The oblique moving block 24 drives the limit connecting rod 25 to synchronously move in the moving process, and the limit connecting rod 25 drives the movable sleeve 251 to slide in the sleeve chute 26, if the oblique moving block 24 is closer to the positioning frame 21 after moving, the distance between the limit connecting rod 25 and the positioning frame 21 is shortened, the side length of a positive rectangle formed by the limit connecting rod 25 and the positioning frame 21 is synchronously reduced, so that the length of the positive rectangle is changed, and the cut length, namely the size of the cut positive rectangle is reduced;
The oblique moving block 24 is connected with the two-end movable blocks 31 through the expansion connecting column 27, and when the oblique moving block 24 moves obliquely, the two-end movable blocks 31 are driven to move obliquely, and because the distance between the oblique moving blocks 24 is changed, the two-end movable blocks 31 are stretched or extruded simultaneously, and the bending position is determined by the positions of the two-end movable blocks 31, so that the size of the required bending is adjusted by adjusting the positions of the oblique moving blocks 24.
