The measuring ruler 14 is provided with a scale number. Since the lengths of the fixed plate 1, the connecting plate 17 and the fitting ring 18 are the same, it is only necessary to observe the position of the moving block 16 on the measuring ruler 14 to calculate the pipeline diameter. Since two pairs of measuring rulers 14 are provided, it is convenient to measure the diameters of the inner wall of the pipeline at multiple angles to observe whether the inner diameters of the pipelines are the same.

Embodiment 2: In embodiment 1, there is still a problem that the measuring device cannot be folded and stored. Therefore, based on embodiment 1, this embodiment further includes:
