Finally, the detected result will be presented on the surface of the reporting machine through the transmission line. Since the rotation of the rotating bolt 23 is within a controllable range, the advancing speed can be adjusted according to the detection requirements, so as to effectively ensure the accuracy of the detection result. At the same time, an electric telescopic rod 15 is arranged at the lower end of the pin insertion box 14, and the height can also be adjusted according to different test pins, thereby increasing the applicability of the device.
