One end of the positive and negative screw rod 9 penetrates through the positioning plate 8 and is connected to a swivel ring 14.

[0022] When working, the square frame 1 drives the fixed rods 4 and the V-shaped limiting blocks 5 to move through the sliding bearings 3 at the four corners of the rectangular chute 2. After adjusting the V-shaped limiting blocks 5 to the positions of the four corners of the paper box, the threaded bolts 7 are rotated to tightly press against the sidewall of the rectangular chute 2 to realize fixation.

[0025] Further, the axis of the threaded hole 6 is perpendicular to the extension direction of the rectangular slide groove 2, and the end of the threaded bolt 7 is provided with an anti-skid rubber pad in contact with the inner wall of the rectangular slide groove 2.

[0026] In operation, the axis of the threaded hole 6 is perpendicular to the extension direction of the rectangular slide groove 2, and when the threaded bolt 7 is rotated, the end of the anti-skid rubber pad is in frictional contact with the inner wall of the rectangular slide groove 2, thereby increasing the locking resistance. The threaded bolt 7 in the vertical locking direction is combined with the anti-skid rubber pad, thereby enhancing the anti-vibration loosening capability of the V-shaped limiting block 5 and ensuring the stability during cutting.

[0027] Further, the limiting rod 12 is parallel to the positive and negative threaded rod 9, the inner wall of the sliding hole 13 is in clearance fit with the limiting rod 12, and the vertical section of the AL-shaped plate 10 and the BL-shaped plate 11 is lower than the top plane of the square frame 1.
