In use, the horizontal and vertical surfaces of the workpiece to be welded, as well as the holes or protrusions, are placed between the first support 2, the second support 5, the positioning pin 9, and the positioning kit 12, respectively. Then, by pressing the pneumatic valve 14, the cylinder is activated, driving the pressure block 4 to rotate and press it against the top surface of the workpiece. This, in conjunction with the first support 2, vertically limits the workpiece. The pressure plate 7 is driven to move towards the second support 5 to limit the vertical plane of the workpiece. The positioning pin 9 is inserted into the hole on the workpiece and abuts against the outside of the hole through the end face of the positioning kit 12, or it is inserted into the protrusion through the socket of the positioning kit 12. The positioning pin 9 abuts against the inside of the workpiece, completing the positioning of the hole or protrusion on the workpiece and ensuring the positioning strength, so that welding can be carried out.
