[0002] In the inspection of long-distance steel pipelines, TOFD is a commonly used inspection method. TOFD inspection technology is divided into parallel scanning, oblique scanning and non-parallel scanning. There are different scanners corresponding to the above-mentioned scanning methods. In the scanning, the scanner used to fix the probe is a key auxiliary device. However, when defects are found in the non-parallel scanning on site and the specific location needs to be determined, the parallel scanner must be replaced for lateral scanning. At present, there is a lack of a scanner that combines the above three scanning methods. When changing the scanning direction, it is necessary to manually change the scanning direction, which is time-consuming and labor-intensive.

[0003] How to solve the above technical problems is the subject faced by the present utility model. Utility Model Content
