[0004] The above-mentioned "a drone that can be quickly disassembled and assembled" still has some disadvantages. For example, when the existing drone forearm is in use, there will be a harness running through the forearm. The harness may be used to connect the drone control board, motor, electric regulator and other internal and external devices to achieve the transmission of drone control signals, power supply and other data exchange. The harness working in a high temperature environment may cause aging, oxidation or short circuit, thereby affecting the safety and performance of the drone. At the same time, the harness is installed in the forearm bracket. If the harness needs to be disassembled for inspection, the entire forearm needs to be disassembled, which is more cumbersome.
