Abstract: There is disclosed a vise clamp that can provide a large clamping force and be operated stably. The vise clamp includes a stationary jaw, a movable jaw connected to the stationary jaw, and a clamping device connected to the movable jaw. The clamping device includes a contact element moved up and down under the control of a lever. Two pinions are connected to the lever. Two pushers are provided besides the pinions. Each pusher includes a rack engaged with one of the pinions. The contact element is put against the pushers. As the lever is pivoted, the pinions are rotated. As the pushers are moved up by means of the pinions, the contact element is pushed up by means of the pushers. Thus, a workpiece can be clamped between a contact portion formed on the stationary jaw and the contact element connected to the movable jaw. Hence, the clamping force is large and the operation is stable.
