The driving motor 28 drives the lead screw 26 to rotate. The lead screw 26 drives the moving rod 24 to move through the lead screw nut 27 and the sleeve plate 23. The moving rod 24 pushes the limiting plate 19 to move towards the adjusting disc 7. At the same time, the rotating motor 29 drives the second gear 30 to rotate through the first gear 31. The second gear 30 drives the limiting plate 19 to rotate a certain angle. Then the staff controls the rotation of the adjusting disc 7 so that the rotating arm 6 rotates until it is in close contact with the limiting plate 19. At this time, the roller 9 contacts the side surface of the angle steel. The roller 9 does not affect the movement of the angle steel and supports the angle steel from the side to prevent the angle steel from tilting and protect the safety of the staff. After use, the staff manually controls the rotation of the adjusting disc 7 to drive the roller 9 and the rotating arm 6 to rotate around the adjusting disc 7 as the center, so that the roller 9 rotates to the side of the side plate 2 to realize the retraction of the roller 9. And by rotating the locking screw 8, the adjusting disc 7 is controlled to be tightened to realize the locking of the adjusting disc 7 and prevent the roller 9 and the rotating arm 6 from occupying space.
