[0027] The short roller 3 is synchronously unfolded with the circular arc connecting shaft to form a symmetrical curvature circular arc; the anti-skid sleeve 4 is automatically unfolded and tightened when the interval increases, the length of the anti-skid sleeve 4 is designed to be 1.3 times of the minimum interval of adjacent short rollers 3, so as to ensure that it is always close to the coiled material.

[0028] The elongated end of the telescopic rod 8 is inclined towards the outside of the vehicle frame body 1 away from the vehicle frame body 1 and towards the rear side of the moving direction.

[0029] As shown in Figure 2 and Figure 5 , the first connecting shaft 6 and the second connecting shaft 7 are circular arc-shaped and have the same curvature, and the elongated end of the telescopic rod 8 is inclined towards the outer rear side of the vehicle frame body 1.
