Test pin and the second knurling handle section are provided with coaxial pilot hole；
The size of the pilot hole is identical with the outer diameter of the rigging pilotage.
Preferably, the outer diameter of the rigging pilotage is less than the outer diameter of the B sections of concentricity test pin.
Preferably, the outer diameter of the B sections of concentricity test pin according to product to be measured drawing position degree and tolerance ruler
Very little making.
Preferably, the A sections of reference pins are more than B sections of concentricity test pins, A sections of reference pins and B sections of concentricity test pins it
Between formed 0.5 degree of oblique angle.
Preferably, the surface blackening and annular knurl of the first knurling handle section and the second knurling handle section design.
Compared with prior art, the utility model has following advantageous effect：
1, the utility model is reasonable for structure, easy to operate, low manufacture cost, fabrication cycle are short；
2, the utility model can greatly improve production efficiency, reduce and scrap and produce delay cost, reduce use
