The output shafts of the two first motors 1411 drive the two lead screws 1410, so that the two moving blocks 1412 move. The two loop-shaped adjusting plates 1413 and the loop-shaped limiting plate 1415 move the drawing frame to the next point position. The first electric push rod 1417 descends to continue dotting. And the output shaft of the second motor 1418 drives the receiving handle 1421, and the connecting pen 1420 faces the previous point position. The output end of the second electric push rod 1422 is pushed out so that the connecting pen 1420 is directly above the previous point position. Continue to lower the output shaft of the first electric push rod 1417 so that the convex slide rod 1423 partially contracts into the concave inner groove, that is, the connecting pen 1420 touches the previous point position. The output shaft of the second motor 1418 contracts, and the connecting pen 1420 connects two adjacent point positions.
