Abstract
Portable, hand held, battery operated, hydraulic tools are provided with a tool frame and one or more interchangeable working heads. When the working head is connected with the tool frame, a piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task. A coupling mechanism holds the working head to the tool frame. The coupling mechanism allows the working head to be removed from the tool frame and another working head to be joined to the tool frame. The coupling mechanism can hold the working head at a fixed rotational angle with respect to the tool frame. The coupling mechanism can also allow the working head to rotate with respect to the tool frame.
