Cable fixer

This invention provides a cable fixing device containing a fixing unit suitable for fixedly connecting with a supporting steel cable and a clamping device which clamps at least one cable and the fixing unit connected with the cable clamping device. The cable clamping device uses a screw arbor type tension regulator beneficial to realizing convenient and realiable clamping of cable and capable of transferring environmental loads like wind, snow, etc. and its own gravity to the high-strength supporting steel cable especially eliminating the displacement of transmission lines in the longitudinaldirection due to temp. effect and securing long-time reliable work of cables and line route.
