[0028] In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary, and not as a limitation. Therefore, other examples of exemplary embodiments can have different values.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0030] like Figures 1-6 As shown, this utility model embodiment provides a fingertip dart, the fingertip dart comprising:

[0031] The dart body 100 includes a spring device 150, a spring device limiting part 180, a tension spring, a blade rotating push rod 120, a push switch 110, a bearing seat 140, and a central rotating component 130. The spring device 150 is connected to the central rotating component 130 and is located inside the central rotating component 130. The tension spring is connected to the blade rotating push rod 120 and is used to pull the blade rotating push rod 120. The spring device limiting part 180 is connected to the central rotating component 130. The push switch 110 is connected to the bearing seat 140 and the spring device 150.

[0032] A telescopic blade 200, one end of which is movably connected to a blade rotation push rod 120. The blade rotation push rod 120 is used to push the telescopic blade 200, causing the telescopic blade 200 to open or retract.

[0033] When the spring device 150 moves downward, the spring device limiting part 180 disengages from the central rotating member 130. The central rotating member 130 then disengages from the limiting part 180 and, under the action of the tension spring, rotates, causing the telescopic blade 200 to unfold. When the telescopic blade 200 closes, the spring device limiting part 180 precisely engages the central rotating member 130, preventing it from rotating and ensuring the telescopic blade 200 remains in a stable retracted state.

[0034] Specifically, the extension and retraction process of the fingertip dart is as follows: First, press the push switch 110. The push switch 110 moves downward, causing the bearing seat 140 to also move downward. Under pressure, the press spring contracts, causing the spring device 150 to move downward. Second, the downward movement of the spring device 150 causes the spring device limiting part 180 to disengage from the central rotating part 130. Subsequently, under the action of the tension spring, the central rotating part 130 rotates. Finally, the central rotating part 130 drives the blade rotating push rod 120 to push the telescopic blade 200, causing the telescopic blade 200 to open. Preferably, a screw post is provided on the inner side of the base of the dart body 100. The press spring is sleeved on the screw post, the spring device 150 is assembled above the press spring, and the press spring device 150 is fixed to the screw post on the inner side of the dart base with a screw with a guide. Through the elastic force of the press spring and the action of the long guide rail around the screw post, the spring device 150 can maintain movement in one direction. Preferably, the dart body 100 is further provided with a central rotating member extension arm. When the telescopic blade 200 is in the open state, when the telescopic blade 200 is manually retracted, the telescopic blade 200 rotates, causing the central rotating member extension arm to rotate. When the telescopic blade 200 is closed, the spring device limiting part 180 just locks the central rotating member 130 in place. At the same time, the extension arms of the three spring devices 150 rise simultaneously, locking the telescopic blade 200 and the central rotating member, keeping the telescopic blade 200 in the retracted state.

[0035] This embodiment of the invention utilizes the cooperation of the spring device 150 and the central rotating component 130 to allow the telescopic blade 200 to quickly open and maintain stability, increasing the versatility of the dart. In the non-use state, the telescopic blade 200 is in a retracted state, avoiding the risk of accidental injury and improving the overall safety of the product. In this embodiment, the telescopic blade 200 can be retracted or opened, allowing users to retract or open it as needed, making the dart safer and more convenient to carry, effectively reducing space occupation and improving the portability of fingertip darts.

[0036] In an optional embodiment of this utility model, a central rotating component support rib 131 is provided inside the dart cover. The central rotating component support rib 131 is used to limit the central rotating component 130 by the squeezing force of the limiting ring on the face shell, so that the central rotating component 130 can only rotate left and right and cannot move up and down.

[0037] The upper cover assembly and the base assembly in the dart cover body can be tightly fitted together by fastening pins and screws. At the same time, the upper cover assembly can press the central rotating part support rib 131, so that the entire central rotating part 130 can only rotate left and right, but cannot move up and down.

[0038] In this embodiment of the invention, the tight integration of the upper cover assembly and the base assembly within the dart cover forms a protective barrier, effectively preventing external factors such as dust and moisture from damaging the internal components, thereby extending its service life. The design using a combination of fastening posts and screw posts ensures the fingertip dart has excellent reusability, allowing users to easily assemble and adjust it as needed. The upper cover assembly presses against the central rotating component support rib 131, ensuring that the entire central rotating component 130 can only rotate left and right, thus guaranteeing the stability of the fingertip dart during movement.

