[0042] Among them, the heating clamp 20 includes a first clamping plate 21 and a second clamping plate 22 which are symmetrically arranged. The first clamping plate 21 and the second clamping plate 22 are both arranged in the limiting cavity 130. The first end of the first clamping plate 21 and the first end of the second clamping plate 22 are both rotatably connected to the rotating member 12. The second end of the first clamping plate 21 and the second end of the second clamping plate 22 are both provided with a heating plate 23 for heating hair.

[0043] Among them, the pressing clamp 30 includes a first handle 31 and a second handle 32 which are symmetrically arranged, the first clamp plate 21 is arranged on one side of the front end opening 131 of the limiting cavity 130, and the second clamp plate 22 is arranged on one side of the rear end opening 132 of the limiting cavity 130, and the first end of the first handle 31 and the first end of the second handle 32 are both rotatably connected to the positioning member 11.
