[0013] Appendix Figure 1 This is a schematic diagram of the structure of this utility model; Appendix Figure 2 For the appendix Figure 1 Structural breakdown diagram. Detailed Implementation

[0014] 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.

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] This utility model provides the following technical solution: As attached Figure 1-2 As shown, this utility model discloses a handle for holding keys, including a handle body 1 and a handle cover 2. The handle body 1 has a handle portion 3 and a transmission portion 4. A key placement groove 5 is formed recessed on the end face of the handle portion 3 away from the transmission portion 4. A key (not shown) is placed in the key placement groove 5. A key positioning structure 6 is provided in the key placement groove 5 to position the key in the key placement groove 5. The handle cover 2 is flip-mounted on the handle portion 3 to seal and cover the key placement groove 5. Specifically, in this design, by providing a key placement groove 5 in the handle portion 3 of the handle body 1 and equipping it with a key positioning structure 6, it is possible to ensure that the key is stable and does not wobble in the placement groove, avoiding noise or damage to the key caused by key movement. Meanwhile, the flip-up handle cover 2 design not only makes it convenient for users to quickly take out and put away the key, but also seals and covers the key placement slot 5 when the key is not in use, effectively preventing external factors such as dust and moisture from corroding the key and the inside of the handle, thereby extending the service life of the key and the handle and improving the overall quality of the product and the user experience.

[0017] Furthermore, the key positioning structure 6 is a protruding rib formed within the key placement groove 5. The rib includes a handle rib 7 and a head rib 8. A handle positioning groove 9 and a head positioning groove 10 are respectively recessed on the handle rib 7 and the head rib 8. Both ends of the key extend into the handle positioning groove 9 and the head positioning groove 10, respectively, and connect with the corresponding ribs. Specifically, in this embodiment, the handle rib 7 and the head rib 8 provide a precise positioning point for the key within the placement groove. The dimensions of the handle positioning groove 9 and the head positioning groove 10 match the two ends of the key. When the key is inserted, the handle portion fits precisely into the handle positioning groove 9, while the head portion fits into the head positioning groove 10. This design not only ensures the stability of the key within the placement groove, preventing the key from shaking and shifting during use, but also significantly reduces noise caused by the key colliding with the handle's interior, and avoids wear or damage to the key due to prolonged shaking. Furthermore, this positioning structure is simple and effective, requiring no additional fixing devices, which reduces production costs and improves product reliability and durability.

[0018] Furthermore, the key handle rib 7 has a circular rib 11 at its center, and a key magnetic groove 12 is formed on the circular rib 11. A magnet (not shown) is placed inside the key magnetic groove 12, and the magnet is adhered and fixed to the inner wall of the key magnetic groove 12. Specifically, in this embodiment, the circular rib 11 and the magnet inside the key magnetic groove 12 provide additional magnetic attraction for key positioning. When the key is placed in the key placement slot 5 and embedded in the handle positioning slot 9 and the head positioning slot 10, the magnet attracts the key, making it more firmly fixed in the placement slot. This magnetic design not only enhances the stability of the key and prevents it from accidentally falling off during use, but also further reduces noise and wear caused by key shaking. At the same time, the way the magnet is adhered and fixed to the inner wall of the key magnetic groove 12 ensures the stability of the magnet and avoids the magnet falling off or shifting during use, thereby ensuring the durability and reliability of the magnetic attraction effect.

[0019] Furthermore, at least two spaced-apart handle rotating ends 13 protrude from one side of the key placement slot 5 and are located on the same horizontal line. Corresponding to the handle rotating ends 13, a cover rotating end 14 protrudes from the handle cover 2. Both the cover rotating end 14 and the handle rotating end 13 have corresponding rotating holes and are rotatably connected by a rotating shaft. Specifically, in this embodiment, the arrangement of the handle rotating end 13 and the cover rotating end 14 provides a stable support structure for the flipping of the handle cover 2. The at least two spaced-apart handle rotating ends 13 located on the same horizontal line ensure the balance of the handle cover 2 during the flipping process, avoiding shaking or jamming caused by single-point support. Simultaneously, the corresponding rotating holes on both the cover rotating end 14 and the handle rotating end 13, and their rotatable connection by a rotating shaft, make the flipping of the handle cover 2 smoother, allowing users to easily open or close the handle cover 2 for convenient key access.

[0020] Furthermore, the key placement slot 5 has a side slot wall 15 and a bottom slot wall 16. A cover adsorption end 17 protrudes from the bottom slot wall 16 of the key placement slot 5. A cover magnetic groove 18 is formed on the cover adsorption end 17, and a cover magnetic element (a magnet) is attached inside the cover magnetic groove 18. The cover magnetic element magnetically attracts the handle cover 2 when it is closed. Specifically, in this embodiment, the cover adsorption end 17 and the cover magnetic element provide additional magnetic attraction for closing the handle cover 2. When the handle cover 2 is flipped to the closed state, the cover magnetic element magnetically attracts the handle cover 2, causing the handle cover 2 to fit tightly against the key placement slot 5. This magnetic fixing method not only enhances the sealing of the handle cover 2, effectively preventing dust, moisture, and other external factors from entering the key placement slot 5, but also prevents the handle cover 2 from opening due to accidental collisions during use, thereby further protecting the cleanliness and safety of the key and the handle's interior. Meanwhile, the adhesive fixing method between the magnetic clasp of the cover and the inner wall of the magnetic groove 18 of the cover ensures the stability of the magnetic clasp of the cover and prevents it from falling off or shifting during use, thereby ensuring the durability and reliability of the magnetic attraction effect.

[0021] Furthermore, several reinforcing guide ends 19 protrude from the side groove wall 15. A guide inclined surface 20 is provided at the end of each reinforcing guide end 19 near the opening of the key placement slot 5. During the closing process, the handle cover 2 enters the key placement slot 5 along the guide inclined surface 20. Specifically, in this embodiment, the setting of the reinforcing guide ends 19 and the design of the guide inclined surface 20 provide precise guidance for the closing process of the handle cover 2. When the handle cover 2 begins to close, its edge first contacts the guide inclined surface 20 on the reinforcing guide end 19. This inclined surface guides the handle cover 2 at a suitable angle, allowing it to smoothly and steadily enter the key placement slot 5 along a predetermined trajectory. This design not only avoids the handle cover 2 colliding with or getting stuck on the side groove wall 15 due to positional deviation during the closing process, but also greatly improves the accuracy and efficiency of the handle cover 2's closing. The user only needs to gently push the handle cover 2, and it can smoothly slide into the key placement slot 5 along the guide inclined surface 20 and magnetically attract with the cover's magnetic components, achieving a tight closure. Meanwhile, the protruding design of the reinforced guide end 19 also enhances the structural strength of the side groove wall 15, improving the overall durability and reliability of the handle.

[0022] Furthermore, a key transmission component 21 is provided inside the transmission part 4, and a key transmission hole 22 communicating with the interior of the transmission part 4 is opened on the groove wall of the key placement groove 5. One end of the key transmission component 21 extends into the key transmission hole 22 and connects with the handle part 3. Specifically, in this embodiment, the structural design of opening a key transmission hole 22 communicating with the interior of the transmission part 4 on the groove wall of the key placement groove 5, and having one end of the key transmission component 21 extend into the key transmission hole 22 and connect with the handle part 3, can cover the keyhole on the key transmission component 21 with the handle cover 2. While ensuring a simple appearance, it effectively prevents dust, debris, etc. from entering the interior of the transmission part 4 through the keyhole, thereby avoiding problems such as transmission failure or component damage caused by foreign object intrusion.
