Intelligent drawing auxiliary device based on bridge design

The invention discloses an intelligent drawing auxiliary device based on bridge design, and relates to the technical field of design drawing devices. A paper containing groove is fixed to the bottom of the table board in a hoisting mode, a partition plate is arranged in the center of the paper containing groove, the space above the partition plate is used for containing drawn paper, the space below the partition plate is used for containing unused drawing paper, and two transverse supporting mounting plates are fixed to the bottom of the paper containing groove in a front-back spaced mode through screw locking. Two grounding brackets are symmetrically welded at the bottoms of the two transverse support mounting plates; and two cover plates are symmetrically and rotationally installed on the protruding sections of the left ends and the right ends of the two transverse support installation plates, and a pen containing box is slidably installed on the middle portions of the two transverse support installation pl
