The invention discloses a wire twister which comprises four twisted wire disks arranged on the same hollow shaft, wherein, the concentric periphery of each twisted wire disk is provide with a plurality of conducting wire wheels and/or slotted holes; the conducting wire wheels comprise fixed conducting wire wheels and movable conducting wire wheels, the fixed conducting wire wheels are connected with the twisted wire disks through rollers on the conducting wire wheels, and the movable conducting wire wheels are connected on a sliding block through rollers; the sliding block is matched with a sliding rail block, one side of the sliding rail block is fixed on a connecting plate, and the connecting plate is fixed on the hollow shaft; the axis of the shaft is perpendicular to the radial line of each twisted wire disk; and the end part of the sliding block is provided with an adjusting rod, and the adjusting rod adjusts the sliding block to slide along the radial direction of the connectingplate through an adjusting component arranged on the sliding rail block and/or the connecting plate. By adopting the wire twister, before cables or ropes are twisted, a plurality of the cables are plastically deformed in advance; and in addition, the cables of various specifications can be produced by adjusting the distance among the twisted wire disks and positions of the movable conducting wirewheels.
