The invention discloses a welding fixing graphite fixture and a using method thereof. The welding fixing graphite fixture comprises a working platform. An upward first folding rod is mounted on one side of the upper surface of the working platform. An inner cavity is formed in the working platform. A cylinder is arranged in the inner cavity. An upward second folding rod is connected to the side, penetrating through the working platform, of a piston rod in the cylinder. The second folding rod and the first folding rod are of the same structure and each comprise a first supporting rod and a second supporting rod. A groove is formed in one side of each first supporting rod. One end of each second supporting rod is located in the corresponding groove. The second supporting rods are rotatably connected with the first supporting rods through first rotary shafts. By adoption of the welding fixing graphite fixture and the using method thereof, pulling scratches of welding spots, pseudo soldering and insufficient welding tension can be avoided in the welding process, and a correction function is achieved; and multiple sets of products can be welded at a time, so that the work efficiency isimproved.
