       wherein the deforming section comprises a plurality of elastic members; when at least one of the first resisting section and the second resisting section are stressed, the deforming section deforms through deformation of the elastic members. 
     
     
         9 . The protecting cover of  claim 8 , wherein the protecting cover further comprises:
 a first block member connected between an upper end of the first packaging liner and an upper end of the second packaging liner;   a second block member connected between a lower end of the first packaging liner and an lower end of the second packaging liner;   a third block member connected to an inner and upper side of the connecting packaging liner; and   a fourth block member connected to an inner and lower side of the connecting packaging liner.   
     
     
         10 . The protecting cover of  claim 8 , wherein each of elastic members comprises:
 a first extension arm;   a second extension arm; and   a connecting portion;   wherein an end of the first extension arm and a corresponding end of the second extension arm are connected by the connecting portion; and an interspace is defined between the first extension arm and the second extension arm.   
     
     
         11 . The protecting cover of  claim 10 , wherein the plurality of elastic members is integrally punch-formed. 
     
     
         12 . The protecting cover of  claim 10 , wherein the interspace is an oval punched hole. 
     
     
         13 . The protecting cover of  claim 8 , wherein the connecting portion defines a first arc-shaped gap thereon, the first arc-shaped gap and the interspace are adjacent to and in air communication with each other, two ends of the first arc-shaped gap respectively extends to the first extension arm and the second extension arm. 
     
     
         14 . The protecting cover of  claim 8 , wherein each connecting portion of the deforming section and the first resisting section define a second arc-shaped gap, each connecting portion of the deforming section and the second resisting section define a second arc-shaped gap.
