It can be understood that, the first layer of preventing falling can do first prevent falling the inside buffer chamber, the buffer air cushion etc. that sets up of angle support 1, the second prevents falling the layer all can be the second prevents falling the inside buffer chamber, the buffer air cushion etc. that sets up of angle support 2, the third prevents falling the layer all can be the inside buffer chamber, the buffer air cushion etc. that set up of angle support 3 is prevented to the third, the fourth prevents falling the layer all can be the second prevents falling the inside buffer chamber, the buffer air cushion etc. that set up of angle support 2. When the cell-phone drops subaerial, the first layer of preventing falling the layer is prevented to the second the layer is prevented to the third and the fourth prevent falling the layer and can play the impact force between four turnings of buffering cell-phone and the ground to can avoid four turnings of cell-phone impaired.

The protection shell of the present invention is merely an embodiment, and is not intended to limit the present invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
