CLAMPING TOOL IN FORM OF WIDE OPENING PLIERS (VERSIONS) Russian patent published in 1997 - IPC

FIELD: mechanical engineering; tools. SUBSTANCE: movable and fixed jaws 30, 14 coupled with handle 12 are provided, each, with three working surfaces 34, 36, 38 and 18, 20, 22. Line of joining of working surfaces 18, 34 is located on longitudinal geometric axis L displaced relative to axis of joint 28 connecting jaw 30 with handle 12 and passing through center of end of handle 12. Opposite working surfaces of jaws 14, 30 are asymmetrical relative to axis J arranged at angle γ to axis L and passing through axis of joint 28 intersecting line of joining of working surfaces 18, 34. Value of asymmetry is selected from relationships X/Y 0.5 where X and Y - maximum distances from axis J to working surfaces 22, 38 of jaws 14, 30. EFFECT: enlarged operating capabilities. 15 cl, 3 dwg
