The docking joint 103 is detachably connected with a plug connector 107, and the opposite end of the plug connector 107 is fixedly connected with a connecting tube 108, and the connecting tube 108 is detachably connected with an arm body 109, and the other end of the arm body 109 is fixedly installed with a driving motor 110, and the output end of the driving motor 110 is fixedly connected with a propeller 112; it also includes a locking assembly and a docking assembly, the locking assembly is arranged between the docking joint 103 and the plug connector 107 for installation and use, and the docking assembly is installed inside the plug connector 107 and cooperates with the connecting tube 108 for installation and use.

[0030] Specifically, it should be noted that the drive motor 110 is electrically connected to the control unit through a wire, and the specific working principles therebetween are referenced through the existing technology and will not be elaborated on herein. A control unit is installed inside the drone body 1, and the control unit is electrically connected to the connector female seat 105 through a wire, and a connector male seat 302 is fixedly installed inside the plug connector 107, and then one end of the connector male seat 302 is electrically connected to the drive motor 110 through a wire. When the plug connector 107 is inserted into the docking connector 103, the connector male seat 302 inside the plug connector 107 will be inserted into the connector female seat 105, thereby facilitating the control unit inside the drone body 1 to transmit instructions to the drive motor 110.

[0031] The connector female seat 105 is composed of a crown spring female hole 5, a crown spring body 501 and a rubber sleeve 502. The connector male seat 302 is composed of a pin 503 and a rubber ring 504. The crown spring female hole 5 is internally installed with a vertical or diagonal spring sheet. The spring sheet is made of wear-resistant material, and its surface is gold-plated or silver-plated. It is interference-fitted with the connector male seat 302 to ensure its conductive reliability.

When the plug connector 107 is inserted into the docking connector 103, the limiting plate 301 will slide and insert into the docking connector 103 at the bottom of the docking connector 103, so as to increase the limit when the plug connector 107 is docked with the docking connector 103, thereby increasing the stability of the docking between the plug connector 107 and the docking connector 103, and then the connector male seat 302 inside the plug interface 3 will be inserted into the connector female seat 105 inside the accommodating chamber 104, and then the arc bent plate 307 will be rotated so that the arc bent plate 307 can be rotated. The buckle 309 on the plate 307 is moved to the upper and lower sides of the plug connector 107. First, one end of the buckle 309 is preliminarily locked with the arc groove 304 on the ear 303, and then the other end of the buckle 309 is pushed so that one side of the buckle 309 fits against the surface of the plug connector 107, thereby facilitating the docking work. When the plug connector 107 is disassembled, similarly, the buckle 309 is pulled so that the buckle 309 falls off from the surface of the plug connector 107, and then the buckle 309 is rotated around the second rotating shaft 308, so that one end of the buckle 309 is detached from the arc groove 304, and then the arc bent plate 307 is rotated to facilitate the disassembly of the plug connector 107.

Docking grooves 2 are provided on both sides of the drone body 1, and a mounting hole 201 is provided in the middle position of the docking groove 2. A mounting groove 202 is provided on the bottom surface of the drone body 1.

[0036] Specifically, when the arm body 109 on the connecting tube 108 is disassembled and replaced, the pin 403 inside the positioning hole 4 is pushed, and the pin 403 is pushed so that the pin 403 is retracted into the inside of the connecting tube 108, and a baffle 405 is fixedly connected to the pin 403, and a return spring 406 is sleeved on the pin 403, and the baffle 405 squeezes the return spring 406 by pushing the pin 403, and the docking sleeve 401 is fixedly connected to the arm body 109, and when the pin 403 is retracted into the inside of the connecting tube 108, the arm body 1 09 is pulled to facilitate the arm body 109 to be separated from the interior of the connecting tube 108, and then the arm body 109 is replaced. After the replacement is completed, the docking sleeve 401 on the arm body 109 is inserted into the interior of the connecting tube 108, and one end of the pin 403 slides on the inner wall of the connecting tube 108. When the pin 403 slides to the position of the positioning hole 4 on the connecting tube 108, the elastic force of the reset spring 406 on the pin 403 makes the pin 403 re-set to the interior of the positioning hole 4, thereby completing the installation of the connecting tube 108.

When the plug connector 107 is inserted into the docking connector 103, the limiting plate 301 will slide and insert into the docking connector 103 at the bottom of the docking connector 103, so as to increase the limit when the plug connector 107 is docked with the docking connector 103, and increase the stability of the docking between the plug connector 107 and the docking connector 103. Then the connector male seat 302 inside the plug interface 3 will be inserted into the connector female seat 105 inside the accommodating chamber 104, and then the arc bent plate 307 will be rotated to make the arc The buckle 309 on the curved plate 307 is moved to the upper and lower sides of the plug connector 107, and one end of the buckle 309 is first preliminarily locked with the arc groove 304 on the hanging ear 303, and then the other end of the buckle 309 is pushed so that one side of the buckle 309 fits with the surface of the plug connector 107, so as to facilitate the docking work. When the plug connector 107 is disassembled, the buckle 309 is pulled in the same way so that the buckle 309 and the surface of the plug connector 107 fall off, and then the buckle 309 is rotated around the second rotating shaft 308, so as to facilitate one end of the buckle 309 to be separated from the arc groove 304, and then the curved plate 307 is rotated, so as to facilitate the disassembly of the plug connector 107;

[0038] When the arm body 109 on the connecting tube 108 is disassembled and replaced, the pin 403 inside the positioning hole 4 is pushed, and the pin 403 is pushed to retract the pin 403 into the inside of the connecting tube 108.
