Secondly, the design of spring and bolt increases the complexity of the device, not only the process requirement is high in the manufacturing process, the cost rises, but also it may be loose, aged or failed due to long-term use, thereby reducing the fixing performance. In addition, the hoop shape formed on the inner side of the cable of this structure is relatively single, only suitable for standard circular cross-section cables, and has poor adaptability to other shapes such as flat cables or special cross-section cables, and the use range is limited. In summary, the current cable fixing device has deficiencies in structure compactness, applicable scenarios, manufacturing cost and diversified adaptability, which needs to be improved and optimized.
