Then, through the meshing action between the teeth 26 of the second slider 19 and the teeth of the toothed plate 17, drive the second slider 19 to move leftward. The first U-shaped frame 21 fixedly connected to the second slider 19 will move leftward. The vertical plate 7, the second U-shaped frame 27 and the first U-shaped frame 21 form a whole and will move leftward together, moving the straightening machine 3 above the second U-shaped frame 27 to the left.

[0030] When it is necessary to move the straightening machine 3 to the right, start the power supply. The runner 15 and the gear 18 rotate counterclockwise, driving the toothed plate 17 to move rightward. Then, through the meshing action between the teeth 26 of the second slider 19 and the teeth of the toothed plate 17, drive the second slider 19, the first U-shaped frame 21, the vertical plate 7 and the second U-shaped frame 27 to move rightward as a whole, so as to move the straightening machine 3 to the right.
