[0035] like Figure 2As shown, the first positioning mechanism 2 includes a support frame 21, a first positioning rod 22 and a first positioning block 23. A plurality of support frames 21 and first positioning rods 22 are provided. A plurality of support frames 21 are installed on the welding table 1 at equal intervals along the length direction of the first positioning block 23. The first positioning rod 22 is provided corresponding to the support frame 21 and is threadedly connected to the support frame 21. The distance between the lower end of the first positioning rod 22 and the welding table 1 is adjusted by rotating the first positioning rod 22. The first positioning block 23 is placed on the welding table 1. A plurality of first positioning grooves 231 are provided on the first positioning block 23 corresponding to the first positioning rod 22. One end of the first positioning rod 22 abuts against the first positioning groove 231, thereby fixing the first positioning block 23.

[0036] like Figure 3 and Figure 4 As shown, the position adjustment mechanism 4 includes a support plate 41 and a telescopic rod 42. The support plate 41, the telescopic rod 42 and the second positioning rod 31 are all provided with a plurality of them.
