[0027] A cylinder 11 is fixedly mounted on the upper end of the base 6, and a telescopic end of the cylinder 11 is fixedly connected to one of the first supporting plates 2;

[0031] Working principle:

[0032] When in use, the driving motor 13 drives the second double-headed screw 7 to rotate through the second synchronous pulley set 14, so that the second nut 12 and the second supporting plate 3 above move, and the second supporting plates 3 at both ends move relatively to achieve the centering of the material in the length direction;

[0033] The cylinder 11 pushes the first supporting plate 2, and the movement of the first supporting plate 2 causes the first nut 10 connected below to move.
