[0002] A hair straightener is a commonly used device for straightening and straightening hair. Existing hair straighteners generally include two rotatably connected hairpins, with a heating body provided on opposite sides of the hairpins. When in use, the hair is clamped between the two hairpins and the heat emitted by the heating body drags the hair to achieve straightening or straightening of the hair. However, the temperature of the heating body of such existing hairpins is often high, which can easily damage the hair during use, causing problems such as dry, yellow, and dehydrated hair. To solve this problem, a hair straightener that straightens or straightens the hair with hot air can effectively avoid the problem of hair damage caused by direct contact of the heating body with the hair.
[0003] The hairpin plate of the existing hair straightener is generally provided with a clamping strip for clamping hair. The clamping strip may be fixed on the hairpin plate or supported by a spring and arranged in a strip-shaped mounting groove. However, it is difficult to adjust the clamping force of the hair after the hairpin plate is fully clamped. Different users have different requirements for the clamping force, and the clamping elastic force cannot be adjusted according to the user's usage requirements. Summary of the invention
