[0024] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances. In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] The utility model provides a kind of iron wire gyro launching device, to make a simple and feasible iron wire gyro launching device using simple and easy to obtain device, such as Figure 1 andFigure 2 As shown, the device includes a driving device and a gyro clamp, the gyro clamp including a fixed disc 1 and a plurality of elastic claws 2, the plurality of elastic claws 2 being evenly fixed and connected circumferentially on the fixed disc 1; the elastic claws 2 adopt common bamboo products such as disposable chopsticks as materials. The plurality of elastic claws 2 fixed disc 1 is fixed on the driving device, and the fixed disc 1 adopts a conventional hard disc-shaped building block. The device realizes efficient launching of the wire gyro through the synergistic effect of the driving device and the gyro clamp. The gyro clamp is composed of a fixed disc 1 and a plurality of circumferentially evenly distributed elastic claws 2, which firmly hold the wire gyro through their elastic deformation performance. When clamping, the wire gyro is placed between the claws and keeps concentric with the fixed disc 1, so that it maintains stability and symmetry during rotation, avoiding shaking caused by eccentricity or uneven clamping. The distribution of the claws ensures the uniform stress of the clamp, providing a guarantee for the stability of the gyro start. The driving device directly realizes high-speed driving of the gyro by driving the fixed disc 1 to rotate axially. With the increase of the rotating speed, the claws gradually expand outward under the action of centrifugal force, and this dynamic expansion process ensures that the clamping force is gradually released, and when the rotating speed reaches a certain value, the wire gyro is accurately released from the claws and realizes smooth launching. The whole launching process utilizes the elastic deformation characteristics and centrifugal characteristics of the claws, and efficiently completes the dynamic conversion from fixation to release through a simplified mechanical structure. This design not only reduces the demand for complex components, but also improves the practicality and reliability of the device. The rigidity of the fixed disc 1 and the elasticity of the claws form a good complementary relationship in the device. Through the support of the fixed disc 1 and the flexible clamping of the claws, the device can not only adapt to wire gyros of various sizes, but also effectively maintain the central symmetry of the gyro during launching. The process of centrifugal expansion of the claws makes the instant when the gyro is released from the clamp have clear directionality and speed characteristics, ensuring the efficiency and stability of the gyro launching. When in use, the user only needs to place the wire gyro in the clamp and start the driving device to realize launching. The overall design is simple and intuitive, and has good performance, providing a simple and reliable solution for the competitive activities and scientific practice of wire gyros.

[0026] In the preferred embodiment, the elastic claws 2 have six, which are evenly fixed on the fixed disc 1. The fixed mode of the claws is hot melt glue. The six elastic claws 2 are evenly fixed on the fixed disc 1, which ensures the symmetry and balance of the structure. The evenly distributed claws can firmly fix the wire gyro in a multi-point clamping manner, effectively avoiding the eccentricity and shaking during rotation caused by uneven distribution of clamping points, thereby ensuring the stability of the gyro during starting and launching. The hot melt glue method is used to fix the claws, which further improves the firmness and reliability of the structure. The hot melt glue can form a strong bond between the claws and the fixed disc 1, and the hot melt glue also has a certain elasticity, so that the elastic claws 2 have an inward pressure when clamping the wire gyro, and can still remain stable under high-strength rotation and stress, so that the wire gyro is not easy to loosen or shift. Through this design of claw structure and fixing method, the clamp not only can stably clamp the wire gyro, but also can uniformly transmit the rotary torque when the fixed disc 1 is rotated by the driving device, so that the gyro obtains the initial rotational speed with higher efficiency. Finally, the claws expand outward under the action of centrifugal force, realizing the precise release and smooth launching of the gyro, and laying a solid foundation for the improvement of the overall performance of the device.

[0027] In the preferred embodiment, the gyro clamp increases the design of the adjusting rope 3, which is wrapped around the multiple elastic claws 2. The distance between the elastic claws 2 can be adjusted by moving up and down or changing the tightness of the wrapping. This design makes the device more flexible when clamping wire gyros of different sizes. Users can adjust the size of the clamping area by adjusting the tightness of the adjusting rope 3 according to the size of the wire gyro, ensuring that the gyro can be stably clamped in the elastic claws 2, even the smaller size wire gyro can be accurately fitted. The contraction and mobility of the adjusting rope 3 not only improves the adaptability of the device, but also increases the convenience of operation. During the adjustment of the claw spacing, the adjusting rope 3 can quickly respond to the demand, allowing users to quickly complete the adjustment without replacing the claws or reinstalling the structure. At the same time, by adjusting the adjusting rope, the same wire gyro can be released at different rotational speeds. Specifically, when the adjusting rope is tightened (or the whole is moved down a bit), the wire gyro will be released at a higher rotational speed; when the adjusting rope is loosened (or the whole is moved up a bit), the wire gyro will be released at a lower rotational speed.

