  "claims": [
    "1. A rotatable mobile phone shell, comprising: a shell body having front-opening hollow structure and formed with a coupling through hole on back surface; a rotating component comprising a rotating ring component, a hinge coupling concave portion, and a spring insertion portion, wherein, a peripheral surface of the rotating ring component is capable of rotating with respect to an inner circumferential surface of the coupling through hole, the hinge coupling concave portion is arranged on an inner circumferential surface of the rotating ring component, and the spring insertion portion is formed on the inner circumferential surface of the rotating ring component and communicated to two end portions of the hinge coupling concave portion; a finger gripping component comprising a finger gripping ring, a hinge end, and a spring insertion groove, wherein the hinge end is integrated on a peripheral surface of the finger gripping ring and arranged at the hinge coupling concave portion, the spring insertion groove is formed at the hinge end and one side surface of the finger gripping ring, and configured to communicate one end of the hinge end to the other end of the hinge end through the one side surface of the finger gripping ring; and a spring component inserted into the spring insertion groove and having two end portions forcibly pressed into the spring insertion portion; wherein the inner circumferential surface of the coupling through hole consists of a first two-end circumferential surface portion and a first central circumferential surface portion located at inner side of the first two-end circumferential surface portion; and the first two-end circumferential surface portion is rounded and chamfered, the first central circumferential surface portion is formed to be 0.1-1 mm larger than an inner diameter of the coupling through hole, and a plurality of blocking protrusions spaced at a predetermined distance are formed on the first central circumferential surface portion; wherein the peripheral surface of the rotating ring component consists of a second two-end circumferential surface portion and a second central circumferential surface portion located at inner side of the second two-end circumferential surface portion; and the second two-end circumferential surface portion is rounded and chamfered, the second central circumferential surface portion is formed with a convex portion having semi-arc section in radius direction, and a plurality of blocking grooves spaced at the predetermined distance are formed on the second central circumferential surface portion for insertion or detachment of the blocking protrusions.",
    "2. The rotatable mobile phone shell of claim 1, wherein the finger gripping component further comprises: a pull-out end portion formed as a concave portion or a convex portion at an opposite position of the hinge end on the inner circumferential surface of the finger gripping ring, and a cover protrusion provided on the peripheral surface of the finger gripping ring."

  "description_excerpt": "The invention relates to a rotatable mobile phone shell.\n\nA shell having replaceable module for portable terminal is disclosed in Republic of Korea registered patent No. 1392562. The invented shell comprises: a shell enclosing and protecting the outer surface of a portable terminal; a mounting groove concavely-formed on the back surface of the shell; a connector rotationally connected in the mounting groove; and a replaceable module consisting of an operation portion, wherein the operation portion is rotationally connected relative to the connector, is received in the mounting groove during folding, and has function of holder of the portable terminal during unfolding.\n\nThe prior art has the advantage of unfolding the operation portion by simple operation to support the portable terminal at a desired angle. The replaceable module can be easily replaced and can be manufactured with various designs and functions. The functions of mirror, magnifying lens, traffic card, etc. can be combined in the operation portion of the replaceable module, thereby achieving effect of providing shell with comprehensive applications for portable terminal. On the other hand, to achieve that the connector 310 is rotationally combined with an assembling-disassembling groove 210, the shell becomes thick, at the same time, owing to the tail end rotating manner of the connector 310, the durability is reduced due to repeated use, and the probability of breakage is increased, so that the prior art has the disadvantage of being unstable when it is supported.",
