the unmanned aerial vehicle is moved to the position above an object to be carried, a second motor (33) switch is started firstly, an output shaft of the second motor (33) drives a rotating shaft (34) to rotate, the rotating shaft (34) is connected through transmission to drive two rotating rods (32) to rotate simultaneously, the rotating rods (32) drive a pulling plate (35) to move through threaded connection with the pulling plate (35), the pulling plate (35) drives supporting legs (21) to change angles through rotating connection with the supporting legs (21), and then the supporting legs (21) on two sides are driven to open angles;
when an object moves between the two supporting legs (21), the supporting legs (21) enable the object to be positioned between the two supporting legs (21) through the action of the two push plates (24) and the supporting springs (28), and therefore the pull rod (7) can move downwards conveniently;
simultaneously, a first motor (5) is started to be switched on and switched off, an output shaft of the first motor (5) is connected with a belt through four belt pulleys in a transmission way to drive four screw rods (4) to rotate simultaneously, the rotating screw rods (4) are connected with the connecting block (6) in a threaded way to drive the connecting block (6) to move, the connecting block (6) drives the pull rod (7) to move downwards, and the pull rod (7) is arranged below an object;
when cardboard (9) contacts with the object cardboard (9) through the rotation with positioning seat (8) be connected thereby form the angle change, buffer spring (11) promote cardboard (9) through fixed block (10) and reset when cardboard (9) move to the object below, then first motor (5) reversal, pivoted screw rod (4) drive cardboard (9) rebound through pull rod (7), cardboard (9) support the object under the effect of fixed block (10), make the object place and move on cardboard (9);
when the object moves in standing groove (2) and promotes buffer board (12) and removes, buffer board (12) drive rack (17) through movable block (13) and remove, rack (17) drive gear (18) rotate, gear (18) move through the drive ejector pin (14) with the intermeshing of ejector pin (14), ejector pin (14) drive push rod (15) and splint (16) carry out the centre gripping fixed to the object, when being directed against different volume objects, rotate and change board (22), change board (22) and drive push rod (15) through the threaded connection with push rod (15) and remove, and then adjust splint (16) to the position of object centre gripping.
