[0017] Such as Figure 3~Figure 5 As shown, it includes a connecting rod 23, a through-end measuring block 21 and a stop-end measuring block 22; the two ends of the connecting rod 23 are symmetrically provided with slots; the through-end measuring block 21 and the stop-end measuring block 22 are ring-shaped and pass through The connecting piece is rotatably supported in the slots 231 and 232 at both ends of the connecting rod 23. The outer diameter of the through-end measuring block is equal to the lower limit of the throat diameter of the position to be measured, and the outer diameter of the end-end measuring block is the same as the outer diameter of the position to be measured. The upper limit of the throat diameter of the points is equal. Specifically, the connecting piece is a pin. The shaft of the pin is provided with an optical shaft part and threaded parts located on both sides of the optical shaft part. The optical shaft part and the through-end measuring block 21, sto...
