  • Patent number: 5177848
    Abstract: A hand tool includes a handle section having two L-shaped legs with a pulling leg attached to each handle leg. The handle legs are pivotally attached to each other by a pivot bolt and a pusher element is attached to that pivot bolt. As the handles are squeezed together, the pulling legs are moved in one direction and the pusher element is moved in an opposite direction. Thus, a moving the handles toward or away from each other generates simultaneous pushing and pulling forces. The pulling legs can be releasably or permanently attached to the handle, and an extension element can be releasably attached to the pushing element.
