[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1-4 As shown, a UAV tripod shown in the figure includes a UAV 1 and a clamping mechanism arranged at the bottom of the UAV 1, and the clamping mechanism includes a working component and a clamping component;

[0026] The working assembly includes a pull ring 2. The pull ring 2 is provided at the bottom of the drone 1. The top of the pull ring 2 is fixedly connected to a fixed plate 3. The inner wall of the fixed plate 3 is slidably connected to a connecting column 4. The top of the fixed plate 3 is fixedly connected to a first spring 5. The top of the connecting column 4 is fixedly connected to a sliding plate 6.

[0027] The clamping assembly includes a shell 7, the outer wall of the sliding plate 6 is slidably connected to the shell 7, the top of the sliding plate 6 is fixedly connected to the limit plate 8, the inner wall of the limit plate 8 is rotatably connected to the first connecting plate 9, the top of the first connecting plate 9 is rotatably connected to the connecting block 10, and one side of the connecting block 10 is fixedly connected to a fixing ring 11.

[0028] Among them, such as Figure 3 As shown, the fixed plate 3 is provided with a sliding groove that matches the connecting column 4. The connecting column 4 forms a sliding structure with the fixed plate 3 through the pull ring 2, which is conducive to the pull ring 2 pulling the connecting column 4 to move in the groove of the fixed plate 3, providing force for the sliding plate 6 to move, and driving the fixed ring 11 to move.

[0029] Among them, such as Figure 3 As shown, the housing 7 is provided with a sliding groove that matches the sliding plate 6. The sliding plate 6 forms a sliding structure with the housing 7 through the connecting column 4, which is beneficial to prevent the sliding plate 6 from falling when sliding and lifting.

[0030] Among them, such as Figure 2 As shown, two groups of limit plates 8, first connecting plates 9, connecting blocks 10 and fixing rings 11 are provided. The positional relationship of the two groups of limit plates 8, first connecting plates 9, connecting blocks 10 and fixing rings 11 is symmetrically distributed about the midpoint of the fixing plate 3, which is conducive to bidirectional clamping and fixing of the fixing ring 11 to prevent it from falling off.

[0031] Example 2

[0032] like Figure 1 、 Figure 2 and Figure 4As shown, this embodiment further illustrates Example 1, a fixing rod 12 is provided at the bottom of the drone 1, the outer wall of the fixing rod 12 is fixedly connected to a fixing block 13, the bottom end of the fixing block 13 is fixedly connected to a sliding column 14, the outer wall of the sliding column 14 is slidably connected to a hollow column 15, the bottom end of the sliding column 14 is fixedly connected to a second spring 16, the bottom of the hollow column 15 is fixedly connected to a conical block 17, the inner wall of the conical block 17 is fixedly connected to a third spring 18, the bottom end of the third spring 18 is fixedly connected to a limiting cone 19, one end of the fixing rod 12 is fixedly connected to a second connecting plate 20, and the bottom of the drone 1 is fixedly connected to a support frame 21.

[0033] Among them, such as Figure 4 As shown, the conical block 17 is provided with a sliding groove that matches the limiting cone 19. The limiting cone 19 forms a buffer structure with the conical block 17 through the third spring 18, which is conducive to the limiting cone 19 being inserted into the ground. It relies on the elastic support of the third spring 18 and plays a buffering function. It can also provide reverse insertion force into the ground to prevent it from falling.

[0034] Among them, such as Figure 1 As shown, three groups of fixed rods 12, fixed blocks 13, sliding columns 14, hollow columns 15, second springs 16, tapered blocks 17, third springs 18 and limiting cones 19 are provided. The positional relationship of the three groups of fixed rods 12, fixed blocks 13, sliding columns 14, hollow columns 15, second springs 16, tapered blocks 17, third springs 18 and limiting cones 19 is symmetrically distributed about the center of the drone 1, which is beneficial to increasing the landing stability of the drone 1 and allows it to land on uneven ground.

[0035] When in use: First, the user pulls the pull ring 2, so that the pull ring 2 drives the connecting column 4 to move in the groove of the fixed plate 3, and at the same time drives the sliding plate 6 to slide in the sliding groove of the inner wall of the shell 7. The elastic force of the first spring 5 plays a supporting role. When the sliding plate 6 slides downward, it pulls the first connecting plate 9 to move, and the first connecting plate 9 pulls the fixing ring 11 to move, so that the fixing ring 11 rotates and disengages from the support frame 21, so that the structure can be quickly disassembled;

[0036] Finally, after the drone 1 descends, the limiting cone 19 first contacts the ground, so that the limiting cone 19 will be inserted into the ground and will also shrink into the groove of the conical block 17. The third spring 18 will play the role of elastic support, which can provide a certain power for the limiting cone 19 to insert into the ground. At the same time, the sliding column 14 will shrink into the groove of the hollow column 15, and the second spring 16 will play the role of buffer support, so that the drone 1 can land stably on the ground and prevent damage to the wings caused by falling.
