The hair curler according to claim 1, wherein said curling bar is equipped with a U-shaped groove extending axially to an end thereof, said U-shaped groove passes through opposite radial sides of said curling bar and respectively corresponds to said side notch, and said hair fork is provided with an avoiding space preventing said hair from entering said U-shaped groove.
  • 3. The hair curler according to claim 2, wherein said bottom surface of said U-shaped groove is obliquely arranged, having a proximal point close to said side notch and a distal point far away from said side notch, and said horizontal position of said distal point is higher than that of said proximal point.
  • 4. The hair curler according to claim 2, wherein said hair fork is provided with a magnet, said out cylinder is equipped with a Hall sensor in telecommunication connection with said circuit board; when said hair fork turns an angle until said avoiding space corresponds to said side notch, said Hall sensor sense said magnet and transmits a signal to said circuit board so as to control said hair fork to stop rotating by said driving assembly.
  • 5. The hair curler according to claim 4, wherein said hair fork includes a rotating base and two shifting pieces extending from one side of said rotating base; said rotating base is connected to said driving assembly; said two shifting pieces are spaced apart from each other to form two of said avoiding spaces facing each other, upper ends of said two shifting pieces are both provided with hooks for catching hair.
  • 6. The hair curler according to claim 3, wherein said horizontal position of said distal point is flush or tends to be flush with said end of said hair fork.
  • 7. The hair curler according to claim 1, wherein said end of said curling bar extends out to said first cavity and forms a holding part for a finger.
  • 8. The hair curler according to claim 1, wherein said heating member is a PTC electrical corrugated heating element, formed with an airflow cavity for airflow to pass through.
  • 9. The hair curler according to claim 1, wherein one side of said hair fork extends at least two shifting pieces.
