[0002] The wiring harness is the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and wiring harness capacity. In addition, when processing the wiring harness, a wiring harness fixing mechanism is often used to make the wiring harness placement more stable.

[0003] The existing patent document with publication number CN 220155272 U provides a wire harness fixing mechanism for wire harness terminal processing. The mechanism rotates the bolt to make the connecting plate move up and down during the rotation of the eccentric wheel, thereby adjusting the distance between the first anti-slip clamping plate and the second anti-slip clamping plate, so as to facilitate the clamping and fixing of wire harnesses of different diameters. Although the beneficial effect of this structure is significant, the following problems still exist: the eccentric wheel rotates along the bolt as the axis, and the bolt is fixed and tightened. After all, there is no other structure to lock and limit the stay angle of the eccentric wheel. Due to the persistent pressure applied by the upper connecting plate, it is difficult to ensure that a certain offset error will not occur. In addition, tightening the bolt to fix it inevitably requires cumbersome operation steps. For this reason, we propose a wire harness fixing mechanism for wire harness terminal processing.

The guide rod 13 plays a stable guiding role in the relative movement of the two sets of U-shaped frames 11 along the grooves at both ends of the bidirectional screw 12. The handles 5 installed on the top of the two sets of upper connecting plates 14 are used to assist in pulling the upper connecting plates 14 upward.
