The detection body includes a first end and a second end opposite to the first end, and has a receiving cavity. The top column is slidably disposed in the receiving cavity of the detection body along the central axis of the detection body, and the top column has a first end face and a second end face opposite to the first end face. The dial indicator includes a dial head and a dial rod connected to the dial head, the dial rod is passed through the first end of the detection body and has a measuring end face, and the measuring end face is in abutment with the first end face of the top column. The spherical measuring piece is located at the second end of the detection body and is in abutment with the second end face of the top column.

If the tapered hole is not facing upward during measurement, it is inconvenient to implement. Improvements are made for this purpose. Utility Model Content
