ABSTRACT:
There is disclosed a vise clamp for a stable and precise operation. The vise clamp includes movable and stationary jaws including corresponding contact portions. The movable jaw is secured to an end of a rod. The rod is inserted through the stationary jaw in a sliding manner. A first trigger is connected to the bottom of the stationary jaw. A second trigger is connected to a handle extended from the bottom of the stationary jaw. The first trigger is operable to drive a moving device in the stationary jaw. The second trigger is operable to drive a retaining device in the stationary jaw. The retaining device consists of grip collars around the rod. The moving device includes grip collars around the rod and two linings between the grip collars and the rod. Thus, the area of the contact of the moving device with the rod is large. Hence, the operation of the vise clamp is stable and precise, and the clamping force of the vise clamp is large.
