[0026] Specifically, such as Figure 1 and Figure 2As shown, the adjusting shaft 9 can be turned according to the diameter of the annular inlet, which can drive the movable seat 11 to move downward. When the welding head 15 is adjusted to the welding position, it stops. The drive motor 4 is turned on to drive the fixed seat 6 to rotate. At this time, the connecting block 7 on one side of the fixed seat 6 can be guided to rotate in the annular groove 5, which facilitates precise welding of the annular inlet.

[0027] A welding head 15 is fixedly installed at the bottom of the movable base 11, and a connecting pipe 16 is fixedly connected to the right side of the welding head 15.

[0028] The front end of the movable seat 11 is fixedly connected to the storage seat 17. The storage seat 17 has four corners at the top and four corners with reserved slots 18.
