The rotation of the rotating seat 17 realizes the rotation of the conductive member 8, and then the conductive elastic sheet 13 on the conductive member 8 passes through a plurality of conductive bases 12 distributed in a circular array. And due to the elasticity of the conductive elastic sheet 13, the conductive elastic sheet 13 can tightly fit the conductive base 12 at the position to be measured. Then, the pressing on the insulating shell 5 is released, and the insulating shell 5 rises and resets to make the conductive plate 16 fit the surface of the conductive member 8, that is, the test circuit is conducted.
