the rotating member is pivotally provided on the rotary portion of the spindle;

the limit mechanism comprises a limit block provided on the fixing member and a rotatable limit component pivotally provided on the rotary portion of the spindle and provided with a radially protruding first protruding block;

the rotating member is coupled to the rotatable limit component and leaves some rotating space, when the rotary wing drives the rotating member rotating, it further drives the rotatable limit component rotating, and when the first protruding block provided on the rotatable limit component is blocked by the limit block provided on the fixing member, the rotary wing has rotated through 180 degrees.

8. The rotary-wing type mobile telephone as claimed in claim 7, wherein the rotatable limit component is ring-shaped rotatable limit member, the rotating member is formed at an end surface thereof adjacent to the rotatable limit member with an axially extending ring-shaped protrusion which is provided with an opening, the first protruding block of the rotatable limit member is embedded in the opening whose width is larger than that of the first protruding block;

when the rotating member rotates about the spindle, the ring-shaped protrusion comes into contact with the protruding block to drive the rotatable limit member rotating.

9. The rotary-wing type mobile telephone as claimed in claim 7, wherein the rotatable limit component in turn comprises a first rotating member, a rotatable limit member and a second rotating member;

the second rotating member is fixedly connected to the rotating member and formed at the interior circumference thereof with a plurality of first open slots;

the first protruding block of the rotatable limit component is formed on the rotatable limit member which is formed at the interior circumference thereof with a plurality of second open slots in correspondence with the locations of the first open slots;
