15. According to the invention, the inner side wall of the pipeline is supported by the air bag, so that the external positioning space can be saved compared with the traditional external supporting mode, and the adaptability to the measurement environment with limited external space is stronger;
16. In the invention, the centers of the pushing rod, the second hollow cylinder and the pipeline are arranged in a front-to-back collinear way, the graduated scale is arranged in bilateral symmetry relative to the central line, and the two groups of cursors are arranged in bilateral symmetry relative to the graduated scale, so that the integral measuring device can be arranged in a central symmetry way relative to the pipeline when the pipeline performs measurement operation, and the accuracy of the reference points for measuring the sizes of the pipeline is ensured;
