Universal hinge mechanism

The utility model discloses a universal hinge mechanism, relates to novel building connecting piece field, including main plate and two connecting piece, the both sides of main plate are both fixedly connected with rotatory connection bulge, the upper and lower surface of two connecting piece opposite side are both fixedly connected with rotatory butt joint block, and the rotatory butt joint block is connected with the rotatory butt joint block. Connecting round openings are formed in the upper surfaces of the multiple rotating butt joint blocks and the upper surfaces of the two rotating connecting protrusions, and connecting shafts are jointly and rotationally connected between the inner walls of the two rotating connecting protrusions and the two corresponding rotating butt joint blocks through the connecting round openings. The universal angle mechanism is adopted, the problem of splicing of rod pieces at any angle is solved, splicing at any angle can be achieved through one set of mechanism, one set of di
