When the detection of the helical thread of the inner hole is started, the motor 3 may drive the helical thread detection device 2 to step in the inner hole along the axis 11 of the inner hole with a preset step size. So that data samples are taken at a plurality of sampling locations within the bore. For example, taking the orifice as an initial point, one datum is acquired, traveling a preset step (e.g., 10 mm) into the bore every second along axis 11.
