[0033] As shown in Figure 1 and Figure 2 The number of the rotating rods 10 is two, and the two rotating rods 10 are symmetrically distributed along the outer wall of the moving plate 14; by setting the structure of the two rotating rods 10, the moving plate 14 can pull the two sides of the rotating plate 9 to synchronously rotate when moving, so as to ensure that the rotating plate 9 will not be positionally deviated during rotation, and further improve the stability of the rotating plate 9 during rotation.

[0034] The technical scheme provided by the utility model, when working, by loosening the first stud 28 and the second stud 30, so that the adjusting plate 24 and the positioning plate 17 and the limiting plate 12 are all in the state of active connection, it is convenient to pull the adjusting plate 24 to change the position of the fixing hole 25, then the fixing rod on the welding tool can be respectively passed through the slot 18 and the fixing hole 25, so that the welding tool is fixed on the rotating plate 9 by the threaded connection of the nut and the fixing rod, and when fixing different models of welding tools, the position of the fixing hole 25 is adjusted by the above-mentioned synchronous steps until the different models of welding tools can be installed on the rotating plate 9, and in the welding process, the angle between the first supporting arm 3, the second supporting arm 4 and the third supporting arm 5 can be changed by the operation of the first strong motor 2, so that the rotating plate 9 approaches the position where the workpiece needs to be welded, and the rotating plate 9 can also be changed in angle by the operation of the second strong motor 7 when welding.
