A connecting rod 10 is fixedly connected to the flat plate mounting mechanism, and the connecting rod 10 is movably connected to the cage 6.

[0025] During use, the groove on the claw 1 fits with the pipeline 3 to be detected, and then the hook 2 is hooked onto the pipeline 3 to be detected. The threaded rod 4 fixedly connected to the hook 2 passes through the through hole on the claw 1. When the hand crank 5 is rotated to tighten the hand crank 5 and the threaded rod 4, the hand crank 5 fits tighter and tighter with the hook 2, so that the hook 2 firmly hooks the pipeline 3 to be detected, and the device is fixed on the pipeline 3 to be detected. The pipeline 3 to be detected is located between the ray machine and the flat panel detector 7. The bottom plate 9 is used to connect the cage 6. The cage 6 is movably arranged on the bottom plate 9, which is convenient for adjusting the position of the ray machine. The flat plate mounting mechanism and the cage 6 are movably connected through the connecting rod 10, which is convenient for adjusting the distance between the flat plate mounting mechanism and the cage 6, so as to facilitate the focusing of the ray machine and the flat panel detector 7.

[0026] Further optimized solution, the flat plate mounting mechanism includes a mounting plate 11. Two guide grooves 12 are fixedly connected to the mounting plate 11.
