The principle of this programme is such: the ring gauge below base body is ring standard gauge, play the effect of calibration, during use, the inspection in workpiece aperture has come by the method that the hole with ring standard gauge compares, when the diameter of institute's gaging hole and required value have error, the dynamic measurement pin be fixed on dop is mobile, and drive the double leval jib affixed with dop to move, because is provided with volute spring between double leval jib and dop, volute spring can make dop be pressed in all the time on the inwall in hole, and double leval jib be displaced through third connecting rod hinged successively, second connecting rod and first connecting rod are delivered on the sounding rod of concatenation pointer, thus make pointer point out error amount in dial plate, stage clip fixing between first connecting rod and second connecting rod can guarantee that dynamic measurement is sold, double leval jib, second connecting rod and third connecting rod are in the position contacted all the time.
Preferably, the diameter of described second connecting rod is greater than the diameter of first connecting rod, compression spring sleeve is located on first connecting rod, and the two ends of stage clip are respectively on the end face being located at internal cavity body wall and second connecting rod, make stage clip can stable being set on first connecting rod, and make dynamicly to measure pin, double leval jib, second connecting rod be in third connecting rod the position contacted all the time.
Preferably, described dial plate is provided with transparent plastic jacket, and transparent plastic jacket neither hinders reading, can play again effect that is dust-proof, protection pointer.
Preferably, described quiet measurement pin is fixed by screws on base body, and quiet measurement pin is on the inner hole wall being located at workpiece, and screw connects, easy installation and removal.
