[0032] Working principle: Move the device to a suitable position, start the second motor 73 to drive the threaded sleeve 71 to rotate inside the top box 7, so that the two threaded rods 72 retract inward and pull the two sliding blocks 6 closer to each other, and squeeze the drive box 2 by the extrusion rod 61 to push the drive box 2 down to adjust the installation height value of the first cutting blade 31 and the second cutting blade 41. Then, start the first motor 5 to drive the connecting bevel gear 51 to rotate, and under the action of the second bevel gear 42 and the first bevel gear 32, the first cutting blade 31 and the second cutting blade 41 are driven to rotate and the rotation directions are opposite.
