[0018] 4. The present invention can adjust the position of the upper plate through the coordinated activities between the disc rail and the side group slideway, so that the upper plate can be adjusted horizontally to change the use position of the upper plate. At the same time, threaded columns are designed at both ends of the welding mechanism, and the bottom end part and the top end part of the threaded column are threadedly connected and can be rotatably adjusted.
