[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 6 A handle rotation structure of a hair dryer comprises a hair tube 1 and a handle 2. A rotating connection part 3 is arranged on the side of the hair tube 1. The rotating connection part 3 is in the shape of an upright circular ring. A through hole is provided between the top of the rotating connection part 3 and the hair tube 1. The handle 2 is rotatably connected to the rotating connection part 3. An elastic ring 4 is arranged on the rotating connection part 3. The center of the elastic ring 4 is located at the rotation center of the handle 2. The inner wall of the elastic ring 4 is provided with a plurality of positioning notches 41. A positioning member 5 is arranged on the handle 2. The positioning member 5 is located in the elastic ring 4. The outer wall of the positioning member 5 is provided with a positioning convex part 51 which is embedded in the positioning notch 41 to limit the position of the hair tube 1 and the handle 2. The number of the positioning notch 41 and the positioning convex part 51 can be set according to the angle at which the handle 2 needs to be positioned. When the handle 2 rotates, the positioning member 5 is driven to rotate. The positioning member 5 squeezes the elastic ring 4 to deform, changes the position of the positioning convex part 51, and positions the positioning convex part 51 through the positioning notch 41, so that the handle 2 can be positioned to a certain extent at multiple positions, so that the handle 2 can be positioned at the unfolded position and the folded position.

[0021] In this embodiment, four positioning notches 41 are evenly arranged on the inner wall of the elastic ring 4, and two positioning protrusions 51 are arranged opposite to each other on the outer wall of the positioning member 5. The two positioning protrusions 51 are located in two of the positioning notches 41 when the handle 2 is perpendicular to the wind tube 1, and the two positioning protrusions 51 are located in the other two positioning notches 41 when the handle 2 is parallel to the wind tube 1. With this structure, the handle 2 can be positioned only in the unfolded position and the folded position.

[0022] In this embodiment, a through hole 31 is provided on the rotation connection part 3, and the handle 2 includes a first handle shell 21 and a second handle shell 22. The first handle shell 21 and the second handle shell 22 are connected from both sides of the rotation connection part 3 by buckles and / or screws. A rotation shaft 23 passing through the through hole 31 is connected between the first handle shell 21 and the second handle shell 22. In this embodiment, the first handle shell 21 and the second handle shell 22 are connected and fixed by buckles and screws. The adoption of this structure makes it easier to realize the rotation connection between the rotation connection part 3 and the handle 2, and convenient to assemble.

[0023] In this embodiment, the handle 2 includes a handle cover 24 which is sleeved on the outside of the first handle shell 21 and the second handle shell 22 and fixedly connected by buckles. The use of this structure makes the handle 2 more beautiful as a whole.

[0024] In this embodiment, four first positioning grooves 32 are evenly arranged around the rotation center on the rotating connection part 3, and four first positioning protrusions 42 are arranged on the side of the elastic ring 4. The first positioning protrusions 42 are inserted into the first positioning grooves 32 for positioning. This structure facilitates the assembly and positioning between the rotating connection part 3 and the elastic ring 4. During installation, the first positioning protrusions 42 on the elastic ring 4 are aligned with the first positioning grooves 32 and inserted, and the outer side of the first positioning protrusions 42 is pressed by the handle 2 to complete the positioning.

[0025] In this embodiment, the handle 2 is provided with a plurality of second positioning grooves 211, and the side wall of the positioning member 5 is provided with a plurality of second positioning protrusions 52 inserted into the second positioning grooves 211. This structure facilitates the assembly and positioning between the handle 2 and the positioning member 5.

[0026] In this embodiment, the positioning member 5 is in a circular ring shape, and has a fracture 53. With this structure, when the positioning member 5 rotates and squeezes the elastic ring 4 to deform, the fracture 53 can also exert a certain degree of elastic force, so that the deformation of the positioning member 5 produces a certain buffering effect, making the handle 2 feel better when rotating.

[0027] In this embodiment, the second positioning groove 211 is provided with a guide slot 212 extending inwardly from the side thereof. With this structure, when the positioning member 5 is deformed, the second positioning protrusion 52 can move along the guide slot 212, so that the deformation buffering effect is better when the positioning member 5 rotates.

[0028] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
