[0022] As Figures 1-5As shown in the utility model are connected to the connecting piece for toy aircraft, including propeller connecting head 1 and power device connecting head 2. Among them, propeller connecting head 1 includes base 101 and the connecting shaft 102 of integrally arranged in the center position of base 101, and the connecting shaft 102 is used to be fixedly connected with propeller 4;Power device connecting head 2 includes seat body 201 and the rotating shaft 202 of integrally arranged in the center position of seat body 201, and the rotating shaft 202 is used to be connected with the power device of toy aircraft, in this embodiment, the power device includes an electric motor 5, the power output shaft of the electric motor 5 is connected with gear transmission mechanism 6, and the power output end of gear transmission mechanism 6 is fixedly connected with rotating shaft 202. At this time, as shown in the utility model are connected to the connecting piece for toy aircraft, Figures 1 to 4 As shown, base 101 and seat body 201 are both set to disc-shaped structure and position is opposite, and the position of connecting shaft 102 and rotating shaft 202 is opposite.

[0023] Moreover, the propeller connector 1 and the power device connector 2 are connected together by magnetic attraction. That is, a magnetic attraction structure is arranged between the propeller connector 1 and the power device connector 2, and the magnetic attraction structure makes the two more convenient and fast to disassemble and assemble. Thus, when the toy aircraft falls from a high altitude and collides, the propeller connector 1 and the power device connector 2 will be separated, thereby effectively avoiding damage to the propeller structure. In the embodiment, the magnetic attraction structure is composed of two magnetic pieces 3. In order to ensure that the two magnetic pieces 3 are conveniently installed and fixed, specifically, an installation groove 301 is formed at the center of the base 101 of the propeller connector 1, and an installation groove 301 is also formed at the center of the seat body 201 of the power device connector 2, and the two installation grooves 301 are located on the two opposite surfaces of the base 101 and the seat body 201. Then, the two magnetic pieces 3 are separately installed and fixed in the two installation grooves 301, one magnetic piece 3 is fixed in the propeller connector 1, and the other magnetic piece 3 is fixed in the power device connector 2. At this time, the opposite ends of the two magnetic pieces 3 have opposite magnetic poles, thereby ensuring that the propeller connector 1 and the power device connector 2 can be smoothly connected together. In addition, in order to make the structure of the utility model various, the magnetic attraction connection can also be formed by other structures, for example, the magnetic attraction structure is composed of a magnetic piece and a metal piece. Similarly, an installation groove 301 is formed at the center of the base 101 of the propeller connector 1, and an installation groove 301 is also formed at the center of the seat body 201 of the power device connector 2, and the two installation grooves 301 are located on the two opposite surfaces of the base 101 and the seat body 201. Then, the magnetic piece and the metal piece are separately installed and fixed in the two installation grooves 301, that is, the magnetic piece is fixed in the propeller connector 1 or the power device connector 2, and the metal piece is correspondingly fixed in the other connector. The magnetic piece can be a magnet or other metal with magnetism, and has sufficient magnetic force, thereby ensuring that the propeller connector 1 and the power device connector 2 are reliably connected. Moreover, the magnetic piece and the metal piece can be circular, square, diamond-shaped or other shapes, and the shape of the installation groove 301 corresponds to the shape of the magnetic piece and the metal piece.

