The invention discloses a multi-directional deflection bending mechanism for bending a wire. The mechanism comprises a forward bending device for upwards bending the wire, and a reverse bending device for downwards bending the wire; the forward bending device includes a center pin positioned above the wire, and a bending pin upwards rotating around the center pin and positioned below the wire; and the reverse bending device includes a center pin positioned below the wire, and a bending pin downwards rotating around the center pin and positioned above the wire. The multi-directional deflection bending mechanism is mainly applied to bending formation of such wires as reinforcements, can automatically bend the wires to multiple shapes without needing repeated loading and unloading, is simple in operation and convenient for control, and effectively improves the efficiency.
