A pair of opposed L-shaped jaw spacers at their one ends are pivotally connected together and upon the jaw body. A pair of links at their one ends are pivoted to the clevis and at their other ends are pivotally connected respectively to the other ends of the jaw spacers. Each of the jaw spacers has a central jaw link projecting therefrom. A pair of jaw arms at their inner ends are nested within the jaw links respectively and selectively welded thereto at a predetermined included angle for a particular clamping function.
