9. A use method of a portable drawing box for architectural design is characterized by comprising the following specific steps:

the method comprises the following steps: firstly, the box cover (2) is opened, when the box cover (2) is opened to ninety degrees, the box cover (2) can be abutted by the limiting abutting block (40), the iron absorbing sheet (6) is absorbed by the absorbing magnet (12) through the arrangement of the iron absorbing sheet (6) and the absorbing magnet (12), when the base plate (5) is accommodated in the accommodating groove (11), the iron absorbing sheet (6) is absorbed by the absorbing magnet (12), so that the base plate (5) is fixed, and the base plate (5) is upwards broken after the box cover (2) is opened, so that the base plate (5) rotates around the rotating shaft (10);

step two: after the backing plate (5) is broken off, the deflection rod (15) is rotated to be moved out of the strip-shaped groove (13), at the moment, the rotating sleeve (25) is rotated to be rotated on the limiting ring (24) at the top end of the deflection rod (15), the lifting screw (17) is moved out of the accommodating hole (16), the lifting screw (17) is moved out to jack up the two clamping rods (19) upwards through the connecting wafer (18), and when the clamping rods (19) are lifted to a proper height, the locking screw (22) can be clamped in the bayonet (8) of the connecting block (7);

step three: when the locking screw rod (22) is clamped in the bayonet (8), one side of the base plate (5) is erected on the clamping rod (19), so that the base plate (5) is supported by the clamping rod (19), and then the rotating sleeve (25) is rotated again, so that the clamping rod (19) moves again and the height of the jacking base plate (5) is adjusted;

step four: after the inclination angle of the backing plate (5) is adjusted, the knob (23) is rotated to enable the locking screw (22) to be screwed into the nut (21) and screwed, and the top ends of the two clamping rods (19) clamp the connecting block (7) so as to fix the position of the backing plate (5);

step five: the backing plate (5) is fixed back, will place box (37) through fixed (39) and mention to will place box (37) and erect in box (1) both sides, make the edge card of box (1) in draw-in groove (38), thereby make two place box (37) tiling in box (1) both sides.
