Inside the double-sided shearing machine 1, a conveying roller 2, a first shearing roller 3, and a second shearing roller 4 are arranged. At the surface of the outer end feeding port of the double-sided shearing machine 1, a support bracket 5 is fixed. On the inner surface of the support bracket 5, a first positioning roller 6 and a second positioning roller 7 are arranged. Inside the support bracket 5, a U-shaped frame 8 is arranged. On the inner surface of the U-shaped frame 8, a telescopic adjusting roller 9 is arranged. On the lower surface of the U-shaped frame 8, a threaded rod 10 is fixed. Inside the inner surface of the support bracket 5, a T-shaped cylinder 11 is inserted and arranged;
