Multi-rotor aircraft for power line inspection

The invention provides a multi-rotor aircraft for power line inspection. The multi-rotor aircraft comprises a 24-hole-site rack, cantilevers or multifunctional obstacle avoidance blocks are evenly distributed in the circumferential direction of the 24-hole-site rack, the free ends of the cantilevers are connected with a rotatable motor support through cross arms, the upper end of the rotatable motor support is connected with flying blades through a flying motor, the lower end of the rotatable motor support is connected with wind driven generator blades through a wind driven generator, and driving mechanisms are arranged in the cross arms and the rotatable motor support; the cantilevers or the multifunctional obstacle avoidance blocks are connected with a Morse taper hole through fixing screws, the lower portion of the 24-hole-site rack is provided with an exit control hole communicated with the tail portion of the Morse taper hole, and the exit control hole matches an exit key to be used for pushing out the c
