[0025] It comprises a body 1 and wings 2, wherein the wings 2 are two and are symmetrically arranged on the left and right sides of the body. It also comprises:

[0026] A mounting seat 3, wherein the mounting seat 3 is fixedly arranged at the root of the wing 2, and the mounting seat 3 is covered on the side wall of the fuselage 1;

[0027] A connecting sleeve 4 is fixed on the side panel of the body 1;

[0028] The connecting plate 5 is fixed on the mounting seat 3 and is movably inserted into the connecting sleeve 4;

[0029] A positioning sleeve 6, wherein the positioning sleeve 6 is fixedly arranged on the inner lower surface of the body 1;

[0030] A positioning rod 7 is movably inserted into the connecting plate 5 and is movably inserted into the positioning sleeve 6;

[0031] The threaded sleeve 8 is fixedly arranged on the inner wall of the body 1, and a threaded groove is integrally formed on the outer wall of the positioning rod 7. The positioning rod 7 is screwed through the threaded sleeve 8 through the threaded groove;

[0032] A transmission shaft 9 is screwed onto the top plate of the machine body 1 through a bearing;

[0033] An inner hexagonal sleeve 10, wherein the inner hexagonal sleeve 10 is fixedly arranged on the lower end of the transmission shaft 9;

[0034] The hexagonal rod 11 is fixedly provided at the upper end of the positioning rod 7, and the hexagonal rod 11 is movably inserted into the lower end of the hexagonal sleeve 10;

[0035] A torsion spring 12, wherein the torsion spring 12 is fixedly mounted on the hexagonal sleeve 10, and the movable end of the torsion spring 12 is fixedly mounted on the inner wall cover of the body 1;

[0036] A one-way ratchet 13, wherein the one-way ratchet 13 is sleeved and fixed on the hexagonal socket 10;

[0037] The elastic frame 14 is fixedly mounted on the inner wall of the body 1 and is movably mounted on the connecting plate 5;

[0038] The pawl 15 is fixedly mounted on the movable end of the elastic frame 14 and is engaged with the one-way ratchet 13;

[0039] A support shaft 16, wherein the support shaft 16 is rotatably mounted in the body 1 via a bearing;

[0040] A driving gear 17 is sleeved and fixed on the support shaft 16;

[0041] The driven gear 18 is sleeved and fixed on the hexagonal socket 10, and the driving gear 17 and the driven gear 18 are meshed with each other;

[0042] A ratchet hub 19, wherein the ratchet hub 19 is fixedly disposed on the lower end of the support shaft 16;

[0043] A transmission gear 20, wherein the transmission gear 20 is fixedly disposed on the movable shaft of the ratchet hub 19;

[0044] The rack 21 is fixedly arranged on the side of the connecting plate 5, and the transmission gear 20 and the rack 21 are meshed with each other.

[0045] When using this device, when the wing 2 is not installed, the positioning rod 7 is lifted to the top of the connecting sleeve 4. When installing the wing 2, the connecting plate 5 is inserted into the connecting sleeve 4 and the mounting seat 3 is pushed against the outer wall of the body 1. The connecting rod is inserted into the interior of the body 1 and pushes the elastic frame 14, so that the pawl 15 on the elastic frame 14 disengages the one-way ratchet 13, and then the hexagonal sleeve 10 is loosened, and the torsion spring 12 drives the hexagonal sleeve 10 to rotate, and then the positioning rod 7 is driven to rotate through the hexagonal rod 11. The positioning rod 7 cooperates with the threaded sleeve 8 through the threaded groove, so that the positioning rod 7 rotates and descends, so that the positioning rod 7 passes through the connecting plate 5 and is inserted into the positioning sleeve 6, so that the connecting plate 5 is locked and fixed by the positioning rod 7, that is, the installation of the wing 2 is completed. When disassembling the wing 2, the transmission shaft 9 is first used to drive the hexagonal sleeve 10 to rotate, thereby lifting the positioning rod 7 and disengaging the connecting plate 5. During this process, the hexagonal sleeve 10 rotates to tighten the torsion spring 12. Then, the wing 2 is pulled to pull the connecting plate 5 out of the fuselage 1. When the connecting plate 5 is separated from the elastic frame 14, the pawl 15 is pressed against the one-way ratchet 13 to perform a one-way limit lock on the hexagonal sleeve 10. When the connecting plate 5 is pulled outward, the transmission gear 20 is driven to rotate through the rack 21. The transmission gear 20 drives the support shaft 16 to rotate through the ratchet hub 19, thereby driving the driving gear 17 to rotate. The driving gear 17 drives the hexagonal sleeve 10 to continue to rotate in the direction of tightening the torsion spring 12 through the driven gear 18, thereby completing the disassembly of the wing 2.

[0046] Compared with the prior art, the beneficial effects of the present invention are:

[0047] 1. This device is provided with a mounting seat 3 on the wing 2, a connecting sleeve 4 on the upper cover of the body 1, and a connecting plate 5 on the mounting seat 3.

[0048] 2. This device is provided with a hexagonal sleeve 10 of the transmission cylinder in the body, and a hexagonal rod 11 is provided on the positioning rod 7, and then a torsion spring 12 and a corresponding one-way locking structure are provided on the hexagonal sleeve 10, so that when the connecting plate 5 is pulled out, the hexagonal sleeve 10 can be driven to rotate and the torsion spring 12 can be further tightened, so that when the wing 2 is installed again, the torsion spring 12 can drive the hexagonal sleeve 10 to automatically rotate and place the positioning rod 7 on the connecting plate 5.