[0028] In a preferred embodiment, the design of the driving device achieves efficient, stable and easy-to-operate power transmission through a precise transmission structure and support system. The driving device mainly consists of a fixed support rod, a first transmission rod 7, a first transmission gear 8, a second transmission rod 9, a second transmission gear 10, a third transmission gear 11, a fourth transmission gear 13 and a third transmission rod 12. These components work together to transmit power through the meshing of gears and the rotation of rod members, ensuring that the gyro launching device can operate smoothly. In this design, the meshing between the first transmission gear 8 and the second transmission gear 10 and the meshing between the third transmission gear 11 and the fourth transmission gear 13 form a multi-stage transmission system. This multi-stage gear transmission design allows the device to more accurately control the rotational speed of the fixed disc 1 and gradually increase the speed, ensuring that the gyro can rotate quickly and stably during launching. When the operator turns the rotating handle, power is transmitted to the first transmission rod 7 through the rotating handle, and then gradually transmitted to the gyro clamp through the transmission gears, ensuring accurate operation control. The first transmission rod 7, the second transmission rod 9 and the third transmission rod 12 are all rotationally arranged on the fixed support rod. This arrangement not only allows the transmission components to rotate smoothly, reducing friction and wear, but also ensures the stability and durability of the entire transmission system. The design of the fixed support rod uses a combination of an upper fixed support rod 4, a lower fixed support rod 5 and a connecting piece 6. The connecting piece 6 is fixed at both ends of the upper fixed support rod 4 and the lower fixed support rod 5, away from the end of the first transmission rod 7, making the entire support structure more solid and avoiding instability caused by external forces or vibrations. Through this structural design, the transmission system maintains balance during operation and achieves efficient power transmission, while ensuring smooth cooperation between components and reducing energy loss, improving the working efficiency of the device. The meshing precision between the first transmission gear 8 and the second transmission gear 10, and the third transmission gear 11 and the fourth transmission gear 13 is high, allowing the device to maintain low vibration and noise, thereby improving the comfort during use. The driving device also includes a rotating handle, which further optimizes the convenience of operation. The rotating handle is connected to the first transmission rod 7 through a connecting rod 14, and the grip 15 is fixed to the upper side of the connecting rod 14 away from the first transmission rod 7. Through the grip 15, the operator can easily control the rotation of the handle, thereby adjusting the rotation speed of the wire gyro. The design of the rotating handle makes the operation more intuitive and convenient for users to make precise adjustments. In summary, the driving device, through the careful design of the multi-stage gear transmission system, the solid support structure and the convenient handle operation, not only improves the stability and efficiency of the gyro launching device, but also ensures the durability after long-term use. The reasonable matching and structural design of the multi-stage gears allow the device to adapt to different specifications of wire gyros, while avoiding mechanical impact caused by high speed, providing an efficient, stable and easy-to-operate solution for users.

[0029] In the preferred embodiment, the transmission ratio between the first transmission gear 8 and the second transmission gear 10 is 5:1, and the transmission ratio between the third transmission gear 11 and the fourth transmission gear 13 is also 5:1. Such a transmission ratio configuration makes the entire drive system have a significant speed-up effect. Specifically, when the operator rotates the rotating handle, the power is transmitted to the first transmission gear 8 through the first transmission rod 7, and through the meshing with the second transmission gear 10, the rotation speed of the first transmission rod 7 is amplified by five times. Then, the second transmission rod 9 further amplifies the rotation speed by meshing with the third transmission gear 11 and the fourth transmission gear 13, and the rotation speed is increased by five times again. Finally, the entire system effectively amplifies the rotation speed of the first transmission rod 7 by twenty-five times. This speed-up effect ensures that the drive device can quickly convert the originally low input rotation speed into a high enough output rotation speed, so that the wire gyro can reach the required high speed rotation. High rotation speed is the key to normal launching of the wire gyro. Only when the gyro rotation speed is fast enough, can the wire gyro be effectively launched from the clamp by using centrifugal force, ensuring that the gyro rotates stably and maintains its gyro effect. Through such a transmission ratio design, not only the required high speed rotation can be achieved, but also the efficiency of the drive device is guaranteed. Each time the rotating handle is rotated, the operator exerts less effort, but the rotation speed is effectively amplified, so that the entire device is more easy to operate. At the same time, since the speed-up process is achieved through gear transmission, this makes the device able to run at high speed without excessive energy consumption due to excessive friction, improves the mechanical efficiency, and prolongs the service life of the device.

Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
