There is a ring groove on the bushing (2), an end of the lever (1) projected into the ring groove, the other end of the lever (1) forms a pedal extending down out of the fixed vice body (4). The present invention has advantages of operating easily and work-clamped exactly, by applying a pre-clamping force on a work through a foot-pressing force.
