[0041] It can be understood that, first, the ejection component 7 is arranged to cooperate with the ignition component 9. The ejection component 7 has a strong ejection force and can avoid jamming. The ignition component 9 can stably ignite the ejection component 7, thereby ensuring the reliable launch of the drone. Secondly, the ignition component 9 can conveniently and stably establish a connection between the mounting tube 1 and the packaging tube 2, which is convenient for the rapid replacement of the packaging tube 2. Finally, the rotating component 10 can be used for switching the mounting tube 1 when it is in use and stored, avoiding bumps caused when the mounting tube 1 is opened when not in use.
[0042] A specific application of this embodiment is: Figure 5 This is the reset state of the device. When it is needed, the installation tube 1 is opened to 70° on the packaging tube 2 by the rotating component 10 and locked. The packaging tube 2 is installed on the installation tube 1 by the positioning component 8. Whether to install the waterproof seal 3 is selected according to the actual use. Figure 1 The figure shows a state ready for launch, at which the ignition component 9 and the ejection component 7 are also docked, and the ejection component 7 is ignited by the ignition component 9, and the ejection component 7 outputs power to eject the UAV located inside the packaging tube 2 into the air;
[0043] The connection of the positioning component 8 is as follows: the bottom of the packaging tube 2 is inserted into the interior of the installation tube 1, the rotating pin 82 is connected with the upper opening of the rotating groove 85, and the packaging tube 2 is rotated. At this time, the rotating pin 82 rotates downward along the rotating groove 85. When the bottom of the tube bottom cover 21 fits with the top of the positioning seat 84, the positioning pin 86 at this time is plugged into the positioning hole 83 under the action of the spring, and the packaging tube 2 and the installation tube 1 are installed. The front end of the conductive pin 93 is connected with the interior of the combustion chamber 71; when it is necessary to disengage, the packaging tube 2 is rotated in the opposite direction with force. At this time, the positioning pin 86 is disengaged from the positioning hole 83 under the action of the spring and the rotation force, and then the rotating pin 82 is rotated out of the rotating groove 85 to disengage;
[0044] The ejection component 7 and the ignition component 9 cooperate to inject fuel into the combustion chamber 71. At this time, the conductive pin 93 is energized to burn the fuel. The pressure generated by the explosion of the fuel enters the lower end of the piston 72 through the small hole on the side of the combustion chamber 71 and pushes the connecting pin 73 upward. At this time, the shear screw 74 is cut off under the action of the explosion force, and the piston 72 together with the drone at the upper end is ejected from the packaging tube 2.
[0045] The use of the rotating component 10 is as follows: Figure 5 In the state shown, the locking pin 1004 is in an inserted state with the locking hole 1009 at the upper end under the squeezing effect of the diamond block 1005 on the arc block 1002. Hold the handle 1006 and rotate it. The long side of the diamond block 1005 is out of contact with the arc block 1002. Under the action of the reset spring 1003, the locking pin 1004 is driven to disengage from the locking hole 1009 at the upper end. The mounting tube 1 and the flip plate 6 are rotated along the rotating axis between the flip plate 6 and the base plate 5. After the mounting tube 1 and the base plate 5 form 70°, the handle 1006 is rotated in the opposite direction. At this time, the long side of the diamond block 1005 squeezes the arc block 1002 and prompts the locking pin 1004 to be inserted into the locking hole 1009 at the lower end. The locking rod 1007 follows the rotation and is also inserted into the lock sleeve 1010. At this time, the mounting tube 1 is opened to 70° and locked.
