Cable fixing mechanism for railway communication

The invention discloses a railway communication cable fixing mechanism which comprises a base, a telescopic rod is fixedly installed in the middle of the top of the base, a transverse plate is fixedly installed at the top of the telescopic rod, a rotating disc is rotationally connected to the middle of the top of the transverse plate, and a fixing device is fixedly installed at the top of the rotating disc. By the adoption of the structure, the lead screw is matched with the rotating shaft, when the distance needs to be adjusted, the driving crank is rotated to drive the lead screw to rotate, the lead screw drives the threaded ring on the outer surface to move, the position of the threaded ring can be adjusted at the moment, and meanwhile the threaded ring on the surface of the rotating shaft is moved to the lead screw according to needs; in this way, on one hand, the number of the fixing assemblies can be freely adjusted according to the number of the cables, on the other hand, the distance between the cable
