The invention provides a multi-rotor unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises a vehicle body shell andan inserting shaft. The outer side surface of the vehicle body shell is fixedly connected with a telescopic rod, one end of the telescopic rod is fixedly connected with a case, a micro motor is arranged in the case, and the output end of the micro motor is fixedly connected with a transmission shaft; and an inserting hole is formed in the top end of the transmission shaft, and L-shaped limiting grooves are formed in the left and right side surfaces of the inner wall of the inserting hole. Through cooperative arrangement of the L-shaped limiting grooves and a threaded column, the inserting shaft is inserted into the inserting hole in the top end of the transmission shaft so that a limiting column slides in the L-shaped limiting grooves, the top end of the transmission shaft pushes a compression positioning spring plate upwards, and when the limiting column slides to the bottoms of the L-shaped limiting grooves, the inserting shaft is rotated to enable the limiting column to move into the sliding groove in one side of the L-shaped limiting grooves; and the inserting shaft is loosened, under the pressure effect of the positioning spring plate, the position of the inserting shaft is limited and fixed, and the unmanned aerial vehicle is convenient to disassemble and assemble.

    本发明提供一种多旋翼无人机,属于无人机技术领域,该多旋翼无人机包括机身外壳和插接轴,机身外壳的外侧面固定连接有伸缩杆,伸缩杆的一端固定连接有机箱,机箱的内部设置有微型电机,微型电机的输出端固定连接有传动轴,传动轴的顶端开设有插接孔,插接孔内壁的左右两侧面均开设有L形限位槽。通过L形限位槽和螺纹柱之间的配合设置,将插接轴插接至传动轴顶端的插接孔内部,使限位柱在L形限位槽内滑动,让传动轴顶端向上推动压缩定位弹簧板,使限位柱滑动至L形限位槽底部时,转动插接轴使限位柱移动到L形限位槽一侧的滑槽内部,松开插接轴,在定位弹簧板的压力作用下,对插接轴进行位置的限制固定,使该无人机便于拆装。
