The present invention of employing technique scheme compared with prior art surveys chi and fixes under it, match above the Down Highway of measured workpiece and the following survey chi, match above the following and measured workpiece of last survey chi, can read the tapering of institute's survey conical surface, it measures convenient, save time, measurement result is accurate.
As improvement of the present invention, described orienting lug is L type and symmetrically arranged side plate and a dividing plate by two and constitutes, and this dividing plate is contained between two blocks of L type side plates, and the mutually concordant setting in last plane of the last plane of this dividing plate and biside plate.
As improvement of the present invention, the stepped structure of described second bearing pin, its first ladder embeds in the center pit of described master calibration plate, the link of first ladder and second ladder is set with described secondary scaleplate, its second ladder linearly-shape that camber line-straight line-camber line is formed by connecting, its outer packing ring that is set with, the center pit of this packing ring is corresponding with the shape of second ladder, its the 3rd ladder is the thread end of described second screw thread, is set with described second set nut on the thread end of this second screw thread.
Second ladder linearly-shape that camber line-straight line-camber line is formed by connecting, it is outer to be set with packing ring, the center pit of this packing ring is corresponding with the shape of second ladder, prevents when second set nut compresses secondary scaleplate, secondary scaleplate is rotation together thereupon.
