Description

Technical Field

[0001] This utility model relates to the technical field of cable clamping mechanisms, and in particular to a cable clamping mechanism for electrical installation engineering. Background Technology

[0002] Cables are characterized by internal conductivity and external insulation. They are categorized into various types, including power cables, control cables, and signal cables. During electrical installation projects, a large number of cables need to be suspended and installed. Cable clamping mechanisms are typically used to hold these cables in place. Existing cable clamping mechanisms generally have multiple cable positioning components, but the distance between these components cannot be adjusted, thus preventing adjustment of cable tension. Furthermore, significant temperature differences in different seasons cause fluctuating cable tension, potentially leading to cable breakage in winter. This results in limited applicability of cable clamping mechanisms. Summary of the Invention
