[0023] Example 1:

[0024] like Figure 1-4As shown: The L-shaped plate 1 has an angle adjustment assembly 2 on its bottom surface and a clamping assembly 3 on its top. The angle adjustment assembly 2 includes a support plate 21 fixedly installed on the right side of the top surface of the L-shaped plate 1. A gear 22 is rotatably mounted on the center of the top surface of the support plate 21 via a bearing ring. The clamping assembly 3 is positioned above the gear 22. A first hydraulic rod 23 is fixedly installed on the rear side of the right side wall of the L-shaped plate 1. The output end of the first hydraulic rod 23 penetrates the side wall of the L-shaped plate 1 and is fixedly mounted with a rack plate 24.

Then the junction box is welded. During the welding process, the rack plate 24 is moved by the first hydraulic rod 23. The meshing of the rack plate 24 with the gear 22 can make the gear 22 and the turntable 31 on its top rotate synchronously, thereby adjusting the angle of the junction box to facilitate the welding work and improve the welding quality and speed of the junction box.

[0025] Example 2:

[0026] like Figure 1 , 2 As shown in Figure 4: The clamping assembly 3 includes a turntable 31 fixedly installed in the middle of the top surface of the gear 22. The diameter of the turntable 31 is the same as the diameter of the support plate 21. A mounting hole 32 is provided in the middle of the top surface of the turntable 31. The mounting hole 32 is a blind hole. Symmetrically distributed sliding grooves 33 are provided on the left and right sides of the top surface of the turntable 31. A sliding rod 37 is fixedly installed on the inner wall of the sliding groove 33. A slider 38 is slidably fitted on the outer surface of the sliding rod 37.
