Step 4: Rotating the threaded rod (73) can drive the slider (74) to move at the lower end of the fixed plate (72), and at the same time, the pressure block (75) drives the clamping piece (76) to slide on the outside of the top shaft (6) to restrict the grey cloth and prevent the grey cloth from deflecting. When the grey cloth is rolled up, the top shaft (6) will be driven to rotate, and the top shaft (6) will drive the rotating ring (720) to rotate, thereby driving the push rod (722) to swing, so that the connecting handle (717) drives the blade (718) to move up and down to cut the side of the grey cloth. At the same time, the connecting handle (717) will drive the connecting ring (716) to make the rotating ring (715) rotate on the inside of the slide groove (714); Step 5: The two sides of the grey cloth can be pressed by the pressing wheel (711) to facilitate cutting by the blade (718). The pressing wheel (711) can be moved by the swing rod (710). The spring sheet (713) can drive the rotating shaft (712) to rotate to facilitate the pressing wheel (711) to return to its original position.
