Such a positioning member 2 has a simple structure, is convenient and quick to manufacture and assemble, and has a low manufacturing cost. Preferably, a clamping groove 2011 is provided on the limiting boss 201. In this way, when the three-coordinate inspection fixture of the utility model is used to inspect the plastic-coated steel wire bus 3, the steel wire 33 located at the middle positioning hole 31 and the end positioning hole 32 in the plastic-coated steel wire bus 3 can be clamped in the clamping groove 2011, thereby improving the stability of the plastic-coated steel wire bus 3 when it is pressed on the three-coordinate inspection fixture of the utility model, and improving the inspection efficiency.
