[0024] The limiting component includes a first limiting groove 6; a pair of the first limiting grooves 6 are opened at the bottom of the first fixed block 2; a pair of second limiting grooves 7 are opened at the top of the second fixed block 4; a limiting block 8 is fixedly connected to the pair of the second limiting grooves 7 by a spring; first through grooves 9 are opened on both sides of the first fixed block 2. When working, the first limiting groove 6 is fixed by the limiting block 8 fixedly connected to the second limiting groove 7 by a spring, so that when disassembling, the staff only needs to press the limiting block 8 through the first through groove 9, so that the staff can remove the second fixed block 4 together with the wing body 5 conveniently, which can facilitate the staff to carry out maintenance.

[0025] The locking assembly includes a power unit, a connecting unit and a second sliding groove 10; a group of the second sliding grooves 10 are opened at the bottom of the body 1; a group of sliding rods 11 are slidably connected in the second sliding grooves 10; the bottom of the sliding rods 11 are fixedly connected to the limiting rods 12; a third limiting groove 13 is opened on one side of the second fixing block 4; a power assembly is provided at the bottom of the body 1; the power unit and the connecting unit are used to drive a group of sliding rods 11 to move. When working, the first fixing block 2 is rotatably connected to the bottom of the body 1 through the third rotating shaft, so that when the drone needs to be stored, the wing body 5 of the drone can be prevented from being too unfolded, and the position of the wing body 5 can be adjusted to reduce the occupied space and avoid the existing need to disassemble the wing for storage. In addition, through the power unit and the connecting unit, the wing body 5 of the drone can be fixed in position when the drone is working.

[0026] The power unit includes a third fixed block 14; the third fixed block 14 is fixedly connected to the bottom of the body 1; electric telescopic rods 15 are fixedly connected to both sides of the third fixed block 14; a pair of telescopic ends of the electric telescopic rods 15 are fixedly connected to push blocks 16. When working, the pair of electric telescopic rods 15 drive the pair of push blocks 16 to move, so that a group of sliding rods 11 can be driven to move through the connecting unit, that is, a group of limiting rods 12 can be driven to insert into the third limiting groove 13, and the second fixed block 4 is limited, thereby preventing the wing body 5 from moving.

[0027] The connecting unit includes connecting rods 17; a group of the connecting rods 17 are rotatably connected to the sliding rods 11 through a first rotating shaft; the other ends of a pair of the connecting rods 17 are rotatably connected between the opposite side walls of the pushing block 16 through a second rotating shaft. When working, through the set group of connecting rods 17, a group of sliding rods 11 can be driven to slide at the same time under the drive of a pair of electric telescopic rods 15, so that a group of limiting rods 12 can be respectively inserted into a group of third limiting grooves 13, so as to limit the position of the wing body 5.

[0028] The top of the limiting block 8 is a slope 18 . During operation, the limiting block 8 having the slope 18 can make it easier for the staff to insert the limiting block 8 into the first limiting groove 6 when installing the second fixing block 4 .

[0029] Working principle: by setting the wing body 5 on the side wall of the second fixing block 4, the second fixing block 4 can be fixed by the limiting piece to achieve the effect of fixing the wing body 5. Therefore, the setting of the limiting piece can facilitate the staff to remove the wing body 5, thereby solving the problem that when the wings of the drone need to be repaired separately, because traditional drones generally fix the wings with bolts, it is not convenient to disassemble them. Most of the time, the bolts are removed by using tools, which is too inconvenient and affects the maintenance efficiency. The limiting block 8 is fixed by a spring in the second limiting groove 7, and the first limiting groove 6 is snap-fixed, so that when disassembling, the staff only needs to press the limiting block 8 through the first through groove 9, so that the staff can remove the second fixing block 4 together with the wing body 5, which is convenient for the staff to repair. By setting the first fixing block 2 to be rotatably connected to the bottom of the body 1 through the third rotating shaft, it can be avoided when the drone needs to be stored. If the wing body 5 of the drone is too large to be unfolded, the position of the wing body 5 can be adjusted to reduce the occupied space and avoid the existing need to disassemble the wing for storage. In addition, the power unit and the connecting unit are provided, so that the wing body 5 of the drone can be fixed in position when the drone is working. A pair of electric telescopic rods 15 are provided to drive a pair of pushing blocks 16 to move, so that a group of sliding rods 11 can be driven to move through the connecting unit, that is, a group of limiting rods 12 can be driven to insert into the third limiting groove 13, and the second fixed block 4 can be limited, thereby preventing the wing body 5 from moving. A group of connecting rods 17 are provided, and a group of sliding rods 11 can be driven to slide at the same time under the drive of the pair of electric telescopic rods 15, so that a group of limiting rods 12 can be respectively inserted into a group of third limiting grooves 13, thereby limiting the position of the wing body 5. The top of the limiting block 8 is an inclined surface 18, so that when the staff installs the second fixed block 4, the limiting block 8 can be more easily inserted into the first limiting groove 6.
