The guide slider 88 then drives the support column 86 and the connecting rod 85 through the support seat 87 at its top, pushing the first push plate 84, so that the two sets of lower fixing parts 81 squeeze the high-voltage line, thereby adjusting the distance between the two sets of lower fixing parts 81 and fixing the two sets of lower fixing parts 81 at the lower end of the high-voltage line. At this time, according to the thickness of the high-voltage line, the operator connects the first threaded rod 832 of the locking assembly 83 to the first threaded hole 833 of the lower fixing part 81. While fixing the lower fixing part 81 and the upper fixing part 82, the upper fixing part 82 squeezes the high-voltage line, thereby achieving the technical effect of detecting high-voltage lines of different thicknesses. The detection results are then transmitted to the data terminal through the voltage sensor 5.
