[0031] The specific usage and function of this embodiment are as follows:

[0032] In this utility model, when... Figure 1 As shown, when using the device body 1, the supporting cylindrical rod 9 is fixed to the external testing platform via a threaded post. The right end wire of the ultrasonic probe 4 is connected to the external control device. The pressure vessel is placed on the external testing platform, and the left end of the ultrasonic probe 4 is aligned with and pressed against the pressure vessel. Then, ultrasonic testing is performed on the pressure vessel. When the height of the ultrasonic probe 4 is adjusted, the lifting adjustment cylinder 8 is rotated using a tool to engage with the threaded lifting rod 2, causing the lifting rod 2 to rise through the threaded engagement. The lifting rod 2 drives the bearing tilting plate 3 to rise synchronously, and the bearing tilting plate 3 carries the ultrasonic probe 4 to rise synchronously, as shown in the diagram. Figure 6 As shown, this achieves height adjustment of the ultrasonic probe 4. When the angle of the ultrasonic probe 4 is adjusted, the angle adjustment cylinder 5 is engaged with the threaded lifting rod 2 by rotating the tool, causing the angle adjustment cylinder 5 to descend through the threaded engagement. The angle adjustment cylinder 5 then drives the angle support cylinder 6 to descend synchronously via the bearing. The angle support cylinder 6 then drives the lower end of the angle support rod 7 to descend synchronously. The upper end of the angle support rod 7 then drives the left end of the load-bearing flip plate 3 to flip downwards. The load-bearing flip plate 3 carries the ultrasonic probe 4 and flips downwards synchronously, as shown in the diagram. Figure 4 As shown, this achieves angle adjustment of the ultrasonic probe 4. When the angle adjustment cylinder 5 rises through threaded engagement, the state is as follows. Figure 5 As shown, this enables the ultrasonic probe 4 to perform multi-angle inspections of the pressure vessel.

[0033] Example 2: The difference from Example 1 is that the regular hexagonal prism of the fixed anti-rotation column 10 can also be set as a regular heptagonal prism, so that the fixed anti-rotation column 10 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the fixed anti-rotation column 10.

[0034] Example 3: The difference from Example 1 is that the regular hexagonal structure of the lifting adjustment cylinder 8 can also be set as a regular heptagonal structure. This makes the lifting adjustment cylinder 8 require a special tool that works with the regular heptagonal structure to rotate, thus preventing non-staff members from rotating and adjusting the lifting adjustment cylinder 8.
