Abstract

A spring tool having a first arm pivotably and slidably connected to a second arm. The lower ends of the both the first and second arms are adapted to selectively retain an end of a spring so that the tool may be used to install an energized spring onto a part. The first arm includes a lower end having a window that the lower end of the second arm may pass through. The upper ends of the arms may be manipulated to pivot about a pivot point moving the lower ends of the arms together energizing a spring connected to the arms. The ends of the spring may become overlapped as the lower end of the second arm passes through the window. One arm may be moved upwards with respect to the other arm to make it easier to connect the overlapping ends of the spring around a part.
