Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0023] This detailed implementation manner is a drone grabbing device, and its structural schematic diagram is as shown in Figure 1 and includes a bottom support mechanism 1, a mounting bracket 3, a clamping plate 2 and an adjusting shaft 6. A guiding slide bar 5 is horizontally and slidably mounted on the inner wall of the mounting bracket 3. The guiding slide bars 5 are symmetrically distributed in pairs. One end of the guiding slide bar 5 away from the mounting bracket 3 is fixed to the clamping plate 2, and the guiding slide bars 5 are symmetrically distributed on both sides of the clamping plate 2

[0024] Referring to Figure 2 、 Figure 3 , an inner chute 8 is horizontally opened on the inner wall of the mounting bracket 3, and the guiding slide bar 5 slides into the inner chute 8. An adjusting shaft 6 is rotatably mounted on the side wall of the mounting bracket 3. One end of the adjusting shaft 6 is fixedly connected with a driving bevel gear. The adjusting shaft 6 corresponds to the inner chute 8, and a driven bevel gear 7 is rotatably mounted at the center position of the inner chute 8. The driven bevel gear 7 and the driving bevel gear are vertically distributed and meshed with each other. A driving screw 9 is fixedly mounted at the center of the driven bevel gear 7. The external threads of the driving screw 9 are arranged in opposite directions centered on the driven bevel gear 7. The driving screw 9 is in threaded connection with the guiding slide bar 5, and the guiding slide bar 5 slides relatively along the inner chute 8

[0025] Referring to Figure 4, The bottom support mechanism 1 is arranged on the outer wall of the clamping plate 2. The bottom support mechanism 1 includes a vertical rod 11, a lifting rod 13, and a bottom rod 14. The vertical rod 11 is rotatably connected to the surface of the clamping plate 2. The lifting rod 13 is arranged at one end of the vertical rod 11 away from the clamping plate 2. The lifting rod 13 penetrates into the end of the vertical rod 11 towards its interior. The bottom rod 14 is rotatably installed at one end of the lifting rod 13 away from the vertical rod 11. There is a notch 15 on the outer wall of the vertical rod 11, and a rotating block 10 is rotatably installed inside the notch 15. The interior of the vertical rod 11 is a hollow structure, and an internal screw rod 12 is rotatably embedded therein. The internal screw rod 12 is fixedly connected to the rotating block 10. The bottom rod 14 is rotatably connected to the lifting rod 13, and the two are vertically distributed.

[0026] Working principle: When in use, first connect the mounting frame 3 to the bottom of the drone. Then place the item along the bottom of the mounting frame 3 and rotate the adjusting shaft 6. The adjusting shaft 6 drives the active bevel gear to rotate, and the driven bevel gear 7 rotates under force, causing the driving screw rod 9 to rotate. The two guiding slide bars 5 are threadedly connected to the driving screw rod 9. Driven by the thread force, they slide along the inner chute 8. The adjusting shafts 6 on both sides of the mounting frame 3 rotate simultaneously, and thus the guiding slide bars 5 move relatively closer, driving the clamping plate 2 to gradually approach and clamp the side wall of the item. Then lift the entire mounting frame 3, and the bottom of the item leaves the ground. At this time, the bottom support mechanism 1 can be unfolded. Rotate the vertical rod 11 so that it rotates horizontally with the clamping plate 2 to the vertical direction, and rotate the bottom rod 14 to correspond to the bottom of the item. Operate the rotating block 10 to rotate, and the internal screw rod 12 fixedly connected to the rotating block 10 rotates. Then the lifting rod 13 slides into the interior of the vertical rod 11, and the bottom rod 14 also rises and gradually approaches and fits against the bottom end surface of the item. At this time, the item is completely clamped within the mounting frame 3. The bottom support structure is in a retracted state when not in use to avoid damage caused by contact with the ground. The rotational connection freedom between the vertical rod 11 and the clamping plate 2 is not high. Therefore, the vertical rod 11 can be automatically locked after rotation and cannot move by its own gravity. It needs to be flipped by an external force.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
