The transmission plate 54 is installed on the transmission rod 52. Then the transmission disc 54 drives the transmission belt 55 for transmission, and the transmission disc 54 and the driven disc 49 are transmitted through the transmission belt 55. At this time, the driven disc 49 rotates and drives the locking screw 46 to rotate internally between the two locking shaft seats 45. At this time, the positive thread block 47 and the reverse thread block 48 threadedly connected to the locking screw 46 move to both sides respectively, and the screw teeth inside the positive thread block 47 and the reverse thread block 48 are opposite, so they can move in two directions.

The positive thread block 47 and the reverse thread block 48 are clamped in the clamping groove 33, and the arm installation is completed.

[0026] See also Figure 1 and Figure 6-8The two connecting components 3 on each side form a pair, and the connecting components 3 of the pair are commonly fixed with a connecting plate 9, the inner side of the connecting plate 9 is fixed with two fixing plates 10, a rotating plate 11 is rotatably connected between the two fixing plates 10, and the fixing surface 12 of the rotating plate 11 is fixed to the outer shell wall of the unmanned aerial vehicle body 1, and the bottom end of the fixing plate 10 is hinged with a secondary connecting plate 13, and the bottom end of the secondary connecting plate 13 is fixed with a vertical rod 14, the middle part of the vertical rod 14 is hinged with a horizontal plate 15, and the bottom of the vertical rod 14 is hinged with A secondary transverse plate 16, a fixing surface 17 of the transverse plate 15 is fixed on the outer shell wall of the unmanned aerial vehicle body 1, and a mutual adjustment component is connected between the secondary transverse plates 16, and the mutual adjustment component includes a setting box 18 fixed to the bottom end of the unmanned aerial vehicle body 1, and the interior of the setting box 18 is communicated with the interior of the unmanned aerial vehicle body 1, and the mutual adjustment component includes a drive motor 19 arranged inside the setting box 18, and the output end of the drive motor 19 is connected to a meshing toothed disc 20, and the meshing toothed disc 20 is meshed with two rack plates 21, and the two rack plates The ends of the rack plates 21 that are away from each other are fixed with a through rod 22 that passes through the setting box 18, and the through rod 22 is fixedly connected to the corresponding secondary transverse plate 16. A balancing sleeve 23 is sleeved on the rack plate 21, and a fixed bracket 24 is fixed on the outer wall of the balancing sleeve 23. The other end of the fixed bracket 24 is fixed to the inner wall of the setting box 18. The driving motor 19 drives the meshing toothed disc 20 to rotate, thereby driving the two rack plates 21 to move away from or towards each other, and finally drives the through rod 22 to pull the hinged vertical rod 14 to make the hinged The vertical rod 14 changes from a vertical state to an inclined state, thereby driving the auxiliary connecting plate 13 to tilt at the rotation point between the fixed plate 10 and the rotating plate 11. The auxiliary connecting plate 13 is connected to the bottom end of the fixed plate. The farther the connection position is from the rotation point of the fixed plate 10 and the rotating plate, the better the subsequent extension and contraction effect of the arm will be. The driving arm can be relatively extended and contracted. During flight, the UAV can change the cruising state to the contracted state, so as to pass through narrow spaces, and can recover from the contracted state to the cruising state, thereby ensuring the maneuverability of the UAV when encountering narrow spaces and improving work efficiency.

[0027] See also Figure 8 Four traction components are fixedly provided on the outer shell wall of the drone body 1, and the four traction components correspond to the connecting blocks 31 respectively. The traction components include a bent plate 25, and a traction slot 26 is provided on the bent plate 25. A traction rod 27 that slides through the traction slot 26 is fixedly provided on the outer wall of the connecting block 31, and a flip-type contraction is generated, so that the traction rod 27 slides in the traction slot 26, thereby ensuring the stability of the contraction or extension of the machine arm.

