Detection monocline probe beam axis offset angle not should be greater than 2 °.So in the present embodiment：The angle of angle α is 2 °.
In the present embodiment：Dipping 12 is isosceles trapezoid, and dipping 12 is the trapezoidal bottom with the part that centering plate 11 is connected
Side.Measurement side 13 is needed to be gone by probe 2 from 2 left and right sides of probe in the detection method being mentioned above, and two measurement sides 13 or so
Symmetrically.When cubing 1 is by centering plate 11 and the centering of test block 3, and from 2 or so two ends of probe by pop one's head in 2 when, the isosceles trapezoid of dipping 12
Two waists conform exactly to symmetrical requirement.
The beneficial effect of this programme is：If the only one measurement side 13 of cubing 1, and will be from probe 2 or so two when detecting
End is alignd, it is necessary to overturn cubing 1 with probe 2, makes the measurement side 13 for leaning against 2 both sides of popping one's head in symmetrical；And work as dipping 12 for etc.
When waist is trapezoidal, it is not necessary to overturn cubing 1,2 other ends of probe are moved to, detection efficiency can be improved compared with the former.
