[0018] Step 3: Enhance cleaning effect;

[0019] Step 4: Improve rotational stability.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the workpiece sleeve is placed on the top outer wall of the special-shaped frame, and the first electric telescopic rod is started. The first electric telescopic rod drives the square plate to descend, and the square plate drives the forward and reverse motors to descend. The forward and reverse motors drive the rotating shaft to descend, and the rotating shaft drives the cross sleeve to descend. When the cross sleeve moves to the inside of the cross groove of the inner wall of the special-shaped frame, the forward and reverse motors are started. The forward and reverse motors drive the rotating shaft to rotate, and the rotating shaft drives the cross sleeve to rotate. The cross sleeve drives the special-shaped frame to rotate, and the special-shaped frame drives the workpiece sleeve to rotate. At the same time, the second electric telescopic rod is started. The second electric telescopic rod drives the cutter to move upward at a uniform speed. During the upward movement of the cutter, it will contact the side wall of the workpiece sleeve. Contact occurs, thereby performing thread cutting on the outer wall of the workpiece sleeve. When the special-shaped shell frame rotates, the special-shaped shell frame drives the screw rod to rotate. Limited by the working shell, the screw rod drives the threaded plate to vertically descend, and the threaded plate drives the rotating plate to descend. Limited by the square hole, the rotating plate drives the slider to slide along the inner wall of the square hole, the slider drives the square shell to move, the square shell drives the slide plate to move, the slide plate drives the cross bar to move, and the cross bar drives the arc-shaped clamping plate to move. The two arc-shaped clamping plates approach each other, thereby clamping the outer wall of the bottom end of the special-shaped shell frame to prevent slight shaking during the rotation of the special-shaped shell frame, thereby improving the accuracy of thread cutting.

[0022] (2) According to the present invention, when the square shell moves, the square shell drives the vertical rod to move, the vertical rod drives the vertical plate to move, the vertical plate drives the sliding frame to move, the sliding frame drives the clamping shell to move, and the clamping shell drives the rotating belt to move. During the movement of the rotating belt, the rotating belt will come into contact with the outer wall of the rotating workpiece sleeve, thereby scraping and cleaning the iron filings generated during the thread cutting process to prevent the iron filings from affecting the integrity of the thread groove. Due to the setting of the rotating belt, the rotating belt is in a rotating process inside the clamping shell. When the rotating belt contacts the side wall of the rotating workpiece sleeve, the two rotating belts approaching each other are rotated inside the clamping shell by the rotational force applied by the workpiece sleeve, thereby preventing the rotating belt from affecting the thread cutting of the workpiece sleeve, thereby improving the thread cutting stability of the workpiece sleeve.

[0023] (3) According to the present invention, when the reaction force of the workpiece sleeve is applied, the rotating belt drives the clamping shell to move, the clamping shell approaches the vertical plate, the clamping shell drives the sliding frame to move, the sliding frame drives the rotating bar to move, and when the limiting hole is applied, the rotating bar drives the block to move along the inner wall of the limiting hole, the block drives the fixed shell to move, and the fixed shell drives the brush plate to move. When the two brush plates approach each other, they can contact the side wall of the workpiece sleeve, thereby cleaning the iron filings remaining in the thread groove of the workpiece sleeve, thereby improving the quality of the thread cutting of the workpiece sleeve.

[0024] (4) In the present invention, when the square shell moves toward the special-shaped shell frame, it is subjected to the reaction force of the special-shaped shell frame, and the arc-shaped clamping plate drives the cross bar to move toward the inside of the square shell, and the cross bar drives the slide plate to move. During the process of the slide plate squeezing the inside of the square shell, the liquid inside the square shell enters the inside of the first elastic tube, and the liquid enters the inside of the clamping shell through the first elastic tube, cooling the rotating belt inside the clamping shell to prevent the rotating belt from being worn during the long-term contact between the rotating belt and the workpiece sleeve. Because the interior of the clamping shell is in a closed setting, when the liquid fills the interior of the clamping shell, the liquid will enter the interior of the second elastic tube, and the liquid will enter the interior of the fixed shell through the second elastic tube, and be subjected to the reaction force of the fixed shell. The circular hole is opened, and the liquid enters the interior of the circular hole through the fixed shell, and the liquid is sprayed toward the outer wall of the rotating workpiece sleeve through the circular hole, further preventing debris from adhering to the thread groove of the workpiece sleeve. When the vertical plate moves, the vertical plate drives the connecting shell to move. Affected by the setting of the card slot at the bottom of the square plate, the two connecting shells approach each other along the card slot. When the connecting shell moves to the top of the workpiece sleeve, it is elastically deformed by the extrusion spring, and the extrusion spring presses the extrusion block downward. The extrusion block vertically descends along the outer wall of the limit rod, thereby slightly pressing down the top of the workpiece sleeve, making the workpiece sleeve and the bottom end of the special-shaped shell frame more tightly clamped, thereby improving the stability of the workpiece sleeve rotation and the stability of the workpiece sleeve thread cutting from the side.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The outer wall of the fixed shell 684 is connected to a second elastic tube 687.

