[0002] In conventional hair straighteners, the top and bottom clips are usually hinged together using pins, and the multiple wires connecting the clips typically need to be routed through the hinge joint. However, this structure can cause the wires to obstruct the path when threading the wires through the joint, making assembly inconvenient and even damaging the wires.

[0003] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hair straightener that is simple in structure, easy to assemble, and avoids getting the hair stuck.

[0005] This utility model is achieved through the following technical solution:

[0006] To solve the above-mentioned technical problems, this utility model provides a hair straightener that prevents wire jamming, including an upper clip and a lower clip. A rotating shaft is provided between the upper clip and the lower clip for rotatably connecting the two. An upper housing cover is provided on the inner side of the upper clip.

[0020] Figure 4 This is a three-dimensional structural diagram of the guide section. Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 4 As shown in the figure, this embodiment discloses a hair straightener that prevents wire jamming. It has a simple structure, is easy to assemble, and effectively avoids the problem of wire jamming.

[0023] This hair straightener mainly consists of an upper clamp 1 and a lower clamp 2. The upper clamp 1 and lower clamp 2 are rotatably connected by a pivot 3. Specifically, upper shaft seats 11 are provided on the left and right sides of the upper clamp 1, each with a first shaft hole 111. Similarly, lower shaft seats 21 are provided on the left and right sides of the lower clamp 2, each with a second shaft hole 211. The pivot 3 fits into the two first shaft holes 111 and the two second shaft holes 211, thus ensuring a stable and reliable rotatable connection between the upper clamp 1 and the lower clamp 2. A return spring is also provided between the upper clamp 1 and the lower clamp 2.

[0024] To achieve electrical connection, multiple wires 5 are provided between the upper clip 1 and the lower clip 2. These wires 5 are used to electrically connect the circuit boards or heating elements inside the upper clip 1 and the lower clip 2 to realize the normal heating function of the hair straightener. In addition, a power supply wire is connected to the rear end of the lower clip 2, which is also electrically connected to the upper clip 1 and the lower clip 2 through internal wires.

[0025] To avoid wire jamming, an upper housing cover 4 is provided on the inner side of the upper clamp 1. A guide portion 41 is integrally formed at the rear end of the upper housing cover 4. The guide portion 41 has an upward-opening C-shaped guide groove 411, and a front protruding edge 412 and a rear protruding edge 413 located on the front and rear sides of the guide groove 411, respectively. The guide groove 411 extends towards the rotating shaft 3 and spatially semi-encloses the rotating shaft 3.

[0026] The wire 5 is arranged as follows: the wire 5 starts from the lower clamp 2, passes around the rotating shaft 3 from the rear and upper sides of the guide part 41, and finally connects to the upper clamp 1. During this process, the wire 5 rests on the front protruding edge 412 and the rear protruding edge 413, thereby effectively isolating the wire 5 from the rotating shaft 3.

[0027] The main function of the guide groove 411 is to guide the shaft 3 to be smoothly inserted during assembly, ensuring that the shaft 3 can be smoothly positioned in the first shaft hole 111 and the second shaft hole 211. The front protrusion 412 and the rear protrusion 413 serve as isolation to prevent the wire 5 from directly contacting the shaft 3, thus preventing the wire from getting tangled or squeezed. With this structure, during assembly, the shaft 3 can be smoothly inserted along the guide groove 411 in the guide part 41, effectively avoiding the wire 5, thereby simplifying the assembly process, improving assembly efficiency, and minimizing potential problems caused by the wire 5 getting tangled or squeezed.

[0028] To further optimize the conductor protection effect, the height of the front convex side 412 is higher than that of the rear convex side 413, and the height of the front convex side 412 is higher than the highest point of the rotating shaft 3. This structure can more effectively prevent the conductor 5, which lies between the front convex side 412 and the rear convex side 413, from interfering with the rotating shaft 3.

[0029] To further ensure a safe distance between the conductor and the shaft, the distance L from the line connecting the tangents of the front convex edge 412 and the rear convex edge 413 to the center of the shaft 3 is greater than the radius R of the shaft 3. This design also effectively prevents interference between the conductor 5, which lies between the front convex edge 412 and the rear convex edge 413, and the shaft 3.

[0030] To prevent hard friction between the conductor 5 and the guide part 41, the edges of the front protrusion 412 and the rear protrusion 413 are rounded. This rounded corner design can effectively protect the insulation layer of the conductor 5 and extend the service life of the conductor.

[0031] To prevent the wire 5 from moving laterally, the two upper bearings 11 are located inside the two lower bearings 21, and the guide portion 41 is located between the two upper bearings 11. Furthermore, the gap between the outer sides of the guide portion 41 on both sides and the corresponding inner sides of the upper bearings 11 is smaller than the diameter of the wire 5. This structure effectively restricts the lateral movement of the wire 5 and prevents it from falling into the gaps on both sides of the guide portion 41.
