The upper end of the detection ring 19 is fixed to the driving shaft 5 through the second linkage frame 22.

[0037] The lifting rod 25 is rotatably installed through the second rotating groove 18 and the linkage ring 31, so that the lifting rod 25 is adapted to the rotation of the detection ring 19, so that the flaw detection component 4 is used to drive the driving shaft 5 to rotate, and the driving shaft 5 pulls the detection ring 19 and the linkage ring 31 to rotate synchronously, so as to realize the position switching of the ultrasonic detection device 6 and the image acquisition device 7, and the lifting rod 25 is used to realize the descent of the ultrasonic detection device 6 and the image acquisition device 7, so as to facilitate the adaptation with the detection cavity 24.

[0043] The push rod 10 drives the flaw detection component 4 and the detection block 3 to move longitudinally, and the material plate 2 is detected by using the ultrasonic detection device 6. When abnormal data is detected, the push rod 10 stops, and the flaw detection component 4 drives the detection ring 19 to rotate, so as to realize the position switching of the ultrasonic detection device 6 and the image acquisition device 7, and then the lifting rod 25 is used to adjust the focal length, and the image of the abnormal data position of the material plate 2 is collected to facilitate subsequent analysis;

[0044] When the flaw detection component 4 moves to the end of the outer guide rail 16, the single longitudinal movement is completed.
