[0026] Reference Figure 3 , Figure 4 , Figure 5A support frame 17 is fixedly connected to the top of the base 1, and an auxiliary frame 18 is fixedly connected to the top of the base 1. A limiting push rod 19 is rotatably connected inside the support frame 17. The support frame 17 and the auxiliary frame 18 are located at both ends of the top of the base 1, providing additional support and stability. Each of them has a limiting push rod 19 inside, which is used to precisely control the connection between carbon steel pipes to prevent gaps and unsatisfactory welding results. Two rotating shafts 11 are rotatably connected inside the support frame 17. A transmission shaft 12 is fixedly connected to the outside of the left rotating shaft 11. The rotating shaft 11 is responsible for connecting the support frame 17 and the transmission shaft 12, and transmitting the rotational force brought by the transmission shaft 12 to the limiting shaft 9.

[0027] Two rotating shafts 11 are fixedly connected to adjacent sides of a limiting shaft 9, which drives the installed carbon steel pipe to rotate, thereby achieving one-time welding of the carbon steel pipe. A fixing screw 10 is detachably connected to the outside of the limiting shaft 9, facilitating changes to the model of the limiting shaft 9 and making the device operation more flexible. Two limiting push rods 19 are each fixedly connected to adjacent sides of a transmission shaft 22.

The top of the base 1 is provided with a sliding groove, and the sliding block 20 and the limiting block 21 are installed in the sliding groove. The bottom of the base 1 is fixedly connected to a support column 27 to further increase the support for the device.

[0028] Working principle: First, the carbon steel pipe is placed on the base 1. The sliding block 6 is adjusted to the appropriate position via the sliding frame 2 to ensure the pipe is fixed. Next, the rotating block 3 is rotated to a specific angle as needed to adapt to different pipe shapes. The fixing ring 7 should position the sliding block 6 and the rotating block 3 so that the fixing ring 7 fits the pipe and ensures that the movement of the pipe is restricted. The fixing buckle 25, which is rotated and connected to the outside of the fixing shaft 4, is turned to drive the locking teeth 26 to engage in the groove on the sliding frame 2. Subsequently, the limiting push rod 19 is precisely aligned with the pipe through the support frame 17 and the auxiliary frame 18. The limiting push rod 19 pushes the transmission shaft 22, and the transmission shaft 22... The power block 23 is pushed, and finally the power block 23 pushes the pipe fitting, ensuring that there are no gaps between the pipe fittings. The motor 15 starts, and the power is transmitted to the transmission shaft 12 through the power shaft 14 and the belt 13. The transmission shaft 12 transmits the rotational force to the limiting shaft 9 through the rotating shaft 21, thereby driving the limiting shaft 9 to rotate, thus completing the rotation of the pipe fitting, which facilitates welding and makes the welding process without dead angles. All pipe fittings can be welded at once. At the same time, the auxiliary frame 18 and the sliding block 20 adjust their positions according to the length of the pipe fitting, ensuring the stability and flexibility of the entire device. Finally, after the welding is completed, the user can quickly release the buckle assembly and take out the welded pipe fitting.
