[0003] After searching, the existing patent (application number: 202122220232.6) discloses a non-destructive testing device for the quality of pressure pipeline interfaces, including force bars that are cross-hinged and arranged with each other, and a wireless pressure sensor for detecting the pressure pipeline nozzle is symmetrically arranged at one end of the force bar, and a through hole is opened at the other end of the force bar, and a connecting column is inserted in the through hole. The force bar near one end of the connecting column is slidably connected with the force column, and a sleeve is provided outside the force column. A rotating rod is rotatably connected to the sleeve, and the free end of the rotating rod passes through the connecting column and is fixed with a turntable. The rotating rod and the connecting column are threadedly connected. The utility model effectively solves the problem that the traditional pressure pipeline detection device cannot detect pressure pipelines of different calibers, resulting in low detection efficiency. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] This type of detection device has poor functionality. It uses cross-hinged force bars and multiple connecting parts, making the overall structure relatively complex, which increases the manufacturing cost and maintenance difficulty, and may also affect the stability and reliability of the equipment. When using the device, it is necessary to adjust the position and angle of the force bar by rotating the turntable and the force column to adapt to pipes of different diameters. This operation is relatively cumbersome and may require certain skills and experience, which is not conducive to rapid and efficient detection;
