The unmanned aerial vehicle can lift and suspend some objects, and a hook release device is required for lifting and suspending the objects.

[0003] When the existing hook release device is in use, the hanging hook is controlled to open through a remote controller, then the lifting rope of the object to be lifted and suspended is placed between the hanging hooks, and then the hanging hook is controlled to close, so that the lifting rope is hung on the hanging hook. Then the unmanned aerial vehicle is started, so that the unmanned aerial vehicle lifts and suspends the object. Since the hook release device is fixedly connected to the bottom end of the unmanned aerial vehicle, when the hook release device is damaged, it cannot be disassembled separately for repair. Therefore, a hook release device that can be quickly disassembled is needed to facilitate the disassembly of the hook release device. Summary of the Utility Model

[0034] The fixing plate 21 is used for opening the clamping groove 23, the clamping block 22 is used for connecting the mounting frame 12 and the fixing plate 21, there are two clamping blocks 22 in each group, the clamping groove 23 is used for inserting the clamping block 22, the connecting groove 24 is used for inserting and clamping the clamping block 22, and the first magnetic plate 25 is used for limiting the clamped clamping block 22.

[0035] The clamping block 22 is clamped with the inside of the connecting groove 24, and the bottom end of the lateral surface of the clamping block 22 is adsorbed with the first magnetic plate 25;

[0036] Align the clamping block 22 with the clamping groove 23, push the clamping block 22 so that the clamping block 22 enters the clamping groove 23, and then push the clamping block 22 to one side so that the lateral surface of the clamping block 22 enters the connecting groove 24. At this time, the lateral surface of the clamping block 22 is clamped with the connecting groove 24, and at the same time, the first magnetic plate 25 is adsorbed with the bottom end of the lateral surface of the clamping block 22, thereby limiting the clamped clamping block 22, so that the mounting frame 12 is fixedly connected to the bottom end of the fixing plate 21 through the clamping block 22 and the first magnetic plate 25.

When the limiting plate 26 is not in use, the spring 28 is in an extended state. When the clamping block 22 enters the clamping groove 23, the top end of the clamping block 22 squeezes the limiting plate 26 through the inclined surface at the bottom end of the limiting plate 26, and the thrust pushes the spring 28 to contract through the limiting plate 26, so that the limiting plate 26 moves towards the groove 27 through the spring 28, so that the clamping block 22 enters the clamping groove 23. When the clamping block 22 moves into the connecting groove 24, the spring 28 expands, and the spring 28 drives the limiting plate 26 to squeeze the clamping block 22.

[0039] Working principle: When the component is in use, the mounting bracket 12 and the fixing plate 21 are in a separated state, the clamping block 22 and the clamping groove 23 are in a separated state, and the spring 28 is in an extended state; when the component is installed, the connecting frame 11 is fixedly connected to the bottom end of the drone, and then the mounting bracket 12 is held by hand, the clamping block 22 is aligned with the clamping groove 23, and the clamping block 22 is pushed. The top end of the clamping block 22 squeezes the limiting plate 26 through the inclined surface at the bottom end of the limiting plate 26, and the thrust pushes the spring 28 to contract through the limiting plate 26, so that the limiting plate 26 moves towards the groove 27 through the spring 28, so that the clamping block 22 enters the clamping groove 23, and then the clamping block 22 is pushed to one side, so that the lateral surface of the clamping block 22 enters the connecting groove 24.

[0040] In the above steps, through the interaction between the limiting plate 26 and the first magnetic plate 25, the clamped clamping block 22 can be limited.

[0041] Please refer to Figures 1 - 3 、 Figure 5 As shown, on the basis of the above-mentioned Embodiment 1, this embodiment further includes:

[0042] A limiting component;

[0044] The limiting block 31 is used for the clamping of the limiting frame 33. There are two limiting blocks 31 in each group, and the two side limiting blocks 31 are staggered. The second magnetic plate 32 adsorbs the clamped limiting frame 33, the second magnetic plate 32 limits the limiting frame 33, and the limiting frame 33 further limits the clamping block 22 clamped with the connecting groove 24.

[0046] The plugging hole 35, the limiting hole 34 and the limiting groove 36 are all used for the insertion of the limiting frame 33, so as to further limit the clamping block 22 clamped with the connecting groove 24.

[0047] Working principle: When the component is not in use, the limit frame 33 is engaged with the clamping block 22, and the limit frame 33 is adsorbed to the second magnetic plate 32; after the clamping block 22 is engaged with the connection groove 24, the limit hole 34, the insertion hole 35 and the limit groove 36 correspond to each other and are connected. At this time, hold the limit frame 33 by hand to separate the limit frame 33 from the limit block 31 and the second magnetic plate 32, then align the two ends of the limit frame 33 with the insertion hole 35, and push the limit frame 33 by hand to make the limit frame 33 sequentially inserted into the insertion hole 35, the limit hole 34 and the limit groove 36, so that the limit frame 33 further limits the clamping block 22 engaged with the connection groove 24;
