However, in this device, "the working end of the gauge body is provided with coaxial through ends and stop ends in sequence along the axial direction of the gauge body," and the structures of the through ends and stop ends are relatively fixed, and the detection apertures of the through ends and stop ends cannot be flexibly adjusted according to actual detection requirements. While the scope of application is limited, the gauge body is relatively small in size, which is inconvenient to pick up during detection, and reduces the detection operation efficiency, which has disadvantages. Summary of the invention
