[0033] Exemplarily, the base 1 may be configured to include a shell 11 having a through slot, one end surface of the shell 11 being connected to an upper sealing plate 12, and the other end surface being connected to a lower sealing plate 13, and the shell 11, the upper sealing plate 12, and the lower sealing plate 13 may be enclosed to form a receiving space.

[0038] In another example, the driving member 21 may be a steering gear, which is a position (angle) servo driver suitable for control systems that require angles to be constantly changed and maintained. The size and model of the steering gear need to be selected according to actual needs, and the torque of the steering gear is mainly considered during selection. The steering gear has a simple structure, light weight, and high control accuracy, which meets the lightweight requirements.
[0039] Among them, embedded nuts can be provided inside the housing 11 and on the steering gear mounting seat, and the steering gear is installed in the housing 11 through the embedded nuts and screws.

[0041] For example, the rocker arm can be driven by the steering gear to rotate within the range of 45° to 47°, so that the rocker arm is moved out of the slot, thereby releasing the constraint on the projectile carrier 4. In the embodiment of the present application, there is no specific limitation on the range of rotation of the rocker arm, and the projectile carrier 4 can be constrained or released by the rocker arm. The specific rotation range is set according to the actual situation.

The spring 34 is connected to a push rod 35, and the push rod 35 corresponds to the parachuted object carrier 4; when the restraining member 22 restrains the parachuted object carrier 4, the baffle 32 abuts against the push rod 35, the spring 34 is in a compressed state, and the push rod 35 is not in contact with the parachuted object carrier 4.
[0044] Exemplarily, the auxiliary component 3 can be configured to have a structure including a trigger member 31 , and the trigger member 31 can include a slide rod 311 .

[0045] Among them, the trigger member 31 can also include a push block 313, which is fixedly connected to the slide rod 311. The position of the push block 313 corresponds to the part of the rocker arm located in the slot. When the rocker arm is completely moved out of the slot, the rocker arm abuts against the push block 313 and pushes the push block 313 to slide in the slide groove 312.
[0046] In another example, the push block 313 is connected with a baffle 32, which is arranged above the projectile carrier 4, and the baffle 32 can move with the movement of the slide bar 311. A support plate 33 can also be installed inside the housing 11, and the support plate 33 is arranged above the baffle 32, that is, the baffle 32 is arranged at a position between the projectile carrier 4 and the support plate 33. A push rod 35 can be inserted on the baffle 32, and the axis of the push rod 35 extends in the vertical direction. The push rod 35 is sleeved with a spring 34, one end of the spring 34 is connected to the support plate 33, and the other end of the spring 34 is connected to the push rod 35.
[0047] It can be understood that a slope is provided on the side of the push block 313 close to the rocker arm to facilitate the rocker arm to push the push block 313 to move; a telescopic rod can be provided between the slide rod 311 and the lower sealing plate 13, and the telescopic rod is not marked in the figure. One end of the telescopic rod is connected to the lower sealing plate 13, and the other end is connected to the slide rod 311, or it can also be provided as other parts with elastic functions. Such a setting can reduce the probability of the slide rod 311 shaking randomly under normal conditions.
[0048] In the above embodiment, due to the provision of the trigger member 31, the baffle plate 32, the support plate 33, the spring 34 and the top rod 35, a force can be applied to the parabolic carrier 4 while releasing the constraints on the parabolic carrier 4, thereby reducing the probability of the parabolic carrier 4 being stuck and improving the accuracy of the projection.
[0049] In some embodiments of the present application, Figure 3 As shown, the parabolic object carrier 4 includes a restraining portion 41 and a connecting portion 42. One end of the restraining portion 41 is connected to the driving member 21, and the other end is connected to the connecting portion 42. The connecting portion 42 is provided with a connecting structure, and the parabolic object or the parabolic device is installed on the connecting portion 42 through the connecting structure.
[0050] Exemplarily, the projectile carrier 4 may be configured to have a structure including a restraining portion 41 and a connecting portion 42 , wherein one end of the restraining portion 41 is connected to the driving member 21 , and the other end is connected to the connecting portion 42 .
[0051] The constraint portion 41 can be integrally formed with the connection portion 42, or can be connected via a connector. Furthermore, the constraint portion 41 and / or the connection portion 42 can be manufactured using 3D printing technology. In the embodiment of the present application, the molding process and the connection method of the constraint portion 41 and the connection portion 42 are not specifically limited and are set according to actual conditions.
[0052] As another example, a connecting structure, such as an arc groove, a strip groove or the like, may be provided on the connecting portion 42. The structure may match the projectile. A suitable connecting portion 42 may be selected according to different types of projectiles or projectile equipment, thereby facilitating installation of different projectiles on the projectile carrier 4 and expanding the scope of application of the projectile device.
[0053] In the above embodiment, since the restraining portion 41 and the connecting portion 42 are provided, different projectiles can be thrown through the provided restraining portion 41 and the connecting portion 42, and the application range is wide.
[0054] The following is a description of the use of a throwing device provided by the present application. When in use:
[0055] S100: The parachutes are mounted on the parachutes carrier 4. After the UAV flies to the designated position, the driving member 21 is started. The output shaft of the driving member 21 drives the restraining member 22 to rotate. The restraining member 22 is removed from the parachutes carrier 4. The restraining member 22 releases the restraint on the parachutes carrier 4.
[0056] S200: When the constraint member 22 releases the constraint on the parabolic object carrier 4, the constraint member 22 can push the push block 313 to move, and the push block 313 drives the slide bar 311 to slide in the slide groove 312. The slide bar 311 drives the baffle 32 to move, and the baffle 32 is out of contact with the push rod 35, thereby releasing the compression on the spring 34. The push rod 35 moves toward the direction close to the parabolic object carrier 4 as the spring 34 returns to its original position. The push rod 35 applies a downward force to the parabolic object carrier 4 to push the parabolic object carrier 4 out of the shell 11.
