The crimper of claim 8, characterized in that two of said first wave crest portions (201) have the same cross-sectional thickness, said first wave trough portion (202) has a larger cross-sectional thickness than said first wave crest portions (201), and said first wave trough portion (202) has a first cavity (204) for accommodating said heat generating component; the two second crest portions (301) have the same cross-sectional thickness, the cross-sectional thickness of the two second crest portions (301) is larger than that of the second crest portions (301), and the two second crest portions (301) are respectively provided with a second cavity (303) and a third cavity (304) for accommodating the heat generating component; the heating component comprises three heating pieces (6), and the three heating pieces (6) are respectively arranged in the first cavity (204), the second cavity (303) and the third cavity (304).

10. The curling iron of claim 9, wherein each of said heat generating members (6) is provided with a resilient member (7), and three of said heat generating members (6) are respectively fixed in said first cavity (204), said second cavity (303) and said third cavity (304) by said resilient members (7).
