted for rotatably receiving and supporting an attachment. The first mechanical joint is mounted at the second end of the shaft. The first electrical connector contained within the first mechanical joint is adapted to cooperate with a second electrical connector in the attachment to provide electric thereto. A first electrical conductor extends within the shaft from the housing to the first electrical connector for carrying electric current from the battery to operate the attachment. A second electrical connector engages with the first electrical connector, and is connected to a boom. A second electrical conductor extends within the boom, and the other end of the boom carries a hedge trimmer, a line trimmer, a pruner, a blower or an extension.
