[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In this device, a force-receiving member is provided. The force-receiving member is used to be installed at the bottom of the push rod through a fixed head. When the radio signal transmitter follows the drone to land and the drone moves rapidly downward, the force-receiving member can be impacted by the airflow. Since the top of the force-receiving member is a wedge-shaped structure and the side is an inclined plate-shaped structure, the airflow can be controlled to flow, so that the side of the force-receiving member can be stressed, which in turn drives the radio signal transmitter to be pushed, and then the radio signal transmitter is flipped, enabling the radio signal transmitter to rotate 180 degrees, making the radio signal transmitter face upward, enabling the radio signal transmitter to be positioned. At the same time, after the radio signal transmitter is flipped, the limit head can receive the spring force and move, and then be limited and fixed inside the side groove, so that the radio signal transmitter can be fixed, and the buffer member and the buffer plate can contact the ground, thereby buffering the impact force generated when contacting the ground, preventing the radio signal transmitter from directly contacting the ground and avoiding damage to the radio signal transmitter;

[0012] 2. In this device, a slow-down plate is provided. The slow-down plate is used to be embedded and installed inside the guide groove for fixation. When the drone is flying normally, the slow-down plate can be in a fixed state. When the radio signal transmitter is flipped, it can push the limit head, and then the push rod can be stressed and move. At the same time, the push rod contacts the wedge-shaped groove of the block through the wedge-shaped block, so that the block can be pushed to move upward, and the bottom of the block can be pulled out from the wedge-shaped groove of the slow-down plate, releasing the limit of the slow-down plate, and then being pushed by the spring outside the control rod of the installation member, so that the slow-down plate can move outward rapidly and automatically open. When the drone descends, it can be stressed through the bottom groove, thereby buffering the impact force generated during the fall. When the slow-down plate opens, the radio signal transmitter is in a flipped state, and thus it will not affect the protection of the radio signal transmitter. BRIEF DESCRIPTION OF THE DRAWINGS

A spring is sleeved outside the outer end of the push rod 501. A wedge block is provided at the outer end of the push rod 501.

At the inner top end of the mounting member 503, there is a pressing groove with a convex middle cylindrical structure at both ends, and the bottom of the pressing groove communicates with a rectangular groove.

Circular holes are provided inside the pushing plates 601, and round rods outside the side member 5 are inserted into the circular holes.

Wedge-shaped blocks are respectively provided on both sides of the bottom of the clamping plate 604. The wedge-shaped blocks contact the pushing plate 601. After the trigger rod 605 receives the power of the spring and moves downward, the wedge-shaped blocks of the clamping plate 604 can contact and fix the pushing plate 601; a trigger rod 605, the bottom of which is a rectangular structure, and the top of which is a cylindrical structure with a middle bulge at both ends. The top of the trigger rod 605 is installed inside the pressure groove of the mounting member 503 through a spring. After the device contacts the drone landing gear, the trigger rod 605 can pull down the device, so that the trigger rod 605 can rise, and then the bottom of the clamping plate 604 can release the fixation of the pushing plate 601, so that the pushing plate 601 can move, and then stably connect and fix with the drone landing gear.

[0033] As another implementation manner of the embodiment of the present invention, when the device is in use and it is not necessary to automatically trigger the slow-down plate 507 to open, when the slow-down plate 507 is continuously opened, the latch 506 can be pulled upward and removed, so that the slow-down plate 507 can continuously receive the power of the spring and move outward, so that the drone can be continuously kept in a slow-down state.

[0034] During use: When it is necessary to detect the lateral system, the drone is in a flying state. The direction scanning module 1 continuously scans the detection direction and simultaneously transmits the signal to the frequency processing module 2. When the direction deviates, the signal difference warning device 3 detects and emits a signal, and at the same time transmits the signal to the ground through the radio signal transmitter 4. When the radio signal transmitter 4 is initially installed, it can be installed in an inclined state above the landing gear of the drone. Then, pull down the radio signal transmitter 4 so that the bottom of the mounting member 503 can be close to the top of the landing gear of the drone, causing the trigger rod 605 to be pushed upward, the clamping plate 604 to rise, and the bottom of the clamping plate 604 to release the limit on the push plate 601, so that the moving plate 6 and the push plate 601 can be released from the limit, and the fixing plate 602 can drive the fixing block 603 to contact and fix with the landing gear of the drone, thereby enabling the stable installation of the device. When the drone needs to land, the drone is controlled to move quickly downward, causing the force-bearing member 403 to be stressed, thereby driving the radio signal transmitter 4 to flip so that the radio signal transmitter 4 can face upward, preventing the radio signal transmitter 4 from directly contacting the ground. Then, control the drone to land at a normal speed. When the radio signal transmitter 4 flips, it can push the push rod 501 to move, causing the wedge block of the push rod 501 to insert into the wedge groove of the clamping block 506, so that the clamping block 506 can be stressed and move upward, and the bottom of the clamping block 506 can be pulled out from the bottom of the buffer plate 507, enabling the buffer plate 507 to receive spring power and quickly move outward, so that the two buffer plates 507 can be deployed for use, enabling the bottom groove 508 to be stressed and slowing down the falling speed of the drone, making the drone safer when it lands. When the drone contacts the ground, the buffer plate 405 and the buffer member 406 can contact the ground, thereby buffering the impact force during the fall and preventing the radio signal transmitter 4 from being damaged.
