[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0024] like Figures 1 to 5 As shown, a UAV tripod retracting and extending device includes a base 3, four guide grooves 20 are opened inside the base 3, a slider 19 is slidably installed in each guide groove 20, and a pull rod 14 is installed on the side wall of each slider 19. A fourth connecting rod 13 is fixedly installed at one end of the connecting rod 14, and a third rotating shaft 12 is rotatably installed at the end of the fourth connecting rod 13. A third connecting rod 11 is fixedly installed on the third rotating shaft 12, and a second rotating shaft 10 is rotatably installed at the end of the third connecting rod 11. A second connecting rod 9 is fixedly installed on the second rotating shaft 10, and a first rotating shaft 8 is rotatably installed at the end of the second connecting rod 9. A first connecting rod 6 is fixedly installed on the first rotating shaft 8, and a sliding groove 7 is opened on the first connecting rod 6. The end of the pull rod 14 is slidably installed on the sliding groove 7;

[0025] A limiting groove 15 is defined inside the fourth connecting rod 13 , a limiting block 16 is slidably mounted inside the limiting groove 15 , and a support rod 17 is fixedly mounted on the bottom of the limiting block 16 . In this setting, the base 3 can provide simple protection for the drone. The guide groove 20 enables the pull rod 14 to pull the pull rod 14 when following the rotation of the tripod, so that the second link 9 and the third link 11 can be smoothly flipped upward, and the first magnet 21 and the second magnet 22 can be adsorbed together, which can fix the tripod even if it can be folded and retracted. The first rotating axis 8, the second rotating axis 10 and the third rotating axis 12 make the first link 6, the second link 9, the third link 11 and the fourth link 13 all rotatably connected. The end of the pull rod 14 is slidably installed on the sliding groove 7 so that the pull rod 14 slides on the first link 6 when driven by the slider 19. The limit groove 15 and the limit block 16 limit the support rod 17, and when the drone lands, the support rod 17 first touches the ground. The support rod 17 and the limit block 16 can slide on the fourth link 13, absorb part of the impact force, and play a buffering role in the landing of the drone, preventing the fuselage from directly contacting the ground and being damaged by impact.

[0026] like Figures 1 to 5 As shown, in a specific embodiment, a spring 18 is connected to the bottom of the fourth connecting rod 13, and the end of the spring 18 is fixedly connected to the support rod 17. In this setting, the spring 18 can play a shock-absorbing role in the landing of the drone.

[0027] like Figures 1 to 5 As shown, further, two dual-axis motors 23 are symmetrically mounted on the bottom of the base 3. Each dual-axis motor 23 has an output shaft 4 mounted at both ends. Each output shaft 4 is fixedly mounted with a connecting block 5, and each connecting block 5 is mounted on the first connecting rod 6. In this arrangement, the dual-axis motor 23 and the output shaft 4 provide power for the rotation of the connecting block 5, and the connecting block 5 is used to connect the output shaft 4 to the first connecting rod 6.

[0028] like Figures 1 to 5 As shown, four first magnets 21 are mounted on the bottom of the base 3, and a second magnet 22 is mounted on the second connecting rod. In this configuration, when the tripod is folded, the second connecting rod 9 and the third connecting rod 11 will flip upward, so that the first magnets 21 and the second magnets 22 are attracted together, which can compress the folding space and stabilize the tripod to prevent it from shaking due to the bumps of the drone.

[0029] like Figures 1 to 5 As shown, the second connecting rod 9 and the third connecting rod 11 are tilted when the tripod is opened. In this arrangement, the second connecting rod 9 and the third connecting rod 11 are tilted when the tripod is opened, ensuring that the second connecting rod 9 and the third connecting rod 11 can be smoothly flipped upward when the pull rod 14 pulls the fourth connecting rod 13, thereby allowing the first magnet 21 and the second magnet 22 to be attracted together.

[0030] like Figures 1 to 5 As shown, a body 1 is mounted on a base 3, and a plurality of propellers 2 are mounted on the body 1. In this configuration, various components of the drone are mounted inside the body 1, and the propellers 2 can facilitate the flight of the body 1.

[0031] The implementation principle of the drone tripod retraction and extension device of this embodiment is as follows: the drone tripod can provide a stable take-off and landing point for the drone, ensuring a smooth take-off and landing process, and can play a buffering role in the landing of the drone, preventing the fuselage from directly contacting the ground and being damaged by impact. When the support rod 17 contacts the ground, the support rod 17 and the limit block 16 can slide on the fourth connecting rod 13, and cooperate with the spring 18 to absorb part of the impact force, thereby protecting the drone's fuselage, motor, electronic equipment and other key components; when the drone needs to retract the tripod, the dual-axis motor 23 works, the output shaft 4 rotates, thereby driving the connecting block 5 to rotate, the connecting block 5 drives the first connecting rod 6 to rotate, and the pull rod 14 follows the first connecting rod The rod 6 rotates, and since the slider 19 on the pull rod 14 is slidably installed in the guide groove 20, the pull rod 14 will slide on the sliding groove 7. The other end of the pull rod 14 is fixedly installed on the fourth link 13, and the fourth link 13 will be pulled by the pull rod 14 in the direction of the first link 6. The first link 6, the second link 9, the third link 11 and the fourth link 13 are all rotatably connected. The second link 9 and the third link 11 are only squeezed upward due to their inclined shape and the limitations of each connection. Finally, the second magnet 22 on the second link 9 will be adsorbed together with the second magnet 22 at the bottom of the base 3, which fixes the various parts and prevents them from shaking due to the bumps of the drone.
