[0013] The top, bottom, left, right, front, and back of this utility model are as described in the appendix to the specification. Figure 1 This explanation is for reference only.

[0014] See attached document Figure 1-4 A square tube welding fixture includes a first groove plate 1 and a second groove plate 2, both of which are square groove plates. The outer walls on both sides of the middle part of the first groove plate 1 are provided with an opening 3 and an opening 4, which correspond to each other. One end of the second groove plate 2 is fixedly connected to the outer walls on both sides of the second opening 4. The first groove plate 1 is provided with two clamping devices 5, which are respectively located on the left and right sides of the front outer wall of the second opening 4. The second groove plate 2 is provided with clamping devices 6 on the left and right side walls respectively.

[0015] The clamping device 5 includes a square plate 7 and a screw 8. The square plate 7 is located inside the slot plate 1 and is vertically arranged. The center of the front side wall of the square plate 7 is perpendicular to the screw 8. The center of the front side wall of the square plate 7 is rotatably connected to one end of the screw 8. The screw 8 has a sliding rod 9 on each side. The front side wall of the square plate 7 is vertically and fixedly connected to one end of the sliding rod 9. Both the screw 8 and the sliding rod 9 pass through the front side wall of the slot plate 1. The screw 8 is threadedly connected to the front side wall of the slot plate 1, and the sliding rod 9 is slidably connected to the front side wall of the slot plate 1. The screw 8 is threadedly fitted with a nut 10 and a nut 21. The nut 10 and the nut 21 are located on both sides of the front side wall of the slot plate 1. The nut 10 and the nut 21 are respectively pressed against the two ends of the front side wall of the slot plate 1. A handle 12 is provided at the front end of the screw 8.

[0016] The clamping device 26 includes a pressing plate 13, a screw 2 14, and a sliding rod 2 15. The pressing plate 13 is inside the groove plate 2. The two sliding rods 2 15 penetrate through the left side wall of the groove plate 2. The screw 2 14 penetrates through the left side wall of the groove plate 2 and is located in the middle of the two sliding rods 2 15. The right end of the sliding rod 2 15 is fixedly connected to the pressing plate 13. The right end of the screw 2 14 is rotatably connected to the pressing plate 13. The screw 2 14 is threadedly fitted with nuts 3 16 and 4 17. Nuts 3 16 and 4 17 are respectively pressed against the two ends of the left side wall of the groove plate 2. The clamping devices 26 on the left and right side walls of the groove plate 2 are symmetrically arranged.

[0017] Working principle: Square tube 18 and square tube 2 19 are placed inside slot 1 and slot 2 respectively. Rotating screws 8 and 14, square plate 7 and extrusion plate 13 pre-clamp square tube 18 and square tube 2 19, allowing them to slide inside slot 1 and slot 2 respectively. Adjusting tube 18 and square tube 2 19 exposes a portion of the weld seam to be welded at opening 3 and opening 4. Rotating screws 8 and 14... 4. Fix square tube 18 and square tube 2 19 inside the slot plate 1 and slot plate 2. Rotate nut 3 16 and nut 4 17, and rotate nut 10 and nut 2 11. This will prevent screw 8 and screw 2 14 from rotating. Use an electric welding machine to weld the seam. After welding part of the seam, remove square tube 18 and square tube 2 19 from inside the slot plate 1 and slot plate 2. At this time, square tube 18 and square tube 2 19 are fixed. Then weld the remaining seam.