The extrusion spring 6810 presses down the extrusion block 6811, and the extrusion block 6811 drops vertically along the outer wall of the limiting rod 689, thereby slightly pressing down the top of the workpiece sleeve 651, so that the workpiece sleeve 651 and the bottom end of the special-shaped frame 64 are more tightly clamped, thereby improving the rotation stability of the workpiece sleeve 651 and the side stability of the workpiece sleeve 651 in cutting threads.

Due to the setting of the rotating belt 675, the rotating belt 675 is in a rotating process inside the clamping shell 674. When the rotating belt 675 contacts the side wall of the rotating workpiece sleeve 651, the two rotating belts 675 approaching each other are rotated inside the clamping shell 674 by the rotational force applied by the workpiece sleeve 651, preventing the rotating belt 675 from affecting the thread cutting work of the workpiece sleeve 651, thereby improving the thread cutting stability of the workpiece sleeve 651.

[0056] When subjected to the reaction force of the workpiece sleeve 651, the rotating belt 675 drives the clamping shell 674 to move, and the clamping shell 674 approaches the vertical plate 672, and the clamping shell 674 drives the sliding frame 673 to move, and the sliding frame 673 drives the rotating bar 681 to move. Limited by the limiting hole 682, the rotating bar 681 drives the block 683 to move along the inner wall of the limiting hole 682, and the block 683 drives the fixed shell 684 to move, and the fixed shell 684 drives the brush plate 685 to move. When the two brush plates 685 approach each other, they can contact the side wall of the workpiece sleeve 651, thereby cleaning the iron filings remaining inside the thread groove of the workpiece sleeve 651, thereby improving the quality of thread cutting of the workpiece sleeve 651.

[0057] When the square shell 663 moves toward the special-shaped shell frame 64, it is subjected to the reaction force of the special-shaped shell frame 64, and the arc clamping plate 667 drives the cross bar 666 to move into the inside of the square shell 663, and the cross bar 666 drives the slide plate 664 to move. During the process of the slide plate 664 being squeezed inside the square shell 663, the liquid inside the square shell 663 enters into the inside of the first elastic tube 677, and the liquid enters into the inside of the clamping shell 674 through the first elastic tube 677, and the temperature of the rotating belt 675 inside the clamping shell 674 is cooled to prevent the rotating belt 675 from being worn during the long-term contact between the rotating belt 675 and the workpiece sleeve 651. Because the interior of the clamping shell 674 is in a closed setting, when the liquid fills the interior of the clamping shell 674, the liquid will enter into the inside of the second elastic tube 687, and the liquid will enter into the interior of the fixed shell 684 through the second elastic tube 687, and the rotating belt 675 inside the clamping shell 674 will be subjected to the reaction force of the special-shaped shell frame 651. The opening allows liquid to enter the interior of the circular hole 686 through the fixed shell 684, and the liquid is sprayed toward the outer wall of the rotating workpiece sleeve 651 through the circular hole 686, further preventing debris from adhering to the thread groove of the workpiece sleeve 651. When the vertical plate 672 moves, the vertical plate 672 drives the connecting shell 688 to move. Affected by the setting of the card slot 6813 at the bottom of the square plate 5, the two connecting shells 688 approach each other along the card slot 6813. When the connecting shell 688 moves to the top of the workpiece sleeve 651, it is elastically deformed by the extrusion spring 6810. The extrusion spring 6810 presses the extrusion block 6811 downward, and the extrusion block 6811 vertically descends along the outer wall of the limit rod 689, thereby slightly pressing down the top of the workpiece sleeve 651, so that the workpiece sleeve 651 and the bottom end of the special-shaped shell frame 64 are more tightly positioned, thereby improving the rotation stability of the workpiece sleeve 651 and the side stability of the workpiece sleeve 651 in cutting the thread.
