This scheme adopts the count type of leading to no-go gage structure to survey the utensil, adopts the shift fork shaft hole 3 of the high position precision with former basic input shaft dead eye 2 with coordinate system, a clamping processing as new benchmark, the effectual position precision who guarantees the terminal surface. The measuring tool comprises a measuring rod 4, a reference rod 5 and a sleeve 8, wherein one end of the reference rod 5 is provided with a first matching surface 5-1 which can be inserted into a shifting fork shaft hole 3 and tightly matched with the bottom of the hole, the lower end of the measuring rod 4 is provided with a second matching surface 4-1 which can be inserted into a steel ball hole 1 and tightly matched with the reference rod 5, the upper end of the measuring rod 4 is provided with a go gauge end 6 and a no-go gauge end 7, the sleeve 8 is sleeved at the upper end of the measuring rod 4, the lower end of the sleeve 8 is provided with a third matching surface 8-1 which can be tightly matched with the end surface of the steel ball hole 1, and the upper end of the sleeve 8 is arranged to be a reference surface 8-2.

When the device is used, a front casing shell to be measured is placed on a platform, the steel ball hole 1 is ensured to be vertically upward, the reference rod 5 is inserted into the shifting fork shaft hole 3, the first matching surface 5-1 is closely matched with the bottom of the hole, the measuring rod 4 is inserted into the corresponding steel ball hole 1 from top to bottom, the second matching surface 4-1 is closely matched with the reference rod 5, then the sleeve 8 is pressed downwards to enable the third matching surface 8-1 to be closely matched with the end face of the steel ball hole 1, whether the reference surface 8-2 at the upper end of the sleeve 8 is higher than the go gauge end 6 and lower than the no-gauge end 7 is detected in a mode of eye watching or finger touching, if yes, the height of the end face of the steel ball hole 1 is qualified, and if no, the steel ball hole 1 is unqualified.
