WORKPIECE RISING PREVENTION STRUCTURE OF A VISE FOR RESTRICTING A PORTION OF WORKPIECE FROM FLOATING IN GRIPPING FIRMLY THE WORKPIECE BETWEEN MOVABLE AND FIXED JAWS BY SUPPLYING RETURN FORCE BY A LEAF SPRING
PURPOSE: A workpiece rising prevention structure of a vise is provided to maximally repress floating of a workpiece by changing the direction of floating force in gripping the workpiece by a movable jaw with reaction force generated by self-return force of a spring member. CONSTITUTION: A workpiece rising prevention structure of a vise(1) is composed of a base body unit(10) of the predetermined length for placing a workpiece(2) on the upper surface and a guide rail unit(11) disposed longitudinally; a fixed jaw(20) fixed to one end of the upside of the base body unit to support and engage the workpieces; a movable jaw(30) mounted on the upside of the base body unit to move horizontally; a slider(40) fixed and installed to the movable jaw and settled to the guide rail unit of the base body unit to move horizontally along the guide rail unit; and a screw bar(50) rotatively combined to the slider to move the slider horizontally. The slider has a spring member(60) installed to the guide rail unit of the base body unit.
