Description

Technical Field

[0001] This utility model relates to the field of fidget spinner toys, and in particular to a split-type fidget spinner. Background Technology

[0002] Fidget spinners are a type of toy, commonly made of plastic or metal. Currently, high-end fidget spinners feature a single, machined metal rotating part. For example, in August 2025, the "Arrogant Old Blacksmith" shop on Taobao sold a noisy fidget spinner consisting of a rotating part, bearings, and a locking mechanism; its rotating part was a single, four-bladed unit. On Bilibili, a video titled "Want to Try a Foldable Fidget Spinner?" uploaded on October 24, 2024, by the author "Rational NINI," showcased over ten different fidget spinners, all with a single, integrated rotating part.

[0003] One type of fidget spinner is the open-armor spinner. Besides the spinning main body, it has an open-armor section mounted on it. When the spinner spins, the open-armor section moves due to centrifugal force, producing more sound, light, and force feedback effects. For example, the Garlic QS tuning fork-type open-armor spinner sold by the Zhiwanwu store on Taobao in August 2025 has a three-bladed integrated rotating main body, with open-armor blades added to this base. On Bilibili, a video titled "First Challenge with a Gear-Linked Open-Armor Spinner?! Phantom Refinement EDC's New Product 'Explosion,' Full Disassembly and Review!" was uploaded by author Ryan EDC on July 10, 2024. The article showcases a spinning top called "Explosion," whose complex peripheral structure requires individual processing and assembly before being screwed onto the main spinning body. The assembly method lacks a single blade fixing device for easy disassembly and reassembly of all the blades, making it unsuitable for general consumers to disassemble and modify. Furthermore, the separately installed parts are functional extension components, providing additional play options such as opening the shell and twisting, and do not fall under the conventional definition of spinning top blades. In August 2025, the "Baby Joy Toys" store on Pinduoduo sold a pure copper metal colorful fidget spinner. Its main body featured multiple threaded cylinders that could be disassembled, but the connection method was not secure. Different screwing forces resulted in varying depths of connection between the cylinders, leading to different dynamic balances. Users found it difficult to adjust the balance, and the screwed parts were prone to loosening during use, causing the spinner's dynamic balance to constantly change. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a fidget spinner that is easy and reliable to assemble and disassemble, can maintain dynamic balance continuously, has lower production and usage costs, more combinations, and higher playability.

[0005] The technical solution to achieve the purpose of this utility model is to provide a split-type fidget spinner, including a body and at least two blades, the blades being detachably connected to the circumference of the body, and all blades being dynamically balanced; The base plate of the main body has multiple blade connecting grooves at regular intervals along its edge; the inner end of the blade has a mounting part, and the blade is mounted on the main body by connecting the mounting part to the corresponding blade connecting groove.

[0006] Furthermore, the aforementioned split-type fidget spinner also includes a blade limiting plate; the blade connecting groove is a T-shaped groove that opens outward and upward, and a blade limiting part is provided around the upper edge of the bottom plate of the main body, and the blade limiting part is connected to the middle of two adjacent blade connecting grooves; the blade mounting part corresponds to the T-shaped groove of the blade connecting groove and forms a T-shape; the blade is inserted into the blade connecting groove of the main body through its mounting part; the blade limiting plate is detachably installed on the blade limiting part from the front to limit the front and rear of the blade.

[0007] Furthermore, the blade connection slots are set at 0 degrees and 180 degrees, and the number of blades is 2.

[0008] Furthermore, the blade connection slots are set at 0 degrees, 90 degrees, 180 degrees, and 270 degrees, and the number of blades is 2 or 4.

[0009] Furthermore, the blade connection slots are set at 0 degrees, 60 degrees, 120 degrees, 180 degrees, 240 degrees, and 300 degrees, and the number of blades is 2, 3, or 6.

[0010] Furthermore, the blade connection slots are set at 0 degrees, 60 degrees, 90 degrees, 120 degrees, 180 degrees, 240 degrees, 270 degrees, and 300 degrees, and the number of blades is 2, 3, 4, or 6.

