The invention discloses a surrounding mechanism of a magnetic ring winding machine. The surrounding mechanism comprises a base; a vertical plate is welded on one side of the top of the base; a first transverse plate is welded on one side of the vertical plate; a first groove is formed in one side of the top of the first transverse plate; a first push rod motor is fixedly mounted on the bottom inner wall of the first groove; a first connecting rod is welded on the output shaft of the first push rod motor; a hook rod is welded on the top of the first connecting rod; a second transverse plate isalso welded on one side of the vertical plate; and the second transverse plate is positioned above the first transverse plate. The surrounding mechanism is convenient to use; a second push rod motor drives a clamping plate to clamp a varnished wire, and a driving motor drives an L-shaped rod to rotate, and next, the first push rod motor drives the hook rod to lift upwards to hook down the varnished wire from the clamping plate and to enable the wire to pass through the magnetic ring, and then, the above steps are executed repeatedly, thereby enabling the varnished wire to be wound on the magnetic ring; and the surrounding mechanism is simple in operation.
