The utility model discloses a multidirectional coupler and aims at solving the problem that a multidirectional coupler is complex in structure in the prior art. The multidirectional coupler comprises a machine frame, a driving shaft and a driven shaft, and is characterized by further comprising an annular sliding groove, sliding blocks, a pin rod and a bracket, wherein the annular sliding groove is connected with the driving shaft, the sliding blocks are matched with the annular sliding groove, the pin rod is connected with the driven shaft, and the bracket is connected with the driven shaft in a rotating mode. The track axis of the annular sliding groove is perpendicular to the axis of the driving shaft, the pin rod is connected with the sliding blocks in a rotating mode, the bracket is connected with the machine frame through a first rotation pair, and the axis of the driving shaft, the track axis of the annular sliding groove, the axis of the pin rod, the axis of the driven shaft and the rotation axis of the first rotation pair intersect at one point. The multidirectional coupler has the advantage that the driving shaft and the driven shaft can transmit torque and rotate at various intersection angles by adjusting the direction of the bracket.
