Tool for drawing circular intersecting opening line tool through laser scanning

The invention provides a tool for drawing circular intersecting opening line tool through laser scanning. The tool mainly includes an axial positioning rod, a stable support rod, a sliding positioningcard, a rotating plate and a laser pen, wherein the axial positioning rod is sleeved with the sliding positioning card that can slide upwards in the axial direction of the axial positioning rod; thetwo sides of the sliding positioning card are movably connected with two stable support rods; a rotating plate sleeve on the axial positioning rod can axially rotate around the axial positioning rod;and the laser pen is fixedly on the rotating plate. According to the principle of optical straight line, the laser beam emitted by the laser pen is irradiated on an undulating member surface; an operator uses a line drawing slate pencil to draw lines continuously following the position of light spots; it is easy to draw an intersecting opening cut line of a round tube and a complex surface; and openings are cut according to
