Lever lock clamp

A clamp comprising first and second jaws which include clamping surfaces that face each other;

• the jaws being pivotally attached for their clamping surfaces to pivot toward and away from one another around a pivot axis;
• a threaded screw supported to the first jaw and extending to the second jaw in a direction transversely to the direction of the pivot axis;
• a locking lever screw threadedly supported on the screw and engageable with the second jaw, such that rotation of the locking lever around the screw with the screw held to prohibit its rotation and with the locking lever engaging the second jaw, moves the locking lever against the second jaw for moving the second jaw selectively toward and away from the first jaw as the locking lever is respectively rotated in a first and second direction;
• first engagement means on the first jaw and cooperating second engagement means on the screw, such that when the first and second engagement means are in engagement, the screw is prohibited from rotation by that engagement;
• the screw being shiftable axially with respect to the first jaw for separating the second engagement means from the first engagement means, thereby freeing the screw for rotation with respect to the first jaw, such that upon rotation of the screw with respect to the lever, the axial position of the lever along the screw is adjustable for adjusting the orientation of the lever with respect to the second jaw in any particular degree of separation of the clamping surfaces of the jaw;
• and the screw also being shiftable axially for engaging the first and second engagement means.
