[0022] Reference Figures 1-4 , rectangular plates 8 are fixed at both ends of the opposite sides of the two rectangular frames 5, and a threaded rod and a guide rod 9 are respectively provided between the two rectangular plates 8. The two ends of the threaded rod rotate with the two rectangular plates 8 thereon, and the two ends of the guide rod 9 are fixedly connected with the two rectangular plates 8 thereon. One end of the threaded rod passes through the rectangular plate 8 and extends outward to be connected to the output end of the motor 7. The outer walls of the threaded rod and the guide rod 9 are both sleeved with movable blocks 6. The movable blocks 6 on the threaded rod are threadedly connected to the threaded rod, and the movable blocks 6 on the guide rod 9 are slidably connected to the guide rod 9. A connecting frame 10 is fixed between the two movable blocks 6. The two ends of the connecting frame 10 are slidably connected to the two rectangular frames 5, wherein the two rectangular plates 8 are fixedly connected to the side rods 15, and a fixed frame 14 is fixed between the two side rods 15.

The top end of the support rod 13 passes through the through-hole 11 and is extended upwardly with a nut. The top surfaces of the connecting frame 10 and the fixed frame 14 are engraved with a scale. By using the scale, the position of the rectangular block 12 in the connecting frame 10 and the fixed frame 14 can be adjusted according to the welding condition of the steel bar.
