Marking device for engineering project

The scribing device for the engineering project comprises a vertical rod, first screw rods are symmetrically connected to the two sides of the lower portion of the vertical rod, adjusting nuts are arranged on the first screw rods in a threaded connection mode, a supporting seat is arranged at the ends, away from the vertical rod, of the first screw rods in a sliding connection mode, and screw holes are formed in the ends, away from the screw rods, of the supporting seat. A height adjusting device is arranged in the screw hole in a threaded connection mode, the bottom of the vertical rod is connected with a scribing box below the supporting seat, the top in the scribing box is connected with a motor, and the power output end of the motor is connected with a penholder plate. Compared with the prior art, the adjustable marking device has the advantages that the distance between the two groups of supporting legs can be adjusted, the marking height can be adjusted, and the surfaces of objects with different height
