Claims

30 proposed tool, general view; in fig. 2 is a section AA of fygg) in FIG. 3 - view B on fit. 1, the tool includes a housing 1 in which L-shaped knives 3 and 4 are mounted on the axis of rotation 2. A rotary clamping jaw 5 is installed on the axis of rotation of the housing, a Hg-shaped clamping jaw 6 is filled in one piece. with the body. A npv spacing is installed between the blades 3 and 4 (gum 7, A cutting edge is made at the ends of the working surfaces of the gripping jaws. The gripping jaws and cleaning knives are set up with their walls to form a single cutting jig, 8. The Eccentric 9 is rigidly connected to the handle 10 and has an axis of rotation 11. The levers 12 and the pull 13, together with the spring 14, form the horizontal movement mechanism for the stripping knives. The spring 15 serves to return p 10 s. eccentric 9 to its original position. The working surface of the eccentric is made in an Archimedes spiral, passing into a circle in the area corresponding to the location of the jaws in a closed state. The tool works as follows: In the initial position of the spring 7 and The QL4 is in a free state, the cleaning knives 3 and 4 are separated, and with them the clamping bolts 5 and B. The drive, from the end of which it is necessary to remove the insulation, is inserted between the clamping jaws 5 and 6 and the cleaning blades 3 and 4 to the required depth. Then, pressing down the handle 10, the force is transmitted through the eccentric 9 and overcoming the force of the spring 7, the clamping jaws 5 and 6 and the stripping knives 3 and 4 are brought down to the stop. When ets n the sharp edges of the clamping jaws 5 and 6 and the stripping knives 3 and 4 cut into: r insulation to a predetermined depth, and the locking elements 8 thus gash the wire and guide its axis arally to the longitudinal axis of the nstrum. -The convergence of sponges and knives is ensured by making the starting section of the eccentric profile in a spiral) rhimeda. Continuing further rotation of the handle 10 around the axis 11 until it comes into contact with the levers 12, they are moved apart. compressing the spring 14j and together with it moving and pulling 13, which in turn moves the cleaning knives 3 and 4 from left to right and tightens the notched insulation of the central conductor of the wire. In this case, the further convergence of the clamping jaws and s, the cleaning knives is not due to the fact that the next section of the profile of the eccentric is made along the circumferential tee. Lowering the handle 10 returns the system to its original position. Such a constructive performance of the tool eliminates damage to the insulation with clamping jaws, which rioBlie the quality of wire processing; Claim 1. Instrument for isolation from wires, comprising a housing with a handle, in which L-shaped clamping jaws and stripping G-155 knives are installed on the axle on the axles and connected to the grips via the knife-moving mechanism along the wire characterized in that, in order to improve the quality of wire processing by eliminating deformation of the insulation of the wire, cutting edges are made at the ends of the working surfaces of the clamping jaws, while the jaws and stripping knives are set coaxially with the possibility of contact with their walls, forming a single cutting edge. 2, The tool according to claim 1, which includes an eccentric mounted on the handle and interacting with the press. sponges; the working surface of which is made in the spiral of Archimedes, transition to the circumference of the area corresponding to the location of the jaws in a closed state.
