[0002] The unmanned aerial vehicle, abbreviated as "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self-contained program control device; generally, a UAV needs a navigation and positioning module to determine the space or geographical location where the UAV is located, so as to realize flight navigation and outdoor positioning. When installing the positioning module of the UAV, an installation structure of a navigation and positioning module for military UAVs is often used.

[0003] The prior art is a utility model with the publication number of CN209427046U. This patent discloses an installation structure of a navigation and positioning module for military UAVs. The patent uses a UAV body, and a receiving groove is opened at the top of the UAV body. A clamping groove is opened on one side of the inner wall of the receiving groove, and a positioning module installation mechanism is fixedly installed inside the receiving groove. A clamping member is installed at the top of the positioning module installation mechanism to match the clamping groove. Through the combined use of the installation column, the threaded groove, the anti-interference shielding plate and the stud, the navigation and positioning module can be firmly fixed inside the receiving groove; it solves the problem that the existing UAV does not have a rubber ring, making it difficult to protect the navigation and positioning module, and it is difficult to remove the clamping member from the inside of the clamping groove, so it is difficult for the staff to repair the positioning module installation mechanism inside the receiving groove.

[0004] In daily work, during the installation of the locator by the equipment, there is a problem that when installing the locator, bolts are generally used to fix the locator to the main body. The long-term use of the bolts is likely to cause loosening, resulting in the locator detaching from the main body and being difficult to use. Summary of the Utility Model

[0014] 1. In the present utility model, by providing a fixing device, when the device is in use, the user moves the positioning plate, and then the positioning plate slides on the surface of the sliding rod. When the positioning plate moves, it drives the first spring to displace and deform to generate elastic force. Then the positioning plate moves out of the inside of the second positioning groove, and then the locator loses its restraint and is pulled out of the inside of the first fixing block and the second fixing block. By providing the fixing device, the locator is effectively fixed, which plays a role in quickly fixing the locator, reducing the situation that when the device is in use, when the user fixes the locator, bolts are generally used to fix the locator to the main body, and the bolts are prone to looseness after long-term use, causing the locator to break away from the main body and being difficult to use, and improving the stability of the device.

[0023] Next, specifically describe the specific settings and functions of its fixing device 5 and protection device 6.

[0024] In this implementation: The fixing device 5 is arranged on the surface of the main body 1. The fixing device 5 includes a first fixing block 51 and a second fixing block 52. The first fixing block 51 is fixedly connected to the surface of the main body 1, the second fixing block 52 is fixedly connected to the surface of the main body 1, a positioner 54 is arranged inside the first fixing block 51 and the second fixing block 52, a first positioning groove 53 is opened on the side surface of the positioner 54, and a second positioning groove 55 is opened at one end of the positioner 54.

[0025] Specifically, the first fixing block 51 is clamped inside the first positioning groove 53, and a slide bar 57 is fixedly connected to the inner wall of the second fixing block 52.

[0026] In this embodiment: By setting the slide bar 57, the limiting movement of the positioning plate 56 can be realized, reducing the deviation that the positioning plate 56 is prone to occur during the movement of the equipment during use, resulting in difficulty in fixing the positioner 54 by the positioning plate 56.

[0027] Specifically, the surface of the slide bar 57 is slidably connected with a positioning plate 56, and the positioning plate 56 is clamped inside the second positioning groove 55. The setting of the positioning plate 56 facilitates the fixing of the positioner 54.

[0028] Specifically, a first spring 58 is sleeved on the surface of the slide bar 57, and both ends of the first spring 58 are fixedly connected to the surface of the positioning plate 56 and the inside of the second fixing block 52 respectively. The setting of the first spring 58 facilitates the application of a reset elastic force to the positioning plate 56.

[0029] In this embodiment: A protective device 6 is provided on the surface of the main body 1. The protective device 6 includes a protective cover 61 and a rotating block 62. The rotating block 62 is fixedly connected to the surface of the main body 1, and the protective cover 61 is rotatably connected to the surface of the rotating block 62. One end of the protective cover 61 is fixedly connected with a limiting block 63. A connecting block 64 is fixedly connected to the surface of the main body 1.

[0030] In this embodiment: By providing the protective cover 61, the locator 54 can be protected, reducing the situation that the locator 54 is easily affected by external forces and damaged during the use of the device.

[0031] Specifically, one end of the moving rod 65 is fixedly connected with a clamping rod 66, and the clamping rod 66 is clamped inside the limiting block 63. The setting of the clamping rod 66 facilitates the limitation of the protective cover 61.

[0032] Specifically, a second spring 68 is sleeved and connected to the surface of the limiting rod 67. The two ends of the second spring 68 are respectively fixedly connected to the surface of the moving rod 65 and the surface of the connecting block 64. The setting of the second spring 68 facilitates the application of a reset elastic force to the moving rod 65.

[0033] Working principle: When the device is in use, the user moves the positioning plate 56, and then the positioning plate 56 slides on the surface of the sliding rod 57. When the positioning plate 56 moves, it drives the first spring 58 to displace and deform to generate an elastic force. Then the positioning plate 56 moves out of the inside of the second positioning groove 55, and then the locator 54 is released from restraint. Pull the locator 54 out of the inside of the first fixing block 51 and the second fixing block 52. By providing the fixing device 5, the locator 54 can be effectively fixed, playing a role in quickly fixing the locator 54, reducing the situation that when the device is in use, when the user fixes the locator 54, bolts are generally used to fix the locator 54 to the main body 1, and the bolts are prone to looseness after long-term use, causing the locator 54 to separate from the main body 1 and being difficult to use, and improving the stability of the device.

[0034] When the device is in use, the user moves the moving rod 65. When the moving rod 65 moves, it drives the clamping rod 66 and the limiting rod 67 to move. Then when the limiting rod 67 moves, it drives the second spring 68 to displace and deform to generate an elastic force. Then the clamping rod 66 moves out of the inside of the limiting block 63, and then the protective cover 61 is released from restraint. By providing the protective device 6, the locator 54 can be effectively protected, playing a role in protecting the locator 54, reducing the situation that when the device is in use, the locator 54 is easily affected by external factors and damaged and difficult to use, and improving the practicality of the device.
