The ball head 812 and linear bearing 804 drive the lifting shaft 805 to move. The lifting shaft 805 drives the magnet fixing seat 810 and the bar magnet 811 to move along the guide direction of the linear bearing 804 to adjust the distance between the bar magnet 811 and the track beam, thereby adjusting the magnetic attraction force of the flaw detection vehicle on the track beam, so that the flaw detection vehicle is stably attached to the track beam.
