Adjustable industrial box hinge device

According to the adjustable industrial box hinge device, by arranging a driving motor and a worm and gear assembly, starting and stopping of a worm can be autonomously controlled, when the worm rotates, a first worm gear and a second worm gear are driven to rotate reversely at the same time, a first connecting plate and a second connecting plate are driven to rotate reversely at the same time, and a first box plate and a second box plate are driven to rotate reversely at the same time; the rotating angle is controllable, the rotating range is 0-180 degrees, free adjustment of the angles of the box plates can be achieved, and therefore adjustment of the shape of the box body can be achieved, the box plates rotate to be assembled into the box body shape during use, the box plates rotate to form a containing body after use, and therefore the storage space rate of the box body is increased, the assembling efficiency of the box body is improved, and the utilization rate of the box body is increased. And after the
