The end of each rib 400 extends through the end of the outer layer 110 and the ear band 300 and abuts the surface of the outer layer 110. That is, each reinforcing rib 400 reinforces one ear band 300. Both ends of the reinforcing rib 400 penetrate both ends of the ear band 300, respectively, and both end portions of the reinforcing rib 400 penetrating the ear band 300 are bent inward to abut against the surface of the outer layer 110. Thus, the reinforcing ribs 400 reinforce the ends of the ear band 300 and prevent the ear band 300 from being pulled off the surface of the outer layer 110. In addition, through the characteristics that strengthening rib 400 is deformable and can keep the posture after the deformation, promoted the laminating degree to the face cheek when wearing cover body 100 to the user, and then promoted laminating protective effect. Thus, the fixing effect on the ear band 300 is strengthened, and the wearing fit degree of the cover body 100 is improved.
To improve the strength and toughness of the reinforcing bar 400, in one embodiment, the reinforcing bar 400 includes a plastic bar 410 and a metal wire 420, and the metal wire 420 is embedded in the plastic bar 410.
