[0035] In this embodiment, the connecting strap 6 is connected with the connecting ring 5 through an interlaced connection, the first Velcro 7 is adhesively connected with the second Velcro 8, and an equipment cavity 101 is opened on the left side and the right side of the interior of the fixing box 1, and a first movable hole 102 and a second plug hole 104 are opened on the left end and the right end of the fixing box 1, and a second movable hole 103 is opened on the left side and the right side of the front end of the fixing box 1, the two first movable holes 102 and the two second movable holes 103 are respectively communicated with the two equipment cavities 101, and the two release mechanisms 2 are respectively located inside the two equipment cavities 101.

[0036] Through the above solution: the movable connection between the connecting strap 6 and the connecting ring 5 allows the connecting strap 6 to be freely adjusted during use, so that the device can be used with drones of different models.

[0037] In this embodiment, the release mechanism 2 includes a motor 21 and a connecting pin 22, a driving pinion 23 is fixedly connected to the middle of the output end of the motor 21, a winding disk 24 is installed at the front of the output end of the motor 21, a connecting rope 25 is fixedly connected to one side of the outer surface of the winding disk 24, a hook 26 is fixedly connected to the end of the connecting rope 25, a driven pinion 27 is meshedly connected to one side of the outer surface of the driving pinion 23, a first linkage large gear 221 is fixedly connected to the end of the connecting pin 22 close to the motor 21, a limiting block 222 is fixedly connected to the upper side of the outer surface of the connecting pin 22 away from the motor 21, a second linkage large gear 28 is meshedly connected to one side of the outer surface of the first linkage large gear 221, the motor 21, the driving pinion The wheel 23, the driven pinion 27, the second linkage gear 28 and the first linkage gear 221 are all located inside the equipment cavity 101, and the motor 21 is fixedly connected to the lower wall of the equipment cavity 101, the driven pinion 27 is meshed with the second linkage gear 28, and the driven pinion 27 and the second linkage gear 28 are both movably connected to the inner wall of the equipment cavity 101, the output end of the motor 21 is movably connected with the second movable hole 103 through an interlacing connection, the winding disk 24 is located outside the fixed box 1, the connecting pin 22 is movably connected with the first movable hole 102 through an interlacing connection, the limit block 222 is located outside the fixed box 1, and the connecting pin 22 is engaged with the triangular connecting hole 12 in the fixing buckle 11 through the limit block 222.

[0038] Through the above scheme: the linkage structure of multiple gears in the release mechanism 2, when in use, the connecting rope 25 can be tightened by rotating the winding disk 24, so that the safety pin of the grenade can be pulled out by tightening the connecting rope 25. Subsequently, the winding disk 24 and the driving pinion 23 continue to rotate, and drive the first linkage large gear 221 on the connecting pin 22 to rotate through the linkage gear. The driving pinion 23 rotates three times before driving the first linkage large gear 221 to rotate one circle, which can avoid the safety pin in the grenade and the grenade being released at the same time. When the first linkage large gear 221 rotates, the limit block 222 located in the connecting pin 22 will be disengaged from the fixing buckle 11 used to fix the grenade, thereby realizing the release operation of the grenade.

[0039] It should be noted that the utility model is a drone grenade throwing device, the core of which lies in a dual release mechanism 2 system integrated in a fixed box 1. The system uses a motor 21 as a power core, and the output shaft of the motor 21 is directly connected to a driving pinion 23 and a winding disk 24, and the two rotate synchronously. In particular, a driven pinion 27 and two interconnected large gears are also carefully configured in the release mechanism 2, wherein the driven pinion 27 is responsible for transmitting power from the driving pinion 23 to the two interconnected large gears, and is designed with a unique reduction ratio, that is, the driving pinion 23 needs to rotate three circles before it can drive any of the interconnected large gears to complete a full circle of rotation.

[0040] After the grenade is securely fixed on the device, the hook 26 in the release mechanism 2 can be connected with the safety pin of the grenade to prepare for the subsequent automatic release. When starting the release process, it is only necessary to activate the motor 21, and the drive pinion 23 and the winding disk 24 will start to rotate. The rotation of the winding disk 24 first performs the task of automatically removing the safety pin of the grenade.

[0041] As the driving pinion 23 continues to rotate for three circles, the first linked large gear 221 (as one of the two linked large gears) completes one circle of rotation. During this rotation process, the position of a key component, the limit block 222, changes. This change directly causes the fixing buckle 11 that originally fastened the grenade to separate from the limit block 222, thereby achieving the safe release of the grenade from the device. The entire process does not require manual pre-operation of the safety pin, which greatly improves the safety of the operation.

[0042] In addition, the device is also equipped with an adjustable connecting strap 6. This design enables the device to be flexibly adapted to different types of drones, thereby enhancing its practicality and versatility. In summary, the utility model not only simplifies the complex process of drone grenade throwing, but also significantly improves the safety and convenience of operation.

[0043] At the same time, the device can be suitable for carrying and delivering a variety of ammunition types, such as smoke bombs and tear gas bombs that require the safety to be removed, which can be used in accordance with the carrying and delivery method of grenades. When carrying and delivering grenades and other ammunition types that do not require the safety to be removed, they can be directly fixed by the fixing strap 10. When it is necessary to remove the safety in the air to release smoke in the air or to spray tear gas in the air, it is only necessary to connect the first socket 13 in the fixing buckle 11 with the second socket 104 in the fixing box 1 through the limit pin 14 when fixing the ammunition type, so that the second half of the release process cannot be completed, and the operation of releasing smoke in the air can be achieved.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
