摘要： A hand tool includes a head that is adjustable to a plurality of positions. The head is pivotally mounted to a tool body at a pivot axis. A bearing structure is attached at the pivot axis by a hub or fastener, about which the head may be adjusted. An actuator is positioned between the body and the head and acts to lock the head in a predetermined position with respect to the tool body. A plurality of radial slots are provided on a cavity or a bearing structure and receive the actuator in order to lock the tool head in a predetermined position relative to the tool body. The adjustable head allows for the tool to be manipulated to engage fasteners in hard to reach areas and also allow an operator to apply extra torque to the fastener.
