[0031] A placing plate 6 is installed on the upper side of the bottom plate 1;

[0032] An adjusting component is installed on the base plate 1 and is used to fix and clamp metal rods of different lengths;

[0033] The rotating assembly is installed on the front end of the adjusting assembly. The rotating assembly is used to rotate the metal rod. The device fixes the metal rod by limiting the adjusting assembly, and then drives the metal rod fixed in the adjusting assembly to rotate through the rotating assembly, so that the cutting tool 3 can cut the metal rod in a circular shape.

[0034] Furthermore, the adjustment component includes a slide groove 7, which is opened in the placement plate 6, and an opposing screw 8 is rotatably installed in the slide groove 7. Two groups of clamps 9 are movably installed in the slide groove 7, and the lower ends of the two groups of clamps 9 are sleeved on the opposing screw 8. First screws 10 are inserted at both ends of the two groups of clamps 9. First clamps 11 are symmetrically installed in the two groups of clamps 9. Four groups of first clamps 11 are rotatably connected to the four groups of first screws 10. This structure inserts a metal rod into the two groups of clamps 9, and then rotates the four groups of first screws 10 to drive the four groups of first clamps 11 to fit on the metal rod, so that the metal rod can be limited and fixed, and the two groups of clamps 9 can be driven to move closer or farther synchronously by rotating the opposing screw 8.

[0035] Furthermore, multiple groups of rotating rollers 12 are rotatably installed on the inner walls of the four groups of first clamps 11, and the outer walls of the multiple groups of rotating rollers 12 protrude from the inner walls of the first clamps 11. This structure, based on the rotating rollers 12 installed on the four groups of first clamps 11, makes it easy for the four groups of first clamps 11 to rotate the metal rod after being attached to the metal rod.

[0036] Furthermore, a gear ring 13 is rotatably mounted on the clamp 9 on the front side of the slide groove 7, and lifting rods 14 are fixedly mounted on both upper and lower ends of the gear ring 13. Second clamping plates 15 are fixedly mounted on two sets of lifting rods 14, and the two sets of second clamping plates 15 are symmetrically arranged. Under the action of the two sets of lifting rods 14, this structure drives the two sets of second clamping plates 15 to fit on the metal rod, so that the metal rod can be clamped and fixed in the gear ring 13.

[0037] Furthermore, the rotating assembly includes a gear 16, which is rotatably installed in the upper end of the clamp 9 on the front side of the slide 7. The gear 16 is meshed with the outer wall of the gear ring 13. A slot 17 is provided in the upper end of the clamp 9 in the front end of the slide 7 and the gear 16. A rotating rod 18 is inserted in the slot 17. Four groups of blocks 19 are arranged in a ring at the rear end of the rotating rod 18. When the metal rod is inserted in the two groups of clamps 9, the metal is inserted in the gear ring 13. The gear 16 is driven to rotate by rotating the opposing screw 8. The rotation of the gear 16 drives the gear ring 13 to rotate, thereby rotating the metal rod.

[0038] Furthermore, the inner wall of the slot 17 is adapted to the rear end of the rotating rod 18 and the four groups of blocks 19. This structure is adapted to the inner wall of the slot 17 according to the rear end of the rotating rod 18 and the four groups of blocks 19, so that when the rear end of the rotating rod 18 and the four groups of blocks 19 are inserted into the slot 17 on the gear 16, the rotating rod 18 can drive the gear 16 to rotate.

[0039] Working principle: When fixing the metal rod, Figure 2 , Figure 3 and Figure 4 As shown, first insert the metal rod into the two groups of clamps 9 and the gear ring 13, and according to the length of the metal rod, rotate the opposing screw rods 8 to drive the two groups of clamps 9 to slide closer or farther in the slide groove 7, and then rotate the four groups of first screw rods 10, the four groups of first screw rods 10 drive the four groups of first clamping plates 11 to fit on the metal rod, and under the telescopic action of the two groups of lifting and retracting rods 14, drive the two groups of second clamping plates 15 to fit on the metal rod, so that the front end of the metal rod can be fixed in the gear ring 13, pull the rotating rod 18 to drive the four groups of card blocks 19 to enter the card groove 17 on the gear 16, and then rotate the rotating rod 18 to drive the gear 16 to rotate, the rotation of the gear 16 drives the gear ring 13 to rotate, and the rotation of the gear ring 13 drives the metal rod to rotate. One end of the metal rod inserted in the two sets of clamps 9 rotates on the rotating roller 12 on the inner wall of the four sets of first clamps 11, so that the cutting tool 3 makes a circular cut on the metal rod. When cutting the metal plate, the rotating opposite screw rods 8 drive the two sets of clamps 9 to slide in the slide groove 7 to the front and rear ends of the slide groove 7, and the metal plate can be placed on the placement plate 6 for cutting.
