ABSTRACT:
A clamping device especially adapted for use with an automotive body or frame straightening device is disclosed wherein at least two clamping members each having a clamping jaw section at one end thereof and a clamping guide section at the other end thereof are held together by a retaining ring in such a manner that they may pivot about a ball disposed inwardly thereof, and within the space defined by the clamping guide sections is disposed a tapered member which has an outwardly tapered outer peripheral surface. When the tapered member is drawn or pulled outwardly, its tapered outer surface forces the clamping guide sections to move away from each other while forcing the clamping jaw sections to move toward each other, whereby the strong clamping force is produced.
