The rotating module includes a first rotating part and a second rotating part that are coupled together. The first rotating part moves the display around a first axis. The second rotating part moves the display around a second axis. Therefore, the display can be completely adjusted for not only the location but also the viewing angle. ## Claims ### Claim 1 A rotating module used in a portable communication device, wherein said portable communication device includes a base module and a cover, wherein said cover has a first coupling part and said base module has a second coupling part and a third coupling part respectively coupling with the two ends of said first coupling part, wherein said third coupling part is separable from said first coupling part, comprising: a first rotating part coupling with said cover, wherein said first rotating part rotates around a first axis, wherein when said third coupling part couples with said first coupling part, said first rotating part may bring said cover to rotate around said first axis to cover said base module; and a second rotating part fixing in said second coupling part and coupling with said first rotating part, wherein said second rotating part rotates around a second axis, wherein when said third coupling part separates from said first coupling part, said second rotating part may bring said cover to rotate around said second axis to make said cover parallel with said base module. ### Claim 2 (depends on 1) The rotating module of claim 1, wherein said first axis is perpendicular to said second axis. ### Claim 3 (depends on 1) The rotating module of claim 1, wherein said first rotating part further comprises a rotating means and a fixed means, wherein said fixed means is fixed in said second rotating part and said rotating means is used to bring said cover to rotate around said first axis. ### Claim 4 (depends on 1) The rotating module of claim 1, wherein said second rotating part further comprises a fixed means and a rotating means, wherein said fixed means is fixed in said base module and said rotating means is coupled with said first rotating part for bringing said cover to rotate around said second axis. ### Claim 5 (depends on 1) The rotating module of claim 1, wherein said first rotating part may rotate said cover from 0 to 180 degrees. ### Claim 6 (depends on 1) The rotating module of claim 1, wherein said second rotating part may rotate said cover from 0 to 180 degrees. ### Claim 7 A portable communication device, comprising: a cover with a first coupling part and a display embedded in said cover; a base module with a second coupling part and a third coupling part respectively coupling with the two ends of said first coupling part, wherein said third coupling part is separable from said first coupling part; a first rotating part coupling with said cover, wherein said first rotating part rotates around a first axis, wherein when said third coupling part couples with said first coupling part, said first rotating part may bring said cover to rotate around said first axis to cover said base module; and a second rotating part fixing in said second coupling part and coupling with said first rotating part, wherein said second rotating part rotates around a second axis, wherein when said third coupling part separates from said first coupling part, said second rotating part may bring said cover to rotate around said second axis to make said cover parallel with said base module. ### Claim 8 (depends on 7) The portable communication device of claim 7, wherein said first axis is perpendicular to said second axis. ### Claim 9 (depends on 7) The portable communication device of claim 7, wherein said first rotating part further comprises a rotating means and a fixed means, wherein said fixed means is fixed in said second rotating part and said rotating means is used to bring said cover to rotate around said first axis. ### Claim 10 (depends on 7) The portable communication device of claim 7, wherein said second rotating part further comprises a fixed means and a rotating means, wherein said fixed means is fixed in said base module and said rotating means is coupled with said first rotating part for bringing said cover to rotate around said second axis. ### Claim 11 (depends on 7) The portable communication device of claim 7, wherein said first rotating part may rotate said cover from 0 to 180 degrees. ### Claim 12 (depends on 7) The portable communication device of claim 7, wherein said second rotating part may rotate said cover from 0 to 180 degrees.
