The invention relates to the bridge construction technical field, particularly to a cantilever type multidirectional displacement bolt-free comb plate extensible device and an installation method thereof. The improved cantilever type multidirectional displacement bolt-free comb plate extensible device is of a cantilever type comb tooth structure, comb teeth are symmetrically inserted into directions and do not interfere with each other in force, and the comb teeth are hung in the air and can twist along with a bridge to implement the rotation of multiple directions of the vertical direction, the horizontal direction, the inclined direction and the like of the extensible device so as to adapt to the displacement of the multiple directions of the vertical direction, the horizontal direction, the inclined direction and the like of a beam end of the bridge. The cantilever type multidirectional displacement bolt-free comb plate extensible device is reasonable in structure and the problems of bolt yielding and cutting and head warping of a toothed plate of the extensible device due to the displacement of the multiple directions of the vertical direction, the horizontal direction, the inclined direction and the like of the beam end of the bridge are solved.
