FIELD: machine building.
SUBSTANCE: locking device consists of drive of reciprocal travel connected with two parallel hinges oppositely arranged on one of working plates, notably, on movable plate; further, drive is connected with interconnected and uniformly directed links on ends of which there are secured dowels. The latter are made with segment like recesses in their lock position enveloping corresponding circumferential lugs on columns. The columns are mounted on another working plate. Also, the drive of reciprocal travel is tied with opposite directed links of parallel hinges. Via rotation axes the uniformly directed links of the hinges are connected with rods installed in guiding blocks. The rods are fixed on the blocks from the side of opposite directed links connected to the drive of reciprocal travel. The guiding blocks are made with bushings from the side of other counter directed links; the bushings are regulated relative to inter-axial distance between the rods.
EFFECT: increased service life and reliability of device.
