[0014] 1. The connecting assembly allows the connecting motor to drive the connecting gear to rotate. Because the connecting gear meshes with the moving tooth groove, the connecting sleeve block on the connecting motor moves in the direction of the mounting bracket. Then, the two connecting sleeve blocks move closer together, simultaneously driving the connecting shaft and the second sleeve block on the connecting recess to move. The second sleeve block then drives the connecting support plate to move. The assembly assembly allows the connecting support plate to drive the moving shaft and the moving recess on the first sleeve block to move. The moving support block on the moving recess pushes the mounting horizontal plate downwards. The mounting horizontal plate then drives the mounting push rod to align the second assembly arc piece with its corresponding first assembly arc piece. The first assembly roller on the first assembly arc piece and the second assembly roller on the second assembly arc piece then fully contact each other. The machining assembly allows the movable cylinder to push the machining milling head on the machining motor downwards, causing the milling head to move in the opposite direction to the rotating material, thus milling grooves into the material. This allows for clamping different specifications of materials as needed, and for clamping and fixing different specifications of drive shaft materials as needed, thereby improving the performance.

[0015] 2. The movable component allows the movable motor to drive the movable screw to rotate, and the movable slider moves along the direction of the movable screw. At the same time, the movable slider is slidably installed and guided inside the movable slot. Then, the movable slider also drives the movable support plate to move, and the movable support plate also drives the milling head on the processing component to adjust left and right to a suitable distance. At the same time, the mounting motor drives the mounting transmission wheel to rotate, and the mounting transmission wheel also comes into contact with the material. The friction between the mounting transmission wheel and the material causes the material between the first and second assembly arc parts to rotate centrifugally. Attached Figure Description

[0028] Working principle: In use, the material is first passed through multiple transmission rollers 2 between one of the first assembly arc parts 4 and one of the second assembly arc parts 8. Then, the connecting motor 24 is started, which drives the connecting gear 25 to rotate. Because the connecting gear 25 meshes with the moving tooth groove 18, it drives the connecting sleeve block 19 on the connecting motor 24 to move in the direction of the assembly bracket 3. Then, the two connecting sleeve blocks 19 move closer to each other. At the same time, the connecting sleeve blocks 19 also drive the connecting shaft 21 and the second sleeve block 22 on the connecting recess 20 to move. Then, the second sleeve block 22 also drives the connecting support plate 23 to move. This causes the connecting support plate 23 to drive the moving shaft 16 and the moving recess 15 on the first sleeve block 17 to move. Then, the moving support block 14 on the moving recess 15 pushes the mounting cross plate 9 to move downward.

[0029] Following the installation of the horizontal plate 9, the assembly push rod 7 pushes the second assembly arc piece 8 to align with its corresponding first assembly arc piece 4. Then, the first assembly roller 5 on the first assembly arc piece 4 and the second assembly roller 10 on the second assembly arc piece 8 come into full contact, thereby pressing materials of different specifications together as needed. Then, the installation motor 12 on the installation housing 11 is started, and the installation transmission wheel 13 is driven to rotate by the installation motor 12. At the same time, the installation transmission wheel 13 also comes into contact with the material, so that the friction between the installation transmission wheel 13 and the material causes the material between the first assembly arc piece 4 and the second assembly arc piece 8 to rotate centrifugally.

[0030] Simultaneously, the movable electric telescopic rod 26 is activated, which pushes the movable bracket 27 to move back and forth to a suitable distance. Then, the movable bracket 27 also drives the processing component on the movable support plate 30 to move, so that the processing component also drives the milling head 35 to adjust to a suitable distance.

[0031] Then, the movable motor 31 is started, which drives the movable screw 32 to rotate. The movable slider 28 moves along the direction of the movable screw 32. At the same time, the movable slider 28 is slidably installed and guided inside the movable groove. Then, the movable slider 28 also drives the movable support plate 30 to move. Then, the movable support plate 30 also drives the milling head 35 on the processing assembly to adjust left and right to a suitable distance. Then, the movable cylinder 33 is started, which pushes the milling head 35 on the processing motor 34 to move downward, so that the milling head 35 moves in the opposite direction to the rotating material, thereby milling grooves in the material.
