Embodiment

Embodiment one: the special measuring tool of 10 ° of conical surfaces of HFS-10 handle is comprised of two measurers, namely a measurer L-HFS10-ZX(is referring to Fig. 1 and Fig. 2) and No. two measurer L-HFS10-ZD(referring to Fig. 3 and Fig. 4), two measurers all comprise measurer main body and clock gauge (referring to Fig. 8 and Fig. 9).

Figure 10-Figure 13 is each view structure of a measurer main body, and Figure 14-Figure 17 is each view structure of No. two measurer main bodys.The structure of two measurer main bodys is basic identical, difference only is that the height that the conical surface is detected is different, utilization is used for calculating taper value to the detection numerical value of conical surface differing heights, determines by the taper value of detection computations and the relation of standard value whether the detected conical surface is qualified.

Number in the figure 1X is a measurer main body, 1D is No. two measurer main bodys, 11X is top conical surface hole, 11D is conical surface hole on the lower, 12X and 12D are for measuring end face, hole centered by 13X and the 13D, 14X and 14D are the measuring staff jack, 2X and 2D are respectively clock gauge, 21X and 21D are fixed sleeving, 22X and 22D are side lever, and 23X and 23D are the bulb contact pin, and 24X and 24D are dust cap, 3X and 3D are respectively the M4 jackscrew, 31X and 31D are respectively top wire hole, and 4 is test product, and 41 is the conical surface (the tested conical surface) of test product.
