Principle of work:
When utilizing the solution of the present invention three to measure the dimensional accuracy of diameter of bore of parts, after two clamp pawls on first and second clamp handle of internal calliper (two back ofs the body and the back of the body over against clamp pawl) are adjusted what a size (crossing end or not-go-end), lock with a screw, then two clamp pawls on the 3rd, the two clamp handles (two back ofs the body and the back of the body over against clamp pawl) are adjusted another size (not-go-end or cross end), with another screw three clamp handles are locked together, once detect crossing of part endoporus rapidly and accurately simultaneously and hold and two sizes of not-go-end.
When utilizing the solution of the present invention four to measure the dimensional accuracy of outside diameter of parts, after two clamp pawls on first and second clamp handle of external callipers (two test side over against clamp pawl) are adjusted what a size (crossing end or not-go-end), lock with a screw, then two clamp pawls on the 3rd, the two clamp handles (two test side over against clamp pawl) are adjusted another size (not-go-end or cross end), with another screw three clamp handles are locked together, once detect crossing of part endoporus rapidly and accurately simultaneously and hold and two sizes of not-go-end.
The solution of the present invention one can only once detect crossing of part endoporus rapidly and accurately and hold or size of not-go-end.
The solution of the present invention two can only once detect crossing of part cylindrical rapidly and accurately and hold or size of not-go-end.
