Signal line linkage

The utility model relates to a signal line linkage, including main shaft, neodymium iron boron magnetism ring, base and the horizontal pole of axial assembly in proper order, wear to be equipped with to reach the standard grade on the horizontal pole clamping piece and the clamping piece that rolls off the production line, upper and lower fastener piece steps up the wire from top to bottom between the fastener piece through the pulling force of straining spring. The utility model discloses a signal line hangs fixing device, can adsorb on metal surface, increases the degrees of freedom of signal line, and the different wiring modes that can adapt to under the various test conditions make the signal line can avoid the ground wiring selectively, produce insulated thermal insulating's effect between signal line and production facility pipeline.
