With further movement rod 15 last ceases to contact with the cones 13 and 14 of the levers 1 and 2 and through the axis 17 and two shoulders lever 18 t there is no down cheeks 11 and 12 levers 1 and 2, which through cylindrical rods 5 and 6 press cheeks 7 and 8 to the body 4, depriving the mobility of the levers 1 and 2 in the axial direction, as well as the possibility of rotation and movement. Such fastening of the workpiece does not violate its position, held under the action of the main clamp, since the described design features allow the levers 1 and 2 to be self-mounted. The device is designed to add an additional JQ to the workpiece by mounting the small head 20 of the connecting rod with the force of the spring itself. at 21, the main mount of which is not shown along the big head 22.
