With the increasing level of automotive electronics, the complexity and importance of wiring harnesses are also growing. However, existing automotive wiring harnesses still face many unresolved issues in practical applications. For example, during vehicle operation, vibration, temperature changes, and the influence of the external environment can easily lead to loosening, wear, or unstable connections in the wiring harness. These problems not only affect the reliability of the electrical system but may also pose safety hazards, adversely impacting the overall performance and safety of the vehicle. Furthermore, the design of existing wiring harnesses often presents operational inconveniences during installation and maintenance, increasing production and repair costs. Although some technical solutions attempt to improve the stability of wiring harnesses by modifying their structure or materials, these solutions typically only optimize for specific problems and fail to comprehensively address the stability and durability requirements of wiring harnesses under complex operating conditions. Therefore, developing an automotive wiring harness that can effectively improve stability, adapt to diverse operating environments, and facilitate installation and maintenance has become an important research direction in the current technological field.

In particular, the synergistic effect of the base and top seat, combined with the multi-layered protective design of the insulating pad, significantly improves the overall stability of the device, preventing loosening due to vibration or external forces. Simultaneously, the combined design of the screw and connecting rod enables highly flexible height adjustment to accommodate different specifications of automotive wiring harnesses, meeting diverse installation needs. The linkage design of the sliding cylinder, rotating rod, pulley, and transmission belt achieves efficient conversion from rotation to linear motion, ensuring precise clamping of the wiring harness and improving work efficiency. The design of the limiting frame and sliding frame, through precise control of the range of motion, avoids overload or offset, thereby improving the safety of the device. The design of the connecting cylinder and connecting rod further enhances the stability of the overall structure and extends the service life of the device. In summary, the technical solution of this utility model provides important technical support for improving the stability and reliability of automotive wiring harnesses by optimizing structural design and functional configuration.
