When the detection block 8 is located between the two clamping plates 7-4, the two first hydraulic cylinders 7-5 work at the same time to drive the two clamping plates 7-4 to move closer to each other and clamp the detection block 8. In the present invention, clamping mechanisms 7 are provided on the opposite surfaces of the two movable plates 6-3, and the two clamping mechanisms 7 clamp the front and rear sides of the detection block 8 respectively.

[0054] Through two tests, the detector 12-2 monitors different positions around the test position, and multiple sets of detection values ​​are analyzed to improve the accuracy of the detection. In actual use, the orientation of the detector 12-2 is changed by rotating the mechanism 11, and multiple tests can be performed on the same detection position to obtain multiple sets of results.
