A propeller 3 is mounted at one end of each wing 2, and a blade protection mechanism 4 is provided at one end of each wing 2. The blade protection mechanism 4 includes an arc-shaped protective frame 43 located outside the propeller 3. A support plate 41 is attached to one end of the bottom of the wing 2. Multiple fixing rods 42 are fixedly connected to one side of the support plate 41, with one end of each fixing rod 42 fixedly connected to the bottom of the arc-shaped protective frame 43. A groove 44 is formed at the top of the support plate 41, and two positioning blocks 491 are slidably connected inside the groove 44. An L-shaped insert 492 is fixedly connected to the top of each positioning block 491. Mounting slots 493 are formed on both sides of the wing 2, with one end of each L-shaped insert 492 inserted into the mounting slot 493. The groove 44... The slide 44 is equipped with a first bidirectional lead screw 49. The two ends of the first bidirectional lead screw 49 are rotatably connected to the two sides of the inner wall of the slide 44. The two positioning blocks 491 are symmetrically threaded to the outer wall of the first bidirectional lead screw 49. A worm 47 and a worm wheel 48 are provided on one side of the slide 44. The worm 47 is located on one side of the worm wheel 48 and meshes with the worm 47 and the worm wheel 48. The worm wheel 48 is fixedly sleeved on one end of the outer wall of the first bidirectional lead screw 49. The bottom end of the worm 47 is rotatably connected to one side of the bottom of the inner wall of the slide 44. The top end of the worm 47 extends to one side above the support plate 41 and is fixedly connected to a knob 46. A protective cap 45 is provided on one side of the top of the support plate 41. An annular mounting groove is opened on one side of the top of the support plate 41. The bottom of the protective cap 45 is threaded into the inside of the annular mounting groove. The outer wall of the knob 46 is located inside the protective cap 45.

[0027] When assembling the paddle protection mechanism 4 and the wing 2 of the unmanned aerial vehicle body 1, the screw rotating knob 46 and the worm 47 are used to drive the worm gear 48 and the first bidirectional lead screw 49 to rotate. The worm 47 and the worm gear 48 have a self-locking function. The worm 47 can drive the worm gear 48 to rotate, but the worm gear 48 cannot drive the worm 47 to rotate. When the first bidirectional lead screw 49 rotates, the two positioning blocks 491 and the L-shaped insertion rods 492 can be driven to move. The two L-shaped insertion rods 492 can be inserted into the mounting sockets 493 on both sides of the wing 2. In this way, the support plate 41 of the paddle protection mechanism 4 can be fixedly installed at the bottom of the wing 2. The fixed rod 42 is arranged to facilitate the fixed connection between the support plate 41 and the arc-shaped protection frame 43. The arc-shaped protection frame 43 is arranged to protect the propeller 3 from being damaged due to collision with other objects during flight of the unmanned aerial vehicle.

[0028] Embodiment Two

[0029] As shown in Figs. 1-6 the lower part of the unmanned aerial vehicle body 1 is provided with a protection mechanism 5. The protection mechanism 5 comprises a protection cover 51. The top of the protection cover 51 is fixedly installed at the bottom of the unmanned aerial vehicle body 1. The lower part of the inside of the protection cover 51 is provided with a mounting plate 56. The top of the mounting plate 56 is symmetrically hinged with two connecting rods 55. The bottom of the mounting plate 56 is fixedly installed with a unmanned aerial vehicle holder 6. The unmanned aerial vehicle holder 6 is installed with a camera 7. The upper part of the right side of the protection cover 51 is fixedly installed with a speed reducer motor 52. The output end of the speed reducer motor 52 extends into the inside of the protection cover 51 and is fixedly connected with a second bidirectional lead screw 53. The left end of the second bidirectional lead screw 53 is rotatably connected to the upper part of the left side of the inner wall of the protection cover 51. The outer wall of the second bidirectional lead screw 53 is symmetrically threadedly sleeved with two connecting blocks 54. The top ends of the two connecting rods 55 are hinged to the bottoms of the two connecting blocks 54. The top of the inner wall of the protection cover 51 is provided with a limiting slot. The top of the connecting block 54 is slidingly connected to the inside of the limiting slot. The two sides of the inner wall of the protection cover 51 are provided with guide grooves 58. The two sides of the mounting plate 56 are fixedly connected with sliding blocks 57. The outer walls of the sliding blocks 57 are slidingly connected to the inside of the guide grooves 58.

[0030] In this embodiment, the camera 7 is arranged to perform shooting work. When the camera 7 is not needed, the speed reducer motor 52 and the second bidirectional lead screw 53 are used to drive the two connecting blocks 54 to move relative to each other. The bottoms of the two connecting blocks 54 drive the mounting plate 56 to move upward through the connecting rods 55. The two sides of the mounting plate 56 simultaneously drive the sliding blocks 57 to slide in the guide grooves 58. The sliding blocks 57 are arranged in the guide grooves 58 to guide the two sides of the mounting plate 56 and keep the stability of the mounting plate 56. The mounting plate 56 can drive the camera 7 to move into the protection cover 51 through the unmanned aerial vehicle holder 6 while moving. The protection cover 51 protects the camera 7.

[0031] In summary, as Figs. 1-6 As shown, this combined unmanned aerial vehicle (UAV) is used such that when the main body 1 is in flight, the propeller 3 is protected by the arc-shaped protective frame 43, and the camera 7 can be used for filming. When the camera 7 is not needed, the output end of the reduction motor 52 drives the second bidirectional lead screw 53 to rotate. The second bidirectional lead screw 53 drives the two connecting blocks 54 to slide relative to each other inside the limiting groove. The bottom of the two connecting blocks 54 drives the top of the connecting rod 55 to move. At the same time, the bottom of the connecting rod 55 drives the mounting plate 56, the slider 57, the UAV gimbal 6, and the camera 7 to move upward, so that the camera 7 can be moved into the protective cover 51 for protection. If it is necessary to disassemble the propeller protection mechanism 4, the protective cap 45 can be removed by bolting, and the knob 46 and the worm gear 47 can be rotated. The worm gear 47 drives the worm wheel 48 and the first bidirectional lead screw 49 to rotate. The first bidirectional lead screw 49 drives the two positioning blocks 491 to slide in the groove. The internal relative sliding of 44 allows the positioning block 491 to move one end of the L-shaped rod 492 out of the mounting socket 493, thus disassembling the blade protection mechanism 4. When installing the blade protection mechanism 4, move the support plate 41 of the blade protection mechanism 4 to one end under the wing 2, and position one end of the two L-shaped rods 492 at the mounting sockets 493 on both sides of the wing 2. At this time, rotate the knob 46 and the worm gear 47 in the opposite direction, and drive the positioning block 491 and the L-shaped rods 492 to move in the same way. One end of the two L-shaped rods 492 can be inserted into the mounting sockets 493 on both sides of the wing 2. Then, screw the bottom of the protective cap 45 into the annular mounting groove and position the protective cap 45 outside the knob 46 to protect the knob 46. The support plate 41 of the blade protection mechanism 4 can then be fixedly installed at the bottom of the wing 2, thus enabling quick disassembly and assembly between the blade protection mechanism 4 and the wing 2 of the unmanned aerial vehicle.
