The utility model has the advantages that: compared with the prior art, the method has the advantages that,

1) when the utility model is used, the minimum through hole and the maximum through hole are coaxial, and the minimum through hole and the maximum through hole are not in the same plane, so that when the device is used, only the pier head is inserted into the maximum through hole first and then inserted into the maximum through hole, and the size of the pier head can be checked whether to meet the specification only by inserting once, and the working efficiency is higher;

2) the utility model arranges the minimum through hole and the maximum through hole at the front end and the rear end of the connecting cylinder, so that the go-no go gauge structure is stable;

3) the utility model discloses a make the internal diameter of connecting cylinder increase gradually from minimum through-hole to maximum through-hole for most pier heads just are blocked by the connecting cylinder before the minimum through-hole edge of direct contact, avoid the pier heads to make minimum through-hole internal diameter grow for a long time direct contact minimum through-hole edge, make the utility model discloses the precision reduces, the utility model has the advantage of long service life;

4) the utility model can observe the position of the pier head clamped in the connecting cylinder through the observation port, thereby estimating the diameter of the pier head;

5) the utility model can directly read the diameter of the pier head through the scale;

6) the utility model connects the connecting cylinder through the small retainer ring, so that the structure of the connecting cylinder is more stable, the observation hole can not be opened because the pier head is inserted into the connecting cylinder, the size measurement of the pier head is not accurate, and the utility model has the advantages of stable structure and accurate measurement result;

7) the utility model discloses a connecting cylinder is connected to big retaining ring for the connecting cylinder structure is further more firm, can not make the observation hole open because the pier nose inserts the connecting cylinder, makes pier nose size measurement inaccurate, the utility model has the advantages of the structure is firm and the measuring result is accurate.
