[0019] As a preferred option, further, two sets of angle adjustment structures are provided: an angle fixing seat 5, an angle movable plate 6, and an angle fixing ruler 7. The angle fixing seat 5 is installed on the side wall of the transport platform 4, the angle movable plate 6 is movably installed inside the angle fixing seat 5 via a shaft, and the angle fixing ruler 7 is installed on the lower wall of the angle movable plate 6. The angle fixing ruler 7 passes through the clearance square hole of the transport platform 4. The front and rear walls of the angle fixing ruler 7 are provided with frosted surfaces, and the side of the angle fixing ruler 7 is provided with scale lines.

[0020] As a preferred embodiment, the two sets of material fixing structures further include: a material fixing seat 8, a material magnetic chuck 9, and a material baffle 10; the material fixing seat 8 is installed on the upper wall of the angle movable plate 6, the material magnetic chuck 9 is fixedly installed inside the material fixing seat 8, and the material baffle 10 is installed at the bottom of the material fixing seat 8.

[0021] As a preferred option, the two sets of angle fixing structures further include: an angle fixing support plate 11, an angle fixing bolt 12, and an angle fixing head 13; the angle fixing support plate 11 is installed on the upper wall of the transport platform 4, the angle fixing bolt 12 is installed inside the angle fixing support plate 11 by means of threads, the angle fixing head 13 is installed on the inner side of the angle fixing bolt 12, and the inner wall surface of the angle fixing head 13 is provided with a frosted surface.

[0022] Working Principle: When using this invention, the operator first turns handle 14, causing the carrier screw 2 to rotate. Under the action of the screw, the carrier platform 4 moves outside the carrier screw 2 and carrier guide rod 3. At this time, the two carrier platforms 4 move to their outermost initial positions. The operator then places the flat automotive part to be welded on the upper wall of the material magnetic chuck 9, and places the lower end of the flat automotive part above the material baffle 10. The operator then adjusts the angle according to the welding angle of the flat automotive part. The formula for adjusting the angle is: the adjustment angle is 90 degrees minus half of the welding angle. For example, to weld two flat car parts at a 60-degree angle, subtract half of 60 degrees from 90 degrees to adjust the angle to 60 degrees. To weld two flat car parts at a 120-degree angle, subtract half of 120 degrees from 90 degrees to adjust the angle to 30 degrees. The operator can adjust the angle according to the scale on the side of the angle fixing ruler 7. Then, by rotating the two angle fixing bolts 12, the operator makes the two angle fixing heads 13 respectively lock onto the outside of the angle fixing ruler 7. At this time, the angle fixing ruler 7 is fixed. The contact surfaces of the angle fixing heads 13 and the angle fixing ruler 7 are both frosted surfaces, thus providing greater friction. Next, the operator turns the two handles 14, which drives the carrier screw 2 to rotate. Under the action of the thread, the carrier platform 4 moves outside the carrier screw 2 and the carrier guide rod 3. At this time, the two carrier platforms 4 are brought closer until the welding lines of the two flat car parts are aligned. Then, the operator uses the material magnetic chuck 9 to fix the two flat car parts. Then, the operator can weld the welding lines of the two flat car parts.
