The invention relates to the plastic metal working, in particular to a manual instrument for metal bar cutting. The metal bar cutting shears contain two plates, levers with blades, fixed between them and installed with the possibility of turning round the pins, and two-arm bent handles. The detachable blades are fixed into the grooves of the levers and made in the form of a regular triangular prism. Disposed against each other, the ends of the small arms of the handles are articulately combined with an end of the tie-rod. Into one of its plates onto the inner side thereof there is made a groove, wherein it is freely placed the other end of the tie-rod. Each plate is made in the form of a polyhedron.Claims: 2Fig.: 3 |
