[0025] In this embodiment, a fixed groove 11 is provided on the fixed seat 1, and a movable seat 12 is movably installed inside the fixed groove 11. A third power mechanism 22 is fixedly installed on the movable seat 12. The third power mechanism 22 is a DC motor, which drives the winding drum 13 to rotate. The winding drum 13 is installed on the third power mechanism 22. A slide groove 21 is provided on one side of the fixed seat 1, and a connecting groove 23 is provided on the fixed seat 1. A slider 25 is movably installed inside the connecting groove 23 and the slide groove 21. The slider 25 is installed inside the slide groove 21 through a supporting mechanism 26. A limiting seat 24 is welded on the side of the slider 25. Limiting grooves are provided inside the slide groove 21 and the connecting groove 23. A limiting block 27 is fixed on the slider 25, and the limiting block 27 is movably installed inside the limiting groove. The supporting mechanism 26 is a supporting spring, and the supporting spring pushes the slider 25 into the inside of the connecting groove 23 to limit and fix the movable seat 12.

[0026] In this embodiment, the limit assembly 9 includes a movable rod 15, a threaded hole is formed on the movable rod 15, and the movable rod 15 is installed on the threaded column 8 through the threaded hole. A limit ring 16 is welded to one end of the movable rod 15, and the limit ring 16 is mounted on the rotating column 5. A bearing is rotatably mounted on one side of the limit ring 16, and the bearing is in contact with the side of the fixed ring 17. A block 20 is welded on the inner wall of the fixed ring 17, and a slot 19 is formed on the rotating column 5. The block 20 is movably mounted inside the slot 19. The limit ring 16 is in contact with the fixed ring 17 through the bearing, thereby reducing the friction force of the fixed ring 17 on the limit ring 16.

[0027] The device provides the required electric energy for the electrical appliances inside the device through an external power supply. When using the device, first install the unwinding drum and the winding drum 13 inside the fixed groove 11 through the movable seat 12.

After the limit and fixation, the paper passes through the support roller 10, the driven roller 7 and the active roller 6. Later, the active roller 6 provides assistance for the movement of the paper. When it is necessary to adjust the distance between the blades 18, the handle is turned. 14 drives the threaded column 8 to rotate, and the threaded column 8 drives the movable rod 15 to move horizontally. The movable rod 15 pushes the fixed ring 17 to move on the rotating column 5 through the limiting ring 16, and the clamping block 20 slides horizontally inside the clamping groove 19. After sliding, the limiting ring 16 limits and fixes the fixed ring 17 from both sides of the fixed ring 17, thereby starting the first power mechanism 3 to drive the rotating column 5 to rotate. The rotating column 5 drives the blade 18 to rotate and cut through the clamping groove 19 and the clamping block 20. The blade 18 is later moved to the side of the paper through the fixing ring 17, and the curved edges on both sides of the paper can be cut. At the same time, the blades 18 cooperate with each other to complete the simultaneous cutting of papers of different widths.