[0024] To further improve the reliability of this utility model, in this embodiment, four elastic arc-shaped buckles 22 are evenly spaced around the base 201 of the power device connector 2. Specifically, the arc-shaped buckles 22 are arranged around the axis of the rotation shaft 202 and are integrally formed with the base 201. Moreover, to ensure that the arc-shaped buckles 22 are elastic, each arc-shaped buckle 22 extends from the base 201 of the power device connector 2 towards the propeller connector 1 and bends inward. Specifically, the extension direction of the arc-shaped buckles 22 is along the axial direction of the rotation shaft 202, thereby ensuring that each arc-shaped buckle 22 is arranged around the same center, which is beneficial to improving the stability of the connection. Furthermore, the arc-shaped buckles 22 are slightly curved inward in the extension direction, thereby forming a certain degree of elasticity through the arc structure. Meanwhile, the base 101 of the propeller connector 1 is provided with arc-shaped protrusions 12 at equal intervals, the same number as the number of arc-shaped buckles 22. Specifically, the arc-shaped protrusions 12 are integrally set on the base 101 and are arranged around the axis of the connecting shaft 102. The surface of the arc-shaped protrusion 12 that contacts the arc-shaped buckle 22 is an arc surface, and its circumference near the bottom of the arc-shaped buckle 22 is longer, while its circumference near the top of the arc-shaped buckle 22 is smaller. During installation, the propeller connector 1 and the power unit connector 2 can be connected together by the corresponding snap-fit ​​of the arc-shaped protrusions 12 and the arc-shaped buckles 22. Since the connection is made by snap-fit, the propeller connector 1 and the power unit connector 2 are easy to assemble and disassemble. The combination of magnetic attraction and snap-fit ​​connection ensures the reliability of the toy aircraft during use and ensures that the propeller connector 1 and the power unit connector 2 can be effectively separated when the toy aircraft falls from a high altitude to the ground, thereby effectively avoiding damage to the propeller structure. Furthermore, the top of each arc-shaped buckle 22 can be designed with an inwardly inclined chamfered structure 221, making installation smoother and facilitating the insertion of the arc-shaped boss 12. Additionally, the inner side of each arc-shaped buckle 22 is provided with a cavity structure 223, ensuring both the elasticity of the arc-shaped buckle 22 and the reliability of the connection between the arc-shaped boss 12 and the arc-shaped buckle 22. Moreover, the number of arc-shaped buckles 22 and arc-shaped bosses 12 can be set to other quantities according to actual needs, such as three, five, etc.

[0025] Since the propeller connector 1 and the power unit connector 2 need to rotate synchronously to ensure the stability and reliability of the toy aircraft during use, four limiting slots 21 are evenly spaced around the base 202 of the power unit connector 2. As shown in the figure, in this embodiment, the limiting slots 21 are formed by the gap between two adjacent arc-shaped buckles 22, thereby simplifying the structural design of this utility model and making the structural design of this utility model easier and more reasonable. Of course, other methods can also be used to form the structure. At the same time, the base 101 of the propeller connector 1 is evenly spaced around the base 101 with the same number of limiting protrusions 11 as the limiting slots 21; specifically, each limiting protrusion 11 is integrally set on the base 101 and is arranged around the axis of the connecting shaft 102, and there is one limiting protrusion 11 between each two adjacent arc-shaped protrusions 12; and as shown in the figure. Figures 1 to 3 As shown, the two sides of each limiting protrusion 11 are inclined from top to bottom and from outward to inward, respectively. Similarly, the two sides of each arc-shaped buckle 22 are also designed as inclined surfaces 222 from bottom to top and from outward to inward. By designing the arc-shaped buckle 22 with a larger bottom and a smaller top, both elasticity and ease of insertion of the limiting protrusion 11 are ensured. During installation, the corresponding engagement of the limiting protrusion 11 and the limiting slot 21 restricts the relative rotation of the propeller connector 1 and the power unit connector 2, thereby achieving synchronous rotation. Furthermore, the number of limiting slots 21 and limiting protrusions 11 can be set to other quantities according to actual needs, such as three, five, etc.

[0026] When installing the propeller connector 1 and the power unit connector 2, the arc-shaped protrusion 12 is aligned with the arc-shaped buckle 22, and then pressed firmly to snap the arc-shaped protrusion 12 into the arc-shaped buckle 22. Simultaneously, the limiting protrusion 11 also snaps into the limiting groove 21. At this point, the two magnetic components 3 are attracted together, thus completing the installation of the propeller connector 1 and the power unit connector 2. This connection method effectively achieves a detachable connection between the propeller connector 1 and the power unit connector 2, and is convenient and quick to install and remove, while ensuring the reliability of the connection. Furthermore, the propeller connector 1 and the power unit connector 2 can also be configured in other structural forms. For example, the propeller connector 1 can be formed by directly connecting and fixing several limiting protrusions 11 to the connecting shaft 102, with an arc-shaped protrusion 12 integrally provided between each pair of adjacent limiting protrusions 11. In other words, the structural design of the propeller connector 1 and the power unit connector 2 only needs to meet the above-mentioned structural arrangement and connection method of the components.
