In the present invention, the initial position of the second chuck 20 is deviated from the middle of the cross section of the workpiece toward the rear side of the workpiece, so that the workpiece 38 is placed on the second chuck 20, and the workpiece is supported more stably to prevent the workpiece from being turned upside down or skewed because the distance between the second chuck 20 and the first chuck 19 is relatively large. After the workpiece is placed stably, the motor 23 drives the rotating shaft 24 to rotate again, the rotating shaft 24 drives the first driving wheel 25 and the second driving wheel 26 to rotate in the same direction, and the two driving wheels respectively drive the first rack 28 and the second rack 30 to move in the same direction, so that the third chuck 21 compresses the rear side wall of the workpiece, and the second chuck 20 moves to be close to the middle part of the cross section of the workpiece, so that the workpiece is continuously and reliably supported, and at the moment, the second chuck 20 is far away from the edge position of the workpiece, and welding of the top corner of the workpiece is not interfered.
