[0029] Working principle: the user places the metal rod 5 to be cut on the first clamping seat 3 and the second clamping seat 4 in advance. At this time, the two groups of blocks 13 are respectively at the two ends of the strip groove 8. At this time, the user rotates the left extrusion bolt 17. At this time, the extrusion bolt 17 rotates and moves upward in the square nut until the extrusion bolt 17 is out of contact with the support frame 7, and the lock on the left block 13 is released. At this time, the user moves the block 13 in the left position to the right until the block 13 is moved to a suitable position according to the length of the metal rod 5, and the extrusion bolt 17 is re-contacted with the support frame 7 to position the block 13. Then the user turns on the second cylinder 15 through the controller. At this time, the second cylinder 15 can drive the pressure plate 19, the pressure block 21 and the pressure plate 19 The other connecting parts on the upper part move downward together until the bottom of the pressure block 21 contacts the top of the metal rod 5, and the top of the metal rod 5 is pre-positioned, and before the pressure block 21 contacts the metal rod 5, the elastic sealing ring 34 at the bottom of the vacuum suction cup 33 will contact the bottom frame 1 in advance, and as the pressure block 21 and the metal rod 5 approach, the support plate 31 will move up and down in the U-shaped pipe 32, causing the spring 37 to deform. At this time, the elastic rebound of the spring 37 can make the vacuum suction cup 33 contact the bottom frame 1 more closely, and at this time, the controller controls the second motor 29 to turn on. At this time, the second motor 29 can drive the two sets of screw rods 22 to rotate synchronously with the cooperation of the pulley 30.

At this time, the air pump 46 can extract the gas in the vacuum suction cup 33 through the U-shaped pipe 32, the first telescopic hose 40 and the three-way pipe 42 until the vacuum suction cup 33 is evacuated into a vacuum state, so that the vacuum suction cup 33 can be quickly adsorbed on the bottom frame 1, thereby stably supporting the auxiliary frame 24. Then the user turns off the air pump 46 and the fourth solenoid valve through the controller, and turns on the third cylinder 25. At this time, the third cylinder 25 can drive the U-shaped frame 26 and the limit plate 27 to move inward synchronously, and the front and The back side is squeezed and positioned. At this time, the three sides of the metal rod 5 in different directions can be fixed synchronously with the pressure block 21. Then the user turns on the air pump 46 and the third solenoid valve through the controller. At this time, the air pump 46 can quickly extract the gas in the chamber 43 through the docking elbow 44, the second telescopic hose 45 and the three-way pipe 42, so that the chamber 43 remains in a vacuum state, so that the bottom of the metal rod 5 can be quickly adsorbed with the cooperation of the adsorption hole, and the elastic sealing pad 49 can ensure the sealing effect, so that the metal rod 5 can be quickly fixed in different directions, and the fixing methods used are diversified, which further improves the fixing effect of the metal rod 5 and can effectively avoid the displacement of the metal rod 5. Then the user turns on the first cylinder 9 and the first motor 11 through the controller.At this time, the first motor 11 can drive the cutting disc 12 to rotate, and the first cylinder 9 controls the height of the mounting frame 10 and the cutting disc 12, so that the metal rod 5 can be stably cut.
