In FIG. 22-23 shows a diagram of the operation of the device. A buckle, characterized in that it is formed by sheaths made in the form of a housing 1 (Fig. 15-16), which includes a front wall 2 and a back wall 4 connected to it to form a gap 3 (Fig. 14).

In the gap 3 of the housing 1 are fixed, with the possibility of extraction, two knives 5 and 6, each of which has a handle 7 and, in the continuation of the handle, a bifurcated blade 8 with a longitudinal gap 9 with a width a and a round hole 10 at the end of said longitudinal gap 8, whose diameter or width is greater than the width and longitudinal clearance 9.

Each of the knives has edge protrusions 11 with slots 12 (Fig. 2, 17-19), while the blades 8 of the knives are placed inside the housing 1 in the gap 3 between the front and rear walls 2 and 4. The arms 7 of the blades 8 are located on the sides of the housing 1 .

On the front wall 2 of the housing 1 is located a rotary handle 13, which includes a Central locking longitudinal element 14, a limiter 15 of the angle of rotation of the handle, the safety element 16.

Spring extractors 17 are fixed on the rear wall 2, made in the form of two spatially curved V-shaped spring elements in plan, each of which has a twisted spring ring 18 and two branches 19 connected to the spring ring 10 at the end of each of the said branches, a bend 20 is made, located in the gap 3 with the possibility of engagement with the slots 12 of the edge protrusions 11 of the knives 5 and 6, for which, in the rear wall 2 of the housing 1, slots 21 are made to pass the said bends 20, and the branches 19 of the spring extractors 17 directed at an angle upward towards the slots 21, and the buckle has a fastening means to the belt 22 and 23. Preferably, the slots are made curved, to prevent jamming of curved V-shaped in terms of spring elements, the end parts of which during operation of the device move along curved paths.

Four slots 20 are made in the rear wall 2 of the housing 1, each to accommodate the limb 20 of a separate branch 19 of the spring extractor 17.

The central fixing longitudinal element 14 is made in the form of a turned rod perpendicularly connected to the rotary handle 13. The rod has longitudinal grooves 24, due to which its cross section has a large width d and a smaller thickness c, which allows it to rotate the rotary handle 13 and installing the rod with a large size (width d) across the longitudinal gaps and block the knives inside the holes of 10 knives.

The knives are unlocked and make the extension of the knives 5 and 6 from the housing 1 under the action of spring extractors 17 when the rotary handle 13 is rotated through an angle of 90 °, when the rod of the fixing longitudinal element 14 is set to a large size (width d) along the longitudinal clearances of the knives, while the thickness from the rod does not exceed the width and the longitudinal clearance of each knife.

The central fixing longitudinal element 14 has on its end part a central annular transverse groove 25 for mounting the bracket fixing the pivot handle 26, while the bracket, as well as the spring extractors 17 are covered with a protective cover 27, which is bolted to the back wall with bolts 28 (Fig. 5) around which are twisted rings 18 spring extractors 17.

The branches of the spring extractors 17 have a broken configuration and consist of several parts: the first parts 29 are a continuation of the twisted spring ring 18, the second parts 30 are a continuation of the first parts 29 and have bends 20, which are a continuation of the second parts 21 and form with the second parts 30 G- shaped configuration.

The rotary handle 13 is made in the form of a flattened truncated cone and has bevels 31 on its lateral side, on which means improve adhesion to the user's hand, for example, protrusions, notches, notches, corrugations, or combinations thereof.

The device operates as follows (Fig. 22-23). The rotary handle 13 is turned to the “open” position due to the fact that the rod of the fixing longitudinal element 14 is set to a large size (width d) along the longitudinal clearances of the knives. For accurate circular movement of the rotary handle on its inner side there is a limiter 15 of the angle of rotation of the handle, which is located in the guide of the radial slot 32, providing rotation of the handle by an angle of 90 °. After rotation, the rotary handle 13 is fixed in a predetermined position by the safety element 16, which is made in the form of a spring ball or other spring element. Moreover, for fixing in the desired position in the frontal wall 2, two through holes 33 and 34 are made, the diameter of each of which is smaller than the diameter of the spring ball (Fig. 4, 15). Installation in a predetermined position is accompanied by a soft click. The knives are inserted into the housing 1 and squeezed with the thumb and forefinger overcoming the resistance of the spring extractors 17 until their protrusions 35 and 36 (Fig. 17, 18) come into contact with the front wall 2 of the housing 1.

In this case, the holes in the knives are combined with each other and with the hole 37 in the front wall 2 of the housing 1 for passing the central fixing longitudinal element 14. After that, the rotary handle 13 is rotated 90 ° clockwise and the spring-loaded ball is not fixed in the hole 34 in closed position, while the rod in the combined holes 10 of the knives is set to a large size (width d) along the longitudinal clearances of the knives, blocking them. To extract the knives, turn the handle counterclockwise by 90 °.
