Vise clamp

A vise clamp comprising:

• a stationary jaw (30);
• a rod (20) inserted through the stationary jaw (30);
• a movable jaw (10) secured to the rod (20);
• a moving device (40) put in the stationary jaw (30), the moving device (40) comprising a plurality of grip collars (43) around the rod (20), two linings (41;
• 42) between the grip collars (43) and the rod (20), and a spring (45) for pushing the grip collars (43) so that the grip collars (43) are perpendicular to the rod (20) in order to release the rod (20);
• a first trigger (38) connected to the stationary jaw (30) and operable to tilt the grips collars (43) relative to the rod (20);
• a retaining device (50) put in the stationary jaw (30), the retaining device (50) comprising a first grip collar (51) around the rod (20), a second grip collar (52) put around the rod (20) and formed with a hunch (520) for abutment against the first grip collar (51), a third grip collar (53) around the rod (20), a spring (55) for pushing the first grip collar (51), and a lever (54) extended from the third grip collar (53), wherein the first and third grip collars (51;
• 53) are normally tilted relative to the rod (20) in order to grip the rod (20);
• and
• a second trigger (37) connected to the stationary jaw (30) and operable to push the third grip collar (53) through the lever (54) so that the third and first grip collars (53;
• 51) are perpendicular to the rod (20).
