ABSTRACT:
A clamping device for a key duplicating machine includes two pairs of fixed jaws and movable jaws arranged on a base, and can be relatively moved to each other along two horizontal parallel upper and lower guide rods. The fixed and movable jaws are provided with several vertical semicylindrical notches of different radii on the confronting sides thereof in order to form several vertical approximate cylindrical clamping holes for clamping cylindrical keys of different diameters when the movable jaws are moved toward the fixed jaws. An upright biasing device is provided on the base beneath a horizontal portion of the fixed and movable jaw. The biasing device includes a pivotable location stopper arranged on the fixed jaw and has a horizontal plate portion arranged in a pre-determined level position. The biasing device further includes an upright cylinder and a compression spring received in the cylinder for upward biasing of a cylindrical key blank or an original key to be clamped against the horizontal plate portion.
