[0007] The flaw detection component includes a top channel-shaped frame, which is fixedly connected to the bottom end of the top support frame. A second servo reduction motor is installed on the right side of the top channel-shaped frame. Between the two sides inside the top channel-shaped frame, there is a laterally movably connected external thread driving rod. In front of and behind the external thread driving rod, there are respectively sliding rods. The external thread driving rod and the sliding rods are externally sleeved with internally threaded sliding blocks. On the left side of the bottom of the internally threaded sliding block, an ultrasonic flaw detection probe is fixedly connected. On the right side of the bottom of the internally threaded sliding block, a magnetic flux leakage flaw detection probe is fixedly connected.

[0008] Preferably, the left and right sides of the sliding rod are fixedly connected to the left and right sides inside the top trough-shaped frame respectively, and the output end of the second servo reduction motor is connected to the right side of the externally threaded driving rod.
