[0016] Preferably, a spring is fixedly connected between the limit block and the circular ring frame.

[0017] The effect achieved by the above components is that the limit block is attached to the surface of the leather case under the elastic force of the spring.

[0027] Reference Figure 1-4 As shown, the utility model provides a technical solution: an anti-tear cable, comprising a leather cover 1, and a plurality of wire cores 2 are inserted into the leather cover 1.

[0028] The following is a detailed description of its overall specific settings and functions.

[0029] In the present embodiment: the end side of the leather case 1 is covered with a circular frame 3, and the inner thread of the circular frame 3 is connected with three bolts 4. The three bolts 4 inside the rotating circular frame 3 can realize the limiting work of the cable ports of different sizes. The inner side of the circular frame 3 is fixedly installed with a fixed block 7, and the end side of the fixed block 7 is fixedly connected with a circular block 8. The circular block 8 can be placed on the middle position of the cable, further improving the anti-downward movement effect of the wire during use. The surface of the circular block 8 is fixedly connected with a fixed pin 9, and the side wall of the fixed pin 9 is rotatably connected with a plurality of spacers 10. The setting of the spacer 10 can also be placed on the end side position of the cable to avoid the movement of the circular frame 3. The inner sliding connection of the circular frame 3 is provided with three sliders 5, and the end side of the slider 5 is fixedly connected with a limited block 11, and the inner side of the limited block 11 is provided with a notch with a cross section of a "V"-shaped structure. The notch of the "V"-shaped structure improves the tightness of the limited block 11 and the middle of the cable.

[0030] Specifically, a plurality of arc-shaped thorns 12 are fixedly connected to the inner side of the limit block 11. When the wire core 2 is subjected to the external force pulling force moving away from each other, the barbs will be inserted into the inner side of the leather case 1, which can avoid the continued downward movement of the circular frame 3. A spring 13 is fixedly connected between the limit block 11 and the circular frame 3. The limit block 11 will be attached to the surface of the leather case 1 by the elastic force of the spring 13. A rubber strip 6 is glued to the inner side of the circular frame 3. The rubber strip 6 is provided to avoid direct friction between the wire core 2 and the inner side of the circular frame 3, thereby avoiding severe wear of the wire core 2.

[0031] Working principle: the staff can unfold the partition 10 on the fixing pin 9 according to the number of wire cores 2 in use, and the partition 10 can separate the wire cores 2 at the port position of the leather case 1. After the circular ring frame 3 is put on the port position of the leather case 1, the three bolts 4 inside the circular ring frame 3 are rotated to realize the limiting work of cable ports of different sizes. The limiting block 11 will be attached to the surface of the leather case 1 by the elastic force of the spring 13. When the wire cores 2 are pulled away from each other by an external force, the barbs will be inserted into the inner side of the leather case 1, which can prevent the circular ring frame 3 from continuing to move downward, thereby preventing the cable from being torn along the port position, and improving the stability of the use of the wire. The rubber strip 6 is set to prevent the wire core 2 from being torn from the inner side of the circular ring frame 3. Direct friction between the wire cores 2 is achieved, thereby avoiding serious wear of the wire core 2 and extending the service life of the wire core 2. By separating the wire cores 2, it is possible to avoid the wire cores 2 being pressed against each other, making it inconvenient to dissipate heat, further improving the performance of the cable. The circular block 8 can be placed in the middle of the cable, further improving the anti-downward movement effect of the wire during use, thereby avoiding the downward movement of the cable sheath 1. The partition bar 10 can also be placed against the end side of the cable to avoid the movement of the circular ring frame 3. By setting the above structure and shielding the cable port position by setting the circular ring frame 3, it is possible to prevent the cable sheath 1 from being torn at the port position, thereby extending the service life of the cable to a certain extent.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
