Because a fretwork head 11 in another fretwork district is equipped with between two adjacent fretwork tails 12 of the same fretwork district of above-mentioned elasticity inner liner, so the afterbody of a fretwork district links to each other with the head of three fretwork district, and in the same way, the head of a fretwork district links to each other with the afterbody of three fretwork district, so a fretwork district links to each other with six fretwork districts altogether, so, the tie point of a fretwork district and other fretwork districts has six, and every tie point all is that three fretwork district shares, so the tie point that every fretwork district monopolizes is two. Compared with the honeycomb regular hexagon hollowed-out net with two connecting points exclusively occupied by each hollowed-out area, under the condition of the same hollowed-out area, the perimeter of the edge of the hollowed-out area is much longer than that of a common honeycomb regular hexagon hollowed-out net, so that the elastic lining layer can deform greatly. Under the condition of the same material, the elastic lining layer is softer than the honeycomb regular hexagon hollowed-out net. Based on the flexibility of the elastic lining layer, the elastic lining layer is used as a lining of a helmet and has a good buffering function, the hollow area of the elastic lining layer is large, the air permeability is good, and plastic raw materials are generally required to be adopted for manufacturing the elastic lining layer, so that the elastic lining layer has the effect of being easy to clean.
