  • the pin (9) abuts on the facet (5) of the bar (1) and makes the stationary jaw (8) pivot clockwise about the axle (7) until the pin (9) rises on the bar (1).
  • the stationary jaw assembly (2) further moves along the bar (1) to the left until the pin (9) reaches the groove (4) on the bar (1), after which the stationary jaw (8) pivots counter-clockwise about the axle (7) due to the stretching force of the springs (10), the pin (9) enters the groove (4) and fixes the stationary jaw assembly (2) to the left end of the bar
  • the user places the workpiece between the jaws (8) and (16). While holding the drive (21) and the rear (17) handles of the movable jaw assembly (3), the user forcibly pushes the drive handle (21) to the rear handle (17) due to which the drive handle (21) pivots about the housing (15) and clamps the drive levers (18) by means of the pin (24) fixed on the handle (21). As a result, the drive levers (18) turn relative to the bar (1) and fix on it, becoming a support for the further movement of the movable jaw assembly (3).
  • the further turn of the drive handle (21) which is limited on the right by its contact with the rear handle (17), causes the movable jaw assembly (3) to move along the bar (1) towards the stationary jaw assembly (2), clamping the workpiece between the jaws (8) and (16).