[0011] Furthermore, the blade connection slots are set at 0 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 135 degrees, 180 degrees, 225 degrees, 240 degrees, 270 degrees, 300 degrees, and 315 degrees, and the number of blades is 2, 3, 4, 6, or 8.

[0012] Furthermore, the base plate of the main body is set as a disc; the blade limiting part is annular; the blade limiting part is provided with internal thread; the blade limiting disk is annular, the size of the blade limiting disk corresponds to the blade limiting part, the rear end face of the blade limiting disk is provided with a neck, the neck is provided with an external thread corresponding to the internal thread of the blade limiting part; the blade limiting disk is screwed into the blade limiting part of the main body from the front through a bayonet to limit the front and rear of the blade.

[0013] Furthermore, the front end face of the blade limiting disc is provided with a bayonet for rotating installation or removal.

[0014] Furthermore, the aforementioned split-type fidget spinner also includes a bearing and a locking mechanism; the main body has a through bearing hole in the center; the size of the bearing corresponds to the bearing hole of the main body, and the thickness corresponds to the base plate of the main body; the bearing has a central through hole; the bearing is inserted into the bearing hole of the main body through an interference fit; the locking mechanism includes a detachable upper locking mechanism and a lower locking mechanism connected front and back, the size of the cover plate of the locking mechanism corresponds to the base plate of the main body; the lower locking mechanism passes through the bearing in the center and is tightly connected to the upper locking mechanism to seal the main body.

[0015] This utility model has the following positive effects: (1) The split-type fidget spinner of this utility model can reduce production and inventory costs. Compared with the previous one-piece fidget spinner, if you want to produce a series of 2-blade, 3-blade, 4-blade, 6-blade, and 8-blade fidget spinners with the same blade shape, you need to produce the spinning bodies of various types of 2-blade, 3-blade, 4-blade, 6-blade, and 8-blade spinners separately, develop multiple CNC machining programs, and set up multiple inventories, thereby increasing production costs and inventory funds. This utility model adopts a split-type fidget spinner design, which only requires the production of one type of spinner body and one type of spinner blade. There is no need to develop multiple CNC machining programs or set up multiple inventories. Different numbers of spinner blades can be shipped according to the user's selection.

[0016] (2) The split-type fidget spinner of this utility model can reduce maintenance costs. Since the main body of the fidget spinner accounts for most of the cost, if a one-piece fidget spinner is broken, causing dynamic imbalance or damage to the hand, the entire main body needs to be replaced for repair, which is very costly. Since when a fidget spinner falls, it is usually damaged when a blade hits the ground at its sharp point. With a split-type fidget spinner, only the damaged blade needs to be replaced to repair the spinner, which greatly reduces maintenance costs.

[0017] (3) The split-type fidget spinner of this utility model can increase the playability of the spinner. Spinners with different numbers of blades can bring different user experiences. If the traditional one-piece spinner design is adopted, users need to spend money to buy multiple fidget spinners. With the split-type spinner design, users can easily change the blades. They only need to buy one spinner to experience a variety of sound, light and shadow and force feedback effects, which increases the playability of the spinner without spending more money.

[0018] (4) The modular fidget spinner of this invention offers a richer variety of spinner combinations. In a one-piece spinner, the entire rotating body undergoes a single surface treatment, resulting in a relatively uniform appearance. With a modular design, each spinner blade can be individually surface-treated. Furthermore, spinner blades with different appearances can be grouped according to their dynamic balance characteristics, and blades with the same dynamic balance characteristics but different appearances can be mixed and matched. This results in a richer variety of spinner combinations, allowing for more diverse sound, light, and force feedback effects both at rest and during rotation.

[0019] (5) The dynamic balance performance of the split-type fidget spinner of this utility model is easier to ensure. The limiting accuracy of the spinner blade is mainly determined by the machining accuracy of the parts. The user's operation will not have too much impact on the dynamic balance performance.

[0020] (6) The individual spinner blades of the split-type fidget spinner of this utility model can also be used as ornaments or pendants, which increases the utilization rate. Attached Figure Description
