The four corners of one side of the locking sleeve 62 are fixedly connected to a sliding rod 63. One side of the sliding rod 63 passes through one side of the movable block 4. A spring 64 is provided on the surface of the sliding rod 63. One side of the spring 64 is fixedly connected to the surface of the locking sleeve 62, and the other side of the spring 64 is fixedly connected to the surface of the movable block 4.

[0024] As a technical optimization solution of the present invention, by setting a folding mechanism 6, the wing 2 5 can be folded, avoiding the situation where the wing 2 5 and the wing 1 can only be in the unfolded state, resulting in the volume of the drone body 2 cannot be reduced, thereby improving the storage convenience of the drone body 2.

[0025] refer to Figure 5 One side of the slide rod 63 is fixedly connected with a reinforcement plate 7 , and the reinforcement plate 7 is located on the side of the movable block 4 away from the movable sleeve 3 .

[0026] As a technical optimization solution of the present invention, by providing a reinforcement plate 7, one end of the slide rod 63 can be stably limited to avoid the slide rod 63 from tilting and deforming during the movement, thereby improving the stability of the slide rod 63 in use.

[0027] refer to Figure 3 The top and bottom of the locking sleeve 62 are fixedly connected with a push block 8, and the push block 8 is located at the top and bottom of the wing 2 5.

[0028] As a technical optimization solution of the present invention, by providing the push block 8, the contact area between the user and the locking sleeve 62 can be increased, thereby avoiding a small contact area between the locking sleeve 62 and the user and improving the pushing efficiency of the locking sleeve 62.

[0029] refer to Figure 4 The side of the surface of the movable block 4 close to the movable sleeve 3 is fixedly connected to the limiting block 9, and the surface of the limiting block 9 contacts the surface of the locking sleeve 62.

[0030] As a technical optimization solution of the present invention, by setting the limit block 9, the locking sleeve 62 can be limited to prevent the locking sleeve 62 from moving excessively, resulting in the locking sleeve 62 being separated from the movable block 4, thereby improving the working stability of the locking sleeve 62.

[0031] refer to Figure 3 The surface of the movable block 4 is fixedly connected with a slide rail 10, and the surface of the slide rail 10 contacts the inner wall of the locking sleeve.

[0032] As a technical optimization solution of the present invention, by setting the slide rail 10, the sliding of the movable block 4 can be stabilized, avoiding shaking of the movable block 4 during sliding movement, causing the movable block 4 to loosen, and improving the sliding stability of the movable block 4.

[0035] The working principle and usage process of the present invention: When in use, the figure shows the wing 2 5 in an unfolded and fixed state. When the wing 2 5 needs to be folded, the locking sleeve 62 is pulled to the side away from the wing 1, and the locking sleeve 62 drives the slide bar 63 to move. The locking sleeve 62 compresses the spring 64. When the locking sleeve 62 moves to a certain distance, the locking sleeve 62 is separated from the locking plate 61, and the fixing effect between the movable sleeve 3 and the movable block 4 is lost. The wing 2 5 is rotated, and the wing 2 5 drives the movable block 4 to rotate inside the movable sleeve 3. When the wing 2 5 is rotated to a suitable angle, the folding and storage is completed. The wing 1 and the wing 2 5 are unfolded and fixed by a rigid snap-fit ​​assembly. The wing 2 5 will not loosen or displace during the operation of the drone body 2.

[0036] To sum up: the drone wing folding device, through the coordinated use of wing 1, drone body 2, movable cover 3, movable block 4, wing 2 5 and folding mechanism 6, solves the problem of folding and fixing the wings by driving gears with four motors, and fixing the unfolded wings by locking the gears with motors. During the flight of the drone, the wings will generate huge force. After being subjected to strong force, the gears will drive the output end of the motor to loosen, causing the wings to loosen, making it impossible for the drone to fly stably and safely, reducing the stability of the drone wings.
