The invention relates to the technical field of unmanned aerial vehicles, in particular to a surveying and mapping unmanned aerial vehicle which comprises a contraction assembly used for storing a rotor wing into a notch, the contraction assembly comprises two belt pulley sets symmetrically mounted on the surface of a mounting block, and driving teeth are fixedly mounted at the upper ends of the belt pulley sets; the top ends of the driving teeth are rotationally connected with the inner wall of the machine body through limiting rods, round rods are arranged on one sides of the driving teeth, and tooth grooves are formed in the surfaces of the round rods; two groups of connecting rods are symmetrically mounted on the inner sides of the protective plates, transverse plates are fixedly connected to the tail ends of the two groups of connecting rods, round holes are formed in the sides, close to the mounting blocks, of the transverse plates, inserting rods are inserted into the round holes, and balls are fixedly mounted at the tail ends of the inserting rods. Through cooperative use of all parts, when the unmanned aerial vehicle breaks down, the rotors can be stored, the collision strength between the unmanned aerial vehicle and the ground is relieved, and the purposes of protecting the unmanned aerial vehicle and prolonging the service life are achieved.
