[0037] In this embodiment: Connect the motor 508 to power and run it, so that the output shaft of the running motor 508 drives the gear 509 to rotate forward. Since both racks 5010 are engaged with the gear 509, the forward-rotating gear 509 drives the two racks 5010 to move closer to each other. The two racks 5010 in the moving-closer state respectively drive the two sliders 502 to move along the trajectories of the two chutes 501.

[0046] The electric push rod 505 is fixedly connected to the top of the machine base 1. The sleeve 506 is fixedly connected to the output end of the electric push rod 505. The receiving groove 5014 is opened inside the sleeve 506. The spring 5015 is fixedly installed inside the receiving groove 5014. The connecting rod 5011 is slidably connected inside the receiving groove 5014, and one end of the connecting rod 5011 is fixedly connected to the end of the spring 5015. The locking block 5012 is rotatably connected to the other end of the connecting rod 5011. The locking hole 5013 is opened on the surface of the protruding part of the second support plate 504.

[0047] In this embodiment: Move the connecting rod 5011 to the outside of the receiving groove 5014, so that the connecting rod 5011 in the outward moving state stretches the spring 5015, and the connecting rod 5011 in the outward moving state drives the horizontally straight locking block 5012 to insert into the locking hole 5013. Then, rotate the horizontally straight locking block 5012 to the vertical state, so that the rotated vertical locking block 5012 is engaged with the locking hole 5013. Then, dock the connecting rod 5011 with the second support plate 504. As described above, dock the two connecting rods 5011 with the two second support plates 504 respectively. Then, connect the electric push rod 505 to power and run it. The output end of the running electric push rod 505 drives the sleeve 506 to move upward. The upward moving sleeve 506 drives the two connecting rods 5011 to move upward. The two upward moving connecting rods 5011 drive the two second support plates 504 to move upward respectively.

[0050] Working principle: First, place the multi-layer corrugated paper to be cut at the center of the cutting table 2. At this time, connect the motor 508 to the power supply and run it, so that the output shaft of the running motor 508 drives the gear 509 to rotate forward. Since both racks 5010 are engaged with the gear 509, the forward-rotating gear 509 drives the two racks 5010 to move closer to each other. The two racks 5010 in the state of moving closer to each other drive the two sliders 502 to move along the tracks of the two chutes 501 respectively. The two sliders 502 in the state of moving closer to each other drive the two first support plates 503 and the second support plate 504 to move respectively. Then the two first support plates 503 and the second support plate 504 in the state of moving closer to each other support and limit both sides of the multi-layer corrugated paper to be cut, and the distance between the two first support plates 503 can be adjusted according to the size of the multi-layer corrugated paper to be cut, so that this structure is adapted to corrugated paper of different sizes;

[0051] At this time, move the connecting rod 5011 to the outside of the receiving groove 5014, so that the connecting rod 5011 in the state of moving outward stretches the spring 5015, and the connecting rod 5011 in the state of moving outward drives the lock block 5012 in the horizontal and vertical states to be inserted into the interior of the keyhole 5013, and then the lock block 5012 in the horizontal and vertical states is rotated to the vertical state, so that the lock block 5012 rotated to the vertical state engages with the keyhole 5013, and then the connecting rod 5011 is docked with the second support plate 504. As described above, the two connecting rods 5011 are respectively docked with the two second support plates 504, and then the electric push rod 505 is connected to the power supply and run, so that the output end of the running electric push rod 505 drives the sleeve 506 to move upward. The upward-moving sleeve 506 drives the two connecting rods 5011 to move upward. The two upward-moving connecting rods 5011 drive the two second support plates 504 to move upward respectively. The upward-moving second support plate 504 adjusts the overall height of the second support plate 504 and the first support plate 503. Thus, the first support plate 503 and the upward-moving second support plate 504 cooperate to support and limit multi-layer corrugated paper of different heights.
