         3 . The automatic hair curler of  claim 2 , wherein the rotating seat comprises:
 a sleeving part that is sleeved on an outer ring of the bearing, the sleeving part of the rotating seat being fixed to the gear; and   at least one shifting piece distributed on the periphery of the sleeving part and extending outwardly from the sleeving part, wherein the hair curling cavity is located between an inner surface of the shifting piece and the outer surface of the heating rod.   
     
     
         4 . The automatic hair curler of  claim 3 , wherein the sleeving part is fixedly connected with the outer ring of the bearing. 
     
     
         5 . The automatic hair curler of  claim 1 , wherein the rotating seat comprises:
 a sleeving part disposed within a portion of the handle;   a shifting piece disposed around the heating rod and extending from the sleeving part, the shifting piece comprising a plurality of projections convexly arranged on a side wall of the shifting piece;   the hair curling cavity formed between an inner surface of the shifting piece of the rotating seat and the outer surface of the heating rod.   
     
     
         6 . The automatic hair curler of  claim 1 , wherein the rotating seat comprises:
 a sleeving part disposed within a portion of the handle;   a shifting piece disposed around the heating rod and extending from the sleeving part;   an elastic piece gradually inclined outwards from an upper end of the shifting piece; and   a shifting part located at a juncture between the shifting piece and the elastic piece;   the hair curling cavity formed between an inner surface of the shifting piece of the rotating seat and the outer surface of the heating rod.   
     
     
         7 . The automatic hair curler of  claim 1 , further comprising a cover body installed at a top end of the heating rod, wherein an outer surface of the cover body is an arc surface. 
     
     
         8 . The automatic hair curler of  claim 1 , further comprising a notch extending downwards from a top end face of the shell, the notch being in communication with the hair curling cavity. 
     
     
         9 . The automatic hair curler of  claim 1 , further comprising a positioning elastic part extending from the inner surface of the rotating seat into the hair curling cavity. 
     
     
         10 . An automatic hair curler, comprising:
 a handle;   a heating rod extending from the handle;   a rotating seat extending at least partially around a circumference of the heating rod and extending a height from the handle at least partially overlapping a height of the heating rod; and   a hair curling cavity formed between an inner surface of the rotating seat and an outer surface of the heating rod.   
     
     
         11 . The automatic hair curler of  claim 10 , further comprising a shell mounted to the handle, the shell extending a height greater than the height of the heating rod from the handle. 
     
     
         12 . The automatic hair curler of  claim 11 , wherein the shell comprises a notch extending from an upper end of the shell towards the handle, the notch being in communication with an opening of the hair curling cavity. 
     
     
         13 . The automatic hair curler of  claim 11 , wherein the shell extends entirely around the circumference of the heating rod. 
     
     
         14 . The automatic hair curler of  claim 11 , wherein the shell is radially spaced apart from the heating rod. 
     
     
         15 . An automatic hair curler, comprising:
 a handle;   a heating rod extending from the handle;   a rotating seat extending at least partially around the heating rod; and   a hair curling cavity formed between an inner surface of the rotating seat and an outer surface of the heating rod, the hair curling cavity having an opening formed at an upper end of the rotating seat opposite the handle.   
     
     
         16 . The automatic hair curler of  claim 15 , wherein the rotating seat comprises:
 a sleeving part rotatably mounted to the handle; and   at least one shifting piece extending outwardly from the sleeving part and at least partially around a circumference of the heating rod.   
     
     
         17 . The automatic hair curler of  claim 16 , wherein the rotating seat comprises two space apart shifting pieces. 
     
     
         18 . The automatic hair curler of  claim 16 , wherein the at least one shifting piece extends the entire circumference of the heating rod.
