[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] like Figure 1 and Figure 2 As shown, a magnetic mobile phone pull-up back clip includes a protective shell 1, a magnetic ring 2 embedded below the protective shell 1, and a pair of adjusting rods 3 that penetrate the protective shell 1 and are centrally symmetrically distributed. Each adjusting rod 3 consists of a gear rod 8 and a limiting rod 9. The gear rod 8 meshes with an adjusting gear 6, which is located at the center inside the protective shell 1 and connected to torsion springs 7 at both ends. An arc-shaped plate 4 is provided at one of the opposite ends of the adjusting rods 3. A protective pad 5 is embedded inside the arc-shaped plate 4, with an arc angle of 90-150° to facilitate a close fit to the mobile phone.

[0017] In this implementation, the components work together to achieve a stable grip and convenient adsorption of the mobile phone. A magnetic ring 2 is embedded below the protective shell 1, allowing the back clip to adhere to ferrous or magnetic surfaces, giving the device mobility and versatility. An adjusting rod 3 passes through the protective shell 1, where a gear rod 8 meshes with an adjusting gear 6. The adjusting gear 6 automatically resets and rotates under the action of a torsion spring 7, enabling flexible adjustment of the adjusting rod 3 to accommodate mobile phones of different sizes. An arc-shaped plate 4 is located at the far end of the adjusting rod 3, with a protective pad 5 embedded inside to protect the phone's frame and prevent damage during gripping. The arc of the arc plate 4 is designed with an arc of 90-150°, allowing for better fit to the phone and improving gripping stability. Through the ingenious combination of these components, this device solves the problems of immobility, poor versatility, and easy damage to the phone's frame in existing mobile phone magnetic devices. A contact pad 14 for contacting the phone is also engaged above the protective shell 1.

[0018] like Figure 3 and Figure 4 As shown, the adjusting rod 3 has slots 12 on both sides near the arc-shaped edge 4 to facilitate the stretching of the adjusting rod 3. The limiting plate 10 connected to one end of the gear rod 8, the gear rod 8, and the arc-shaped plate 4 together form a groove 11 corresponding to the adjusting gear 6. The adjusting gear 6 is connected to the protective shell 1 through the fixed shaft 13. One end of the torsion spring 7 is fixedly connected to the fixed shaft 13, and the other end is fixedly connected to the protective shell 1, ensuring that the adjusting gear 6 can return to its original rotation after rotation, thereby achieving stable adjustment of the adjusting rod 3.

[0019] In this embodiment, the device also involves the mobile phone itself and external magnetic fixing devices during use. The mobile phone needs to have metal parts that can be attracted by magnets, such as the magnetic metal frame or back cover that comes with some mobile phones, or magnetic metal patches that can be added by the user. External magnetic fixing devices include common magnetic accessories such as car magnetic brackets and desktop magnetic bases. These devices all have magnets or iron parts inside that match the magnetic ring 2 of this device to achieve stable attraction. In terms of materials, the protective shell 1 of this device can be made of lightweight and sturdy plastic material, such as polycarbonate PC or ABS plastic, to ensure that the device is lightweight while having a certain strength. The metal parts such as the adjustment rod 3 and gear rod 8 can be made of stainless steel, which combines strength and corrosion resistance to ensure stable performance over long-term use. The protective pad 5 is made of soft silicone material, which can effectively protect the mobile phone frame and has good elasticity, increasing the friction during clamping and preventing the mobile phone from slipping.

[0020] It is worth noting that the transmitter magnet of this device offers significant advantages during use. It generates a strong magnetic field, achieving a stable and secure attachment to the transmitter magnet. The strong and stable adhesion ensures the phone clip is unlikely to fall off during use, effectively preventing damage from drops due to insufficient adhesion. Furthermore, the transmitter magnet design is compatible with various magnetic accessories on the market, such as car magnetic holders and desktop magnetic bases, providing users with a highly versatile phone securing solution.

[0021] When using the device, first select the desired location for the magnetic phone clip, generally a surface made of iron or a magnet. Then, align the magnetic ring of the device with the target location, gently attach it, and ensure a secure fit. Next, depending on the width and thickness of the phone, pull the adjusting rods on both sides outwards to adjust the distance between the curved plates to match the phone's dimensions. Place the phone between the curved plates and release the adjusting rods; the springs will clamp the phone in place. Simultaneously, the protective pads on the inner side of the curved plates will protect the phone's frame from damage. Finally, attach the device with the phone in place to the desired location, such as a car magnetic holder or a desktop magnetic base, to secure and display the phone. After use, remove the device from its attachment position and then remove the phone from between the curved plates.

[0022] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
