Nichsskoy industry. The purpose of the invention is to simplify the design. The processed wire is installed in the area between the jaws 7.11 and 9.10. By applying force to the lever 2 and the body 1, the lever is rotated around the axis 3. The jaws align the wire and the cutting elements cut into the insulation. Then the protrusion 18 interacts with the stop 20. The axis 3 first bends the spring 17 and moves along the transverse

parts of the L-shaped groove 16. Next, the axial component of the thumb force displaces the ferrules 2 and 8 through the stop 20, the jaws 10 and 9 and the cut off part of the insulation on the wire in the longitudinal direction. The longitudinal portion of the L-shaped groove 16 limits movement. The slider 6 with the sponge 7 and the lever 8 with the sponge 9 are ecked along the guiding elements 4 and 5 along the longitudinal axis of the wire, about the core. 6 Il.

The invention relates to process equipment for the preparation of electrical wiring for installation and can be used in electrical industry.

The purpose of the invention is to simplify the design.

Figure 1 shows the device, General view, section; Fig. 2 is a view A in Fig. 1 (the mutual arrangement of the parts of the device at the time of the straightening of wire fixation and cutting of insulation) J in Fig. 3 is disassembled in Fig. 1; 4 shows a device with lodgments for transmitting force from the fingers of the hand, a general view of FIG. 5, a kinematic diagram of the device; Fig. 6 is a kinematic diagram of a device with lodgments for transmitting force from the fingers.

The device comprises a housing 1, in which a lever 2 is mounted, pivotally connected with it by an axis 3. Guiding elements 4 and 5 are made in the lever and the housing 1, in which respectively a slider 6 with a sponge and a link 8 with a sponge 9 are installed. Sponge 10 and 9 are located respectively on the lever 2 and the housing 1. Sponges 9 and 11 are installed on the axles of rotation 12 and 13, respectively, the heads 7 and 11 form the first pair 14 of straightening and fixing the wire 15 in one of the places along the length of the wire. The sponges 10 and 9 form a second pair of straightening, fixing the wire in another place along the length, cutting the insulation and displacing the cut part of it along the axis of the conductive core. In the housing 1 is made L-shaped groove 16.

The axis 3 is mounted in the groove 16 with the possibility of movement and is spring-loaded with a spring 17. On the lever 2, a projection 18 is made DLI of placing the thumb. The spring 19 serves to return the elements of the device to its original position. A stop 20 is formed on the lever 8 to form a center of rotation during operation of the device. To compensate, the difference in angular displacement is spring 21.

If the device with lodgings is used to transmit force from the fingers of the hand on the housing 1 and the lever 8, the lodgments 22 and 23 are filled to apply the efforts of the index 24 and TpeJc of the remaining 25-27 fingers.

The device works as follows.

Tractable wire 15 is installed in the area 28 between the jaws of the device. By applying force to the lever 2 and the body 1 of the jaw 7, 11 and 9, 10 the wire is straightened into a longitudinal line, the angular movement of the lever 2 relative to the body 1 is compensated by the rotation of the jaws 9 and 11 around the axes 12 and 13. insertion of cutting elements into the insulation. Spring 21 provides a tangential force applied to the wire by the elastic properties of the material. When the power in action continues with the thumb, the stop 20 in the kinematics of the device begins to perform the function of the second axis of rotation of the lever 2. At first, the axis 3 bends the spring 17 and moves along the transverse part

L-groove 16. Next, the axial force component of the thumb displaces the levers 2 and 8 through the support 20, the jaws 10 and 9 and the cut off part of the insulation on the wire being processed in the longitudinal direction, limited by the walls of the longitudinal part of the L-shaped groove 16. The slider 6 with the sponge 7 and the lever 8 with the sponge 9 slide along the guiding elements 5 and 4 along the longitudinal axis of the wire, stripping the core. The device (figure 4) is placed in the operator's hand in such a way that the thumb is placed on the protrusion 18 of the lever 2, the index finger 24 - on the lodgment 22 of the housing 1, and three fingers 25-27 - on the lodgment 23 of the lever 8.

The movement of the slider 6 and the lever 8 along the axis of the wire is carried out under the influence of three fingers 25-27 on the cradle 23.

The proposed device allows the stripping of the wire core in a strictly automatic sequence of straightening cycles and securing
