Further, the connecting line 23 also serves to limit the relative movement between the layers of the mesh-like structure layer 21, which may cause structural failure, so that the connecting line 23 is required to be made of an inelastic material and have a sufficiently strong tensile property. The embodiment of the present application does not limit the specific material of the connecting line 23, for example, the material of the connecting line 23 may be carbon fiber or other inelastic composite materials with strong tensile properties.
