The width of the movable groove 16 is smaller than the width of the slide groove 13, so as to prevent the tooth plate 14 from sliding off the slide groove 13 and ensure the sliding stability of the tooth plate 14.

[0023] The left side of the lower end of the toothed plate 14 located on the upper side and the right side of the lower end of the toothed plate 14 located on the lower side are fixedly connected with a vertical rod 17, and the lower end of the vertical rod 17 is fixedly connected with a mounting plate 18.

Under the limit of the square limit groove, the sleeve block 23 is driven to slide horizontally, and the two tooth plates 14 are driven to slide relative to and away from each other through the meshing of the two tooth plates 14 and the gear 15, and the positions of the two mounting plates 18 are adjusted, that is, the positions of the two welding machines 8 are adjusted. When the sleeve block 23 slides to the right, the two tooth plates 14 are driven to slide relative to each other, and the spacing between the two welding machines 8 is reduced. Conversely, the rotating motor 21 drives the threaded rod 22 in the reverse direction, and the spacing between the two welding machines 8 is increased, until the two welding machines 8 are adjusted to a suitable position; Finally, the first electric push rod 6 extends downward to drive the lifting plate 7 to move downward, and drives the two welding machines 8 with adjusted positions to weld the workpieces downward.
