Description

Technical Field

[0001] The utility model belongs to the technical field of hair straighteners, in particular to a hair clamp plate elastic mechanism of a hair straightener. Background Art

[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 relatively high, which can easily damage the hair during use, leading to problems such as dry and dehydrated hair. To solve this problem, people have developed a hair straightener with a cold air blowing function, the purpose of which is to quickly cool the hair after it is heated, reducing the damage to the hair caused by excessive heating body temperature. There are also some hairpins that straighten the hair by directly blowing out hot air, further avoiding damage to the hair caused by excessive heating body temperature. After adding the blow-drying function, the hair straightener generally includes a handle with a blower inside, and two hairpins connected to the handle. Generally, one of the hairpins is fixed, and the other hairpin is hinged to the handle. The opening and closing is achieved by rotating the hinged hairpin. However, if there is only one hinge point between the hairpin and the handle, the stability is often poor. Summary of the invention
