[0026] 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.

[0027] This utility model provides a folding key puller as shown in Figures 1-5. It is ingeniously designed, has a unique structure and function, and is suitable for a variety of scenarios.

[0028] A folding key puller includes a key pull cap body 1 and a key pull body 2 rotatably arranged relative to each other. The key pull cap body 1 is provided with a fixed ring 11, and the key pull body 2 is provided with a moving ring 21. The fixed ring 11 and the moving ring 21 are rotatably arranged to allow the key pull cap body 1 and the key pull body 2 to rotate. When the key pull body 2 rotates, the fixed ring 11 remains stationary, and the moving ring 21 rotates with the key pull body 2.

[0029] Furthermore, the keycap puller body 1 is provided with a pair of first elastic clamping arms 12, and the switch puller body 2 is provided with a pair of second elastic clamping arms 23. When the second elastic clamping arms 23 are wrapped by the first elastic clamping arms 12 on both sides, that is, the first elastic clamping arms 12 and the second elastic clamping arms 23 are on the same side, forming a four-legged tripod posture, the switch puller body 2 and the keycap puller body 1 are in a folded state. When the second elastic clamping arms 23 rotate away from the first elastic clamping arms 12, the switch puller body 2 and the keycap puller body 1 are in the use state. The second elastic clamping arms 23 rotate 90 degrees or 180 degrees with the moving ring 21, providing the best user experience.

[0030] To prevent rotation of the keycap puller body 1 and the keyshaft puller body 2, the inner wall of the fixed ring 11 is provided with ribs 111, and the outer wall of the moving ring 21 is provided with a groove 211 that matches the ribs 111. The ribs 111 are engaged in the groove 211. The ribs 111 on the inner wall of the fixed ring 11 and the groove 211 on the moving ring 21 cooperate with each other, which not only prevents rotation between the keycap puller body 1 and the keyshaft puller body 2, but also produces a distinct tactile feedback.

[0031] To facilitate the disassembly of the keycap puller body 2 and the keycap puller body 1, a cover plate 22 is provided on the moving ring 21. A second elastic clamping arm 23 is located on the outer surface of the cover plate 22, and a snap-fit ​​assembly 25 is provided between the two cover plates 22. The snap-fit ​​assembly 25 is located on the inner side of the moving ring 21. The two cover plates 22 are assembled on both sides of the fixed ring 11 through the snap-fit ​​assembly 25 without affecting the rotation of the moving ring 21 within the fixed ring 11. This not only ensures the stable installation of the snap-fit ​​assembly 25, but also allows the second elastic clamping arm 23 to drive the cover plate 22, causing the moving ring 21 to rotate on the inner wall of the fixed ring when the user adjusts the keycap puller body 2.

[0032] Specifically, a pair of first elastic clamping arms 12 extend downwards symmetrically along the outer periphery of the fixed ring 11. The two ends of the fixed ring 11 are tightly inserted into the cover plate 22. A pair of moving rings 21 are respectively disposed on the inner surface of the cover plate 22. A snap-fit ​​assembly 25 is installed on the opposite inner surface of the cover plate 22, and the snap-fit ​​assembly 25 is located inside the moving ring 21. A second elastic clamping arm 23 extends downwards from the outer surface of the cover plate 22, and a metal hook 24 is fitted at the end of the second elastic clamping arm 23 away from the snap-fit ​​assembly 25.

[0033] From an ergonomic perspective, both the first elastic clamp arm 12 and the second elastic clamp arm 23 are designed with irregular shapes, which greatly enhances the user's grip comfort and anti-slip performance. At the same time, the offset arrangement between the keycap puller body 2 and the keycap puller body 1 provides convenient conditions for the rotation and folding of the keycap puller.

[0034] During installation, the snap-fit ​​assembly 25 with the keycap puller body 2 is inserted into the fixed ring 11 via the port of the fixed ring 11, thereby allowing the moving ring 21 of the keycap puller body 2 to be precisely installed onto the fixed ring 11. Subsequently, the first elastic clamping arm 12 and the second elastic clamping arm 23 of the keycap puller body 1 and the keycap puller body 2 form a staggered arrangement, which not only gives the keycap puller a folding function but also allows it to be adjusted to any angle. This design makes the product lighter and easier to carry and store.

[0035] Furthermore, the snap-fit ​​assembly 25 includes a socket 251 and a plug 252. The socket 251 is fixed to the inner side of one of the cover plates 22, and the plug 252 is fixed to the inner side of the other cover plate 22, with their positions symmetrical. Additionally, a latch 253 and a latch 254 are provided. The latch 254 is mounted on the same cover plate 22 as the plug 252, and the latch 253 is mounted on the same cover plate 22 as the socket 251. Through the coordinated cooperation of the socket 251 and the plug 252, a preliminary snap-fit ​​between the two cover plates 22 and the fixed ring 11 can be achieved in advance. Subsequently, with the cooperation of the latch 253 and the latch 254, the two cover plates 22 cover both sides of the fixed ring 11. In this way, the fixed ring and the cover plates 22 can be adjusted at any angle, adapting to different operating scenarios, improving the flexibility and applicability of the tool, and facilitating the folding operation of the key puller. To make the installation process smoother, the inner edge of the socket 251 slot is designed with a beveled surface to facilitate the insertion of the plug 252; the corner of the buckle 253 is chamfered at one end to effectively avoid collision with other structural components.

[0036] In terms of storage and portability design, a key ring 3 is fixedly connected to the center of the top of the ring 11, and the key ring 3 has a hanging hole 31. This hanging hole 31 makes it easy to connect to a key, so that the key puller can be hung or strung together with the key, effectively improving the convenience of product storage and portability.

[0037] In actual use, first insert the snap-fit ​​assembly 25 with the pull-off body 2 into the fixed ring 11, ensuring that the socket 251 and the insert block 252, and the buckle 253 and the snap block 254 are accurately engaged, thus completing the installation of the two cover plates 22 on the fixed ring 11. When the pull-off function is needed, use the metal hook 24 to clamp the shaft part to be removed, and then pull it out; if the keycap removal function is needed, align the first elastic clamping arm 12 with the keycap to be removed, ensure the contact surface is stable, and then pull it out. After the operation is completed, take advantage of the misalignment between the pull-off body 2 and the keycap removal body 1 to rotate the pull-off body 2 on the fixed ring 11, thus folding the pull-off and keycap puller. Moreover, the angle can be adjusted at will according to actual needs throughout the use. In summary, this foldable pull-off and keycap puller achieves the flexibility of angle adjustment and folding function, effectively reducing the space occupied, and the design of the hanging hole 31 greatly facilitates storage and carrying.

[0038] This invention combines a keycap puller and a switch puller into one tool, making it more convenient to carry and easier to find, reducing the time spent gathering tools during use. Because both the switch puller and keycap puller bodies can be folded / rotated, the overall size is smaller and easier to store. Furthermore, when not in use for a short period, the folded switch puller and keycap puller bodies can stand upright on the desktop via two pairs of spring arms, improving desktop tidiness and ease of access, thus enhancing the practicality of the switch puller and keycap puller. In addition, the switch puller and keycap puller can be disassembled and separated via a snap-fit ​​assembly.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
