Rotating around the driven rotating rod 202 as the axis, the adjustment frame 205 rotates, causing the ultrasonic probe body 210 on the bottom surface of the adjustment rod 209 to rotate, thereby adjusting its detection direction. During the detection process, the active screw 302 is driven to rotate, which in turn causes the limiting protective box 211 on the surface of the connecting slide plate 301 to move horizontally inside the detection box body 1. The movement of the limiting protective box 211 causes the ultrasonic probe body 210 below to move horizontally simultaneously inside the detection box body 1, thereby enabling the simultaneous detection of multiple valve bodies in the detection box body 1. This effectively shortens the detection time and allows the device to freely perform flaw detection on multiple sides of the valve body by adjusting the ultrasonic probe body 210 in multiple directions and angles. This effectively avoids the need for time-consuming and laborious handling of the valve body during multi-sided valve body detection, greatly saving manpower and further improving the detection efficiency of the device.
