[0011] Further, the basic wrapping module, the N-shaped outer expansion module and the M-shaped outer expansion module are all made of elastic material. The material of the basic wrapping module is thermoplastic polyurethane (TPU) or polyvinyl chloride (PVC).

[0012] Further, the basic wrapping module is provided with a breathable hole to improve the air permeability of the shoe heel shaper when it is combined with other face cloth to form a shoe back.

[0013] Further, the first connecting part, the second connecting part or the third connecting part are mutually glued through an adhesive layer; or the first connecting part, the second connecting part or the third connecting part are mutually attached through hot pressing; or the first connecting part, the second connecting part or the third connecting part are mutually connected through a magic tape, a snap or a plug-in structure.

[0014] Further, the thickness of the N-shaped outer expansion module and the M-shaped outer expansion module is 0.5-2.0mm, and the edge is provided with a chamfer structure.

[0015] The beneficial effects of the utility model are as follows: through the modular design, the basic wrapping module can be used alone or in combination with the N-shaped outer expansion module, the M-shaped outer expansion module or other shape outer expansion module according to actual needs, which effectively improves the versatility and flexibility of the shoe heel shaper, reduces the types of shoe heel shapers and the development number of molds, thereby significantly reduces the manufacturing cost, and has important application value for the shoemaking industry.