[0039] In an optional embodiment of this utility model, the dart body 100 is provided with a fixing position for the telescopic blade 200. The fixing position for the telescopic blade 200 is used to limit the telescopic blade 200 so that the telescopic blade 200 is fixed.

[0040] When the spring device 150 descends, the fixed locking position of the telescopic blade 200 disengages from the telescopic blade 200. The blade fixing position 160 uses the elastic force of the tension spring to pull the blade rotating push rod 120, which pushes the blade to rotate, thus realizing the opening function of the telescopic blade 200. When the spring device 150 rises, the blade fixing position 160 locks the telescopic blade 200 in place, so that the closed telescopic blade 200 will not spring open.

[0041] In this invention, the blade fixing slot 160 design allows the retractable blade 200 to be securely locked within the dart body 100 when the dart is not in use, preventing accidental injury due to misoperation. This locking slot provides necessary safety assurance for the user during use.

[0042] In an optional embodiment of this utility model, the dart body 100 is provided with a blade rotating column 170, which is used to limit the telescopic blade 200 so that the telescopic blade 200 moves around the blade rotating column 170 when it is in motion.

[0043] In this invention, the blade rotating column 170 effectively limits and supports the telescopic blade 200, enabling the telescopic blade 200 to move stably around the blade rotating column 170 during operation. The user only needs to press the telescopic blade 200 to retract it in the original direction. The blade rotating column 170 can restrict the movement trajectory of the telescopic blade 200, ensuring that the telescopic blade 200 does not deviate from the retraction path, thereby improving the performance and safety of the fingertip dart.

[0044] In an optional embodiment of this utility model, the dart body 100 is provided with a push-button switch freewheel bearing 111, the push-button switch freewheel bearing 111 is fixed on the bearing seat 140, and the push-button switch 110 is connected to the push-button switch freewheel bearing 111.

[0045] The push-button switch freewheel bearing 111 is fixed on the bearing housing 140. The bearing housing 140 assembly is placed in the groove of the bearing housing 140. The screw post of the push-button switch 110 passes through the hole of the top cover assembly on the dart and then through the inner diameter of the switch freewheel bearing 111 on the bearing housing 140 assembly. The top cover assembly is used to firmly fix the push-button switch 110 and the bearing housing 140 assembly together. At the same time, the top cover assembly, the bearing housing 140 assembly and the push-button switch 110 are firmly assembled together to form a new dart top cover assembly.

[0046] In this embodiment of the invention, the organization and fixation of the push-button idling bearing 111 and the bearing seat 140 not only improves the performance of the dart and enhances the user's control experience, but also demonstrates the wide application potential of this design. Whether in entertainment, education, or research applications, this novel dart top cover assembly can provide users with a better user experience.

[0047] In an optional embodiment of the present invention, a handle base 190 and a dart handle 195 are provided on the bottom side of the dart body 100. The handle base 190 is connected to the bottom of the dart body 100, and the dart handle 195 is connected to the handle base 190 by an inverted buckle structure.

[0048] The grip 190 and dart handle 195 refer to a structure designed at the bottom of the dart body 100. The dart handle 195 is used to improve the stability and comfort of the user's grip, allowing for a firm hold and preventing slippage when handling the dart. The dart handle 195 can be made of silicone, rubber, or other materials with a high coefficient of friction. These materials provide a good grip in both dry and wet environments. Anti-slip materials can also be applied to specific areas of the dart handle 195 surface, such as by adding surface texture or patterns to increase friction and prevent the dart from slipping out of the fingers.

[0049] Preferably, the handle base 190 is also provided with a handle free-spinning bearing, which is fixed on the outer surface of the dart body 100. The long screw post of the dart base passes through the inner diameter of the handle free-spinning bearing. The long screw post of the handle base 190 passes through the handle free-spinning bearing and is fixed together with the screw post on the dart base that passes through the handle free-spinning shaft with a screw with a mortise, so that the handle base 190 can rotate when the handle is manually turned. The user can wear the dart handle 195 on his hand to rotate the entire fingertip dart, so that the entire product can rotate in the hand.

[0050] In this embodiment of the invention, the design of the dart handle 195 and the grip base 190 improves the stability and comfort of the user when using fingertip darts. This improvement effectively prevents the fingertip dart from slipping off the fingertip, fully meeting the user's needs in various operating scenarios.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
