Description: |
The key features that allow parallel jaw motion are the elongated slot for one of the handle "pivot" points, and the tongues to guide the sliding movement of one jaw.
Alternative constructions shown includes provision for a central tongue rather than paired tongues, for a wire cutter, for a thumb screw to clamp the jaw setting, and for a spring to return the jaws to "normal open" position. |
