Then, the staff starts the two drive motors according to the width of the cardboard. The two drive motors drive the screws to rotate respectively, thereby driving the two guide plates to approach each other through the screws. When the two guide plates are respectively in contact with the left and right sides of the cardboard, the staff stops the two drive motors, thereby fixing the cardboard horizontally between the two guide plates. By setting two movable guide plates to level the cardboard, the device can cut cardboards of different widths, thereby improving the applicability of the device. After fixing the cardboard horizontally, the staff can move the two fixed plates up and down according to the height of the cardboard. When the two fixed plates are respectively in contact with the top surface of the cardboard, the staff can connect the bolts through the fixing holes and the internal threads of the threaded grooves, so that the two fixed plates press the cardboard, thereby completely fixing the cardboard between the two guide plates. During the cardboard cutting process, the cardboard is subjected to the pressure of the two fixed plates and the friction between the cardboard and the cutting table. The cardboard will not deviate forward or backward, nor will it bend upward due to the resistance of the two guide plates, thus ensuring the accuracy of the cardboard cutting position and preventing cutting errors.

[0015] 2. During use, when the cardboard is completely fixed between the two guide plates, the staff can move the first electric telescopic rod on the slide rod until the first electric telescopic rod moves to the leftmost side of the moving groove. At this time, the staff selects cutters of different sizes according to the height of the cardboard, and then connects the threaded sleeve at the top of the cutter with the internal thread of the rotating groove at the bottom of the telescopic end of the second electric telescopic rod, thereby fixing the cutter to the bottom of the second electric telescopic rod, and then adjusts the height of the first electric telescopic rod so that the cutter is against the top surface of the cutting table. At this time, the staff adjusts the length of the second electric telescopic rod until the cutter is moved to the cutting position of the cardboard. When the position of the cutter is fixed, the staff moves the cutter to the right to cut off the unnecessary area of ​​the cardboard. By setting the first electric telescopic rod and the second electric telescopic rod, cutters of different sizes can be replaced, and the cutter can be moved to any area on the cutting table, which improves the applicability and convenience of the device.
