This patent can be appropriately adjusted according to the length of the metal workpiece by setting a first motor, a threaded rod, a movable plate, a fixed rod, an adjustment seat, a clamp and a hydraulic telescopic rod. At the same time, it can meet the needs of adjusting the height of the worktable. When welding the metal workpiece, the threaded rod is rotated by driving the first motor, and the slider and the movable plate connected by the outer thread are driven to adjust left and right under the rotation of the threaded rod to adjust to the appropriate position of the metal plate welding clamp, and then the movable clamp is squeezed and clamped to the top surface of the metal plate under the adjustment of the adjustment seat by rotating the adjustment seat, and at the same time, the movable clamp and the fixed clamp are adjusted. The surface of the slide is provided with an anti-skid pad so that the metal plate is in a stable fixed state. During the welding process, the second slide slot can be driven to move up and down by the hydraulic telescopic rod so as to be adjusted according to the use habits of the staff, thereby effectively improving the welding efficiency of the metal workpiece; by providing a fixed rod, a driven gear, a driving gear and a second motor, the front and back sides of the metal workpiece can be welded to improve the welding efficiency. When in use, the driving gear is rotated by driving the second motor, and the driving gear and the driven gear are meshed and connected, so that the driven gear further drives the fixed rod to rotate, so as to weld the front and back sides of the metal workpiece, thereby improving the welding work efficiency and reducing the waste of time.

[0004] However, in the above patent, metal objects of different shapes and sizes cannot be clamped and fixed during use, so its applicability is poor. Utility Model Content
