The top of the telescopic support rod 12... The lower support rod 11 is provided with a polygonal socket 17 that can be detachably engaged with a polygonal bracket slot 8. A universal ball sleeve 14 is connected to the bottom of the lower support rod 11. A universal ball 15 is rolled on the inner side of the universal ball sleeve 14. A base 19 is fixedly connected to the universal ball 15. At least three support claw arms 20 are pin-connected to the outer side of the base 19. A plug rod 21 is inserted and installed through the two side walls at the ends of the support claw arms 20. A second connecting plate 22 is provided at the upper end of the plug rod 21. A claw arm fixing mechanism is sleeved on the outer side of the lower support rod 11. Two sets of angle indicating devices are also provided on the outer side of the lower support rod 11.

[0030] This device, with its dual-purpose portable storage case and adjustable, ground-fixed support unit that can be stored inside the case, can be quickly assembled into a level take-off and landing platform for drones before outdoor drone shooting. This solves the problem of finding flat ground during outdoor drone aerial photography and avoids damage to the drone's gimbal and camera from uneven ground or improper operation.

[0031] To lock the telescopic plate 4, in this embodiment, a locking hole 5 is provided on one side of the telescopic plate 4, and a slidable locking seat 6 is provided through the side wall of the upper cover 2. The locking seat 6 is threadedly connected to an adjusting screw 7 that passes through its side plate, and the end of the adjusting screw 7 is rotatably engaged with the upper cover 2, so that rotating the adjusting screw 7 drives the locking seat 6 to move. When the adjusting screw 7 is screwed outward, the locking seat 6 exits the locking hole 5 to release the limitation on the telescopic plate 4; when the adjusting screw 7 is screwed inward, the locking seat 6 is inserted into the locking hole 5 to fix the telescopic plate 4.

[0032] The lower support rod 11 has a through first locking bolt 13 on its side wall, and the universal ball sleeve 14 has a through second locking bolt 16 on its side wall, which are used to fix the telescopic length of the telescopic support rod 12 and the rotation angle of the universal ball 15, respectively.

[0033] To achieve a quick and stable connection between the bracket device and the lower housing 1, in this embodiment, magnetic plates 18 are provided on the inner side of the polygonal bracket slot 8 and the top of the polygonal socket 17. The magnetic plates 18 are used to fix the polygonal bracket slot 8 and the polygonal socket 17 after insertion.

[0034] The claw arm fixing mechanism includes a fixing ring plate 24 fixedly disposed on the outside of the lower support rod 11. A spring 25 is provided on the top of the fixing ring plate 24. A sliding ring plate 26 is connected to the top of the spring 25. A limit seat 27 is fixedly installed on the top of the sliding ring plate 26. The number of limit seats 27 is the same as the number of supporting claw arms 20, and they are mutually locked and limited with the second connecting plate 22.

[0035] The sliding ring plate 26 and the second connecting plate 22 are locked together to limit the movement and fix the support claw arm 20. Sliding the sliding ring plate 26 downward releases the fixation of the limiting seat 27 on the second connecting plate 22, allowing the support claw arm 20 to rotate and unfold.

[0036] A lever 23 is provided on one side of the second connecting plate 22. The lever 23 is used to manually pull the second connecting plate 22 to pull the insertion rod 21 out of the soil.

[0037] Two sets of angle indicating devices are respectively set on two mutually perpendicular radial positions of the lower support rod 11. The angle indicating device includes a rotating shaft 28 fixed on the outside of the lower support rod 11. An angle scale plate 29 is rotatably mounted on the rotating shaft 28. An angle indicating plate 30 is fixedly provided at one end of the rotating shaft 28. An observation groove 31 is provided between the front and back sides of the angle indicating plate 30. An indicator line 32 is provided on the front side of the observation groove 31.

[0038] During the angle adjustment of the lower support rod 11, as the angle of the lower support rod 11 changes, the angle scale plate 29 automatically rotates under the action of gravity and remains vertical. The angle scale on the angle scale plate 29, which is aligned with the indicator line 32, can be quickly observed through the observation groove 31 and the indicator line 32 to determine the tilt angle of the lower support rod 11.

[0039] The working principle and usage process of this utility model are as follows: When not in use, the portable storage box can store the support device, drone, remote control, and other accessories through the support slot 9 and drone slot 10. When in use, the upper cover 2 is opened to take out the support device, drone, and accessories. Before taking off or landing the drone, the support device and portable storage box are first assembled to form a stable and horizontal take-off and landing platform. During the assembly process, the base 19 is first placed on the ground, and the sliding ring plate 26 is slid down to release the fixing of the limiting card 27 to the second connecting plate 22. Then, the support claw arm 20 is rotated and unfolded so that the end of the support claw arm 20 contacts the ground. The insertion rod is inserted by pressing the second connecting plate 22. Insert 21 into the ground soil to secure the support claw arm 20 to the ground. Then adjust the angles of the lower support rod 11 and the telescopic support rod 12 to make them vertical. During the adjustment, loosen the second locking bolt 16. The angles of the lower support rod 11 and the telescopic support rod 12 can be adjusted by rotating between the universal ball sleeve 14 and the universal ball 15. The tilt angle of the lower support rod 11 can be determined by the angle indicator device set on the outside of the lower support rod 11. During the adjustment of the angle of the lower support rod 11, as the angle of the lower support rod 11 changes, the angle scale plate 29 automatically rotates under the action of gravity to maintain verticality. The angle scale on the angle scale plate 29 aligned with the indicator line 32 can be quickly observed through the observation groove 31 and the indicator line 32 to determine the angle of the lower support rod 11. After adjusting the lower support rod 11 to a vertical position, loosen the first locking bolt 13 as needed to adjust the extension length of the telescopic support rod 12, thereby adjusting the support height of the bracket device for the handheld storage box. Note that after adjusting the angle of the lower support rod 11 and the extension length of the telescopic support rod 12, the first locking bolt 13 and the second locking bolt 16 need to be tightened again. After adjusting the bracket device, the handheld storage box can be inserted and connected to the polygonal bracket slot 8 at the bottom of the lower box 1 and the polygonal socket 17 at the top of the telescopic support rod 12, and magnetically fixed by the magnetic plate 18 to complete the assembly of the platform. Then, turn the adjusting screw 7 outward to pull out the locking seat 6 to release it. By inserting the locking socket 5, the telescopic plate 4 can be pulled outward, widening the top area of ​​the upper cover 2. This allows the upper cover 2 and the telescopic plate 4 to form a larger take-off and landing platform. The drone can then be placed on top of this platform for take-off and landing, providing a stable, level platform and improving the safety of take-off and landing operations. In summary, this device, through a dual-purpose portable storage case and an adjustable, ground-fixed support device that can be stored inside the case, can be quickly assembled into a level take-off and landing platform for drones before outdoor drone shooting, solving the problem of finding flat ground during outdoor drone aerial photography.To avoid damage caused by uneven ground or improper operation, which could result in the drone's gimbal and camera hitting protruding parts of the ground.
