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.
Claims10
A clamping device comprising
- a. 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;
- b. an inner fulcrum member positioned between and supporting said clamping members so as to enable said clamping members to pivot about said inner fulcrum member, said inner fulcrum member also being positioned between the ends of each of said clamping members;
- c. an outer retaining ring surrounding and supporting said clamping member at positions diametrically opposed to that of said inner fulcrum member so as to pivotally retain said clamping members with respect to said inner fulcrum member;
- d. a tapered member disposed within a space defined by and located between said clamping guide sections of said clamping members, said member having a tapered outer peripheral surface arranged such that when said tapered member is displaced to move said tapered outer peripheral surface into contact with inner surfaces of said clamping guide sections, said clamping guide sections are moved away from each other thereby forcing said clamping jaw sections to move toward each other by pivotal movement of said clamping members about said inner fulcrum member, the clamping force at said clamping jaw sections being increased as the displacement of said tapered member is increased.
