[0033] Example 2

[0034] like Figure 2-9As shown, in this embodiment, the signal box 2 is connected to the quick-connect device 6, and the quick-connect device 6 includes a mounting member 61, the mounting member 61 is fixedly connected to the signal box 2, and the mounting member 61 is hinged to the connecting member 62, wherein a hinged portion A611 is provided on the mounting member 61, and a hinged portion B621 is provided on the connecting member 62, the hinged portion A611 cooperates with the hinged portion B621, and a positioning hole A612 is provided on the mounting member 61, and a positioning hole B622 is correspondingly provided on the connecting member 62 to cooperate with the positioning hole A612, and the connecting member 62 is provided to be connected to the quick-connect connector B63, and the quick-connect connector B63 is connected to the drone.

[0035] The other parts of this embodiment are the same as those of Embodiment 1 and will not be described in detail.

[0036] The principle of this utility model is:

[0037] When the utility model is in use, the launching device is connected to the UAV during the process. When the first embodiment is adopted, the launching device can be directly connected to the UAV through the quick connector A3. When the second embodiment is adopted, the launching device can be adjusted in angle during the process, and then the quick connector B63 can be connected to the UAV. The quick connector A3 and the quick connector B63 are both existing mature technologies, and their use and principles will not be described in detail here.

[0038] When the utility model is in use, the bin body 4 and the cover body 1 can be opened by pulling the hand-held portion 5234 outward. During the process, when the hand-held portion 5234 is pulled outward, the spring 5233 contracts, and the card slot 5232 is separated from the hook 51, so that the cover body 1 can be opened. When closing, the same operation is adopted, the hand-held portion 5234 is pulled outward, and then the cover body 1 is closed. At this time, the hand-held portion 5234 is released, and under the action of the spring 5233, the hook 51 cooperates with the card slot 5232 to achieve the locking of the device. The box body 1 and the bin body 4 are opened by using the external hand-held portion 5234, thereby avoiding the cover body 1 from being opened due to external uncertain factors, thereby further ensuring the stability of use.

[0039] After the cover 1 is opened, the smoke bomb 7 can be installed in the magazine 41. In the process, the smoke bomb 7 is an existing one, and its principle is not repeated. The contact plate 72 on the cartridge case 71 is a metal part, which is connected to the static contact 73 inside to form a circuit. The contact plate 72 cooperates with the contact plate matching groove 411 in the magazine 41, so that the smoke bomb 7 can be placed in the magazine 7. The surrounding rubber ring placement groove 412 can make the placement of the smoke bomb 7 more stable. After the cover 1 is closed, the moving contact A111 cooperates with the static contact 74, and the moving contact B112 cooperates with the contact plate 73. Thus, a loop is formed, and the spring sheet 12 connected to the contact plate 11 can also effectively ensure the stability of the line connection. Therefore, when the drone receives the transmission signal, the line is connected, and the internal resistor of the smoke bomb 7 heats up, thereby igniting the warhead of the smoke bomb 7 to be fired outward, thereby forming smoke at the target location, which plays a role in blocking, covering and blocking the line of sight, and plays a role in combating crime and maintaining public order. The signal transmission and circuit control involved in the above process are existing mature technologies, which are not difficult to understand for those skilled in the art and will not be repeated here.
