and a third step of: the method comprises the steps of forming a frame assembly, firstly, splicing four frame parts obtained in the second step to form a frame assembly of unbent frame parts, enabling a second frame part, a third frame part and a fourth frame part to be respectively embedded into a gap of a first frame part, enabling a reinforcing part to penetrate through all connecting holes, connecting a connecting body in series, enabling adjacent frame parts to be mutually perpendicular on a plane perpendicular to the axis of the reinforcing part, enabling two surfaces of the adjacent frame parts forming a right-angle space to be the upper surface of one frame part and the lower surface of the other frame part; secondly, bending the frame parts, wherein the second combination body of each frame part is bent at right angles along the first folding groove of the frame part, the third combination body of each frame part is bent at right angles along the second folding groove of the frame part, after the right angle bending is finished, the non-bending end of the third combination body of each frame part is close to the right angle bending position of the first combination body of the previous frame part along the clockwise direction on the plane perpendicular to the axis of the reinforcing part, and the first combination body, the second combination body, the third combination body and the first combination body of the previous frame part of each frame part enclose a cavity with square cross section;
fourth step: and forming the butterfly-shaped lead-in optical cable, namely respectively placing four lead-in units in four square cavities, and extruding and coating an outer sheath outside the frame assembly to finish the manufacturing of the four-unit butterfly-shaped lead-in optical cable.

6. A method of manufacturing a four-unit butterfly drop cable according to claim 1, wherein: the material of the reinforcement (32) is copper or aluminum or an alloy or lead or glass fiber reinforced plastic or aramid yarn.
7. A method of manufacturing a four-unit butterfly drop cable according to claim 1, wherein: the height of the butterfly-shaped introducing unit (3) is 2.8-3.2mm.
8. A method of manufacturing a four-unit butterfly drop cable according to claim 7, wherein: the width of the butterfly-shaped introducing unit (3) is 1.8-2.2mm.
9. A method of manufacturing a four-unit butterfly drop cable according to claim 1, wherein: the butterfly sheath (33) is made of plastic.
10. A method of manufacturing a four-unit butterfly drop cable according to claim 9, wherein: the plastic is flame-retardant polyethylene or low-smoke halogen-free polyethylene or polyvinyl chloride or polytetrafluoroethylene.