[0028] See also Fig. 9The camera 2 is rotatably mounted at the bottom of the setting box 18. A motor 60 is fixed at the bottom of the setting box 18. An output rod 61 is connected to the output end of the motor 60. A bending rod 62 is fixed to the other end of the output rod 61. A plug rod 63 is fixed to the bending rod 62. One end of the plug rod 63 is inserted into a bent plate 64. The bent plate 64 has an arc-shaped slide groove 65 that matches the plug rod 63. A swing rod 66 is fixed to the other end of the bent plate 64. The camera 2 is mounted at the bottom of the swing rod 66. A rotating point rod 67 is fixed at the top of the rocking arm 66, and a bearing 68 is sleeved on the top of the rotating point rod 67, and the bearing 68 is fixed at the bottom of the setting box 18. The specific motor 60 drives the output rod 61 and the bending rod 62 to rotate, thereby driving the insertion rod 63 to rotate in the arc-shaped slide groove 65, and driving the rocking arm 66 on the bent plate 64 to repeatedly swing around the bearing 68. By adjusting the swing angle of the camera 2 installed at the bottom of the rocking arm 66, or reciprocating swing, the camera 2 can complete the shooting and recording work of a wider space.

[0029] The specific installation workflow is to insert the connecting slider 42 into the interior of the connecting block 31, the transmission shaft plate 51 into the installation groove 32, and the support slider 43 into the interior of the support slide groove 34, which can enhance the stability of the two, which is beneficial to ensure the stability of the flight of the drone after the drone is launched. After the support slider 43 and the support slide groove 34 are installed in place, the locking plate 53 is manually rotated to make the transmission rod 52 rotate internally between the two transmission shaft plates 51, and the transmission plate 54 is installed on the transmission rod 52, and then the transmission plate 54 drives the transmission belt 55 to transmit, and the transmission plate 54 and the driven plate 49 are transmitted through the transmission belt 55. At this time, the driven plate 49 rotates and drives the locking screw 46 to rotate internally between the two locking shaft seats 45. At this time, the positive thread block 47 and the reverse thread block 48 threadedly connected to the locking screw 46 move to both sides respectively, and the screw teeth inside the positive thread block 47 and the reverse thread block 48 are opposite, so they can move to the two sides. The locking groove 44 and the locking slider can be used to realize the transmission of the screw rod on the one hand, and the stability of translation on the other hand. The positive thread block 47 and the reverse thread block 48 are clamped in the clamping groove 33. The machine arm is installed and in use, the camera 2 can complete the shooting and recording work. The power motor 6 installed on the machine arm assembly 4 provides the power for the drone to take off and cooperates with the blades 7 to fly in the air. The support leg 8 can play a supporting and buffering role when landing. When the use is completed and needs to be stored, the locking groove 44 can be rotated in the opposite direction, and then the locking screw 46 can be rotated through the transmission belt 55, so that the positive thread block 47 and the reverse thread block 48 threadedly connected to the locking screw 46 move toward the middle, and the clamping connection is released. At this time, after the positive thread block 47 and the reverse thread block 48 are shrunk, the width is smaller than the inner cavity of the connecting block 31, and the machine arm assembly 4 can be removed and stored. A rubber sleeve made of rubber material is set at the bottom of the support leg.

[0030] The driving motor 19 drives the meshing gear plate 20 to rotate, thereby driving the two rack plates 21 to move away from or towards each other, and finally driving the through rod 22 to pull the hinged vertical rod 14 to each other, so that the hinged vertical rod 14 changes from a vertical state to an inclined state, thereby driving the auxiliary connecting plate 13 to tilt at the rotation point between the fixed plate 10 and the rotating plate 11. The auxiliary connecting plate 13 is connected to the bottom end of the fixed plate. The farther the connection position is from the rotation point of the fixed plate 10 and the rotating plate, the better the subsequent arm extension and contraction effect is. By driving the arm to extend and contract relatively, the UAV can change the cruising state to the contracted state during flight, so as to pass through narrow spaces. It can recover from the retracted state to the cruising state, thereby ensuring the maneuverability of the drone when encountering a narrow space and improving work efficiency. By generating a flip-type contraction, the traction rod 27 slides in the traction slide groove 26 to ensure the stability of the arm contraction or extension. The motor 60 drives the output rod 61 and the bending rod 62 to rotate, thereby driving the insertion rod 63 to rotate in the arc slide groove 65, driving the rocking arm 66 on the bent plate 64 to repeatedly swing around the bearing 68, adjusting the swing angle of the camera 2 installed at the bottom of the rocking arm 66, or reciprocating swing, the camera 2 can complete the shooting and recording work of a wider space.

[0031] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
