         7 . The hand grip ring according to  claim 5 , wherein each of the two gripping portions of the first gripping portion group has a centerline, each of the two gripping portions of the second gripping group has a centerline, wherein when said first gripping portion group is griped and pressed along a first direction passing through the centerlines of the two gripping portions of the first gripping portion group, the two gripping portions of the second gripping group are respectively folded with respect to a second direction passing through the centerlines of the two gripping portions of the second gripping group to reduce the corresponding concave grooves, wherein when said second gripping group is griped and pressed along the second direction passing through the centerlines of the two gripping portions of the second gripping group, the two gripping portions of the first gripping portion group are respectively folded with respect to the first direction passing through the centerlines of the two gripping portions of the first gripping portion group to reduce the corresponding concave grooves. 
     
     
         8 . The hand grip ring according to  claim 6 , wherein an area size of a cross section along the centerline of each of the two gripping portions of the first gripping portion group is different from an area size of a cross section along the centerline of each of the two gripping portions of the second gripping group. 
     
     
         9 . The hand grip ring according to  claim 1 , wherein an inner surface of each of the two gripping portions of the first gripping portion group has a valley position, two peak position at two sides of the valley position, two transition surfaces each is extended between the valley position and the corresponding peak position to define a concave groove. 
     
     
         10 . The hand grip ring according to  claim 1 , wherein each of the two gripping portions of the first gripping portion group comprises a gripping body and a protruding portion integrally extended from the gripping body to define a concave groove. 
     
     
         11 . The hand grip ring according to  claim 1 , further comprising one or more gripping portion group each comprising two gripping portions arranged between the first gripping portion group and the second gripping portion group. 
     
     
         12 . The hand grip ring according to  claim 1 , further comprising a third gripping portion group each comprising two gripping portions arranged opposite to each other and a fourth gripping portion group each comprising two gripping portions arranged opposite to each other. 
     
     
         13 . The hand grip ring according to  claim 1 , further comprising a third gripping portion group each comprising two gripping portions arranged opposite to each other and a fourth gripping portion group each comprising two gripping portions arranged opposite to each other, wherein the two gripping portions of the third gripping portion group has a concave groove defined between one peak position of the first gripping portion group and one adjacent peak position of the second gripping group. 
     
     
         14 . The hand grip ring according to  claim 5 , wherein a groove depth of the concave groove of each gripping portion of each of the third gripping portion group and the fourth gripping portion group is larger than a groove depth of the concave groove of each gripping portion of each of the first gripping portion group and the second griping group. 
     
     
         15 . A hand grip ring comprising a gripper ring body, wherein at least one concave groove is formed at an inner side of the gripper ring body to guide deformation of the gripper ring body. 
     
     
         16 .
