When the AGV for the transfer vehicle of the embodiment is used, the vehicle body is driven to the vehicle to be transferred through the roller 2, so that the vehicle to be transferred is located between the two bearing frames 3, namely, the two bearing frames 3 are respectively located on the left side and the right side of the vehicle to be transferred, the two clamping devices on the bearing frames 3 located on the left side are respectively used for clamping the left front wheel and the left rear wheel of the vehicle to be transferred, and the two clamping devices on the bearing frames 3 located on the right side are respectively used for clamping the right front wheel and the right rear wheel of the vehicle to be transferred. Before the clamping device clamps the wheels, the two clamping arms 24 of the clamping device are in an open state, then the clamping frame 14 is driven by the first motor 12 to slide upwards or downwards along the bearing frame 3 so as to meet the height of the clamped vehicle, then the second motor 25 is used for driving the movable frame 15 to slide horizontally along the clamping frame 14, so that the distance between the first clamping device 6 and the second clamping device 4 on the same bearing frame 3 meets the axle distance of the vehicle to be transported, then the two clamping arms 24 of the clamping device are operated by the two first electric push rods 16, the two clamping arms 24 of the clamping device are made to rotate close to each other until the two clamping arms 24 are closed, the wheels are clamped between the two clamping arms 24, after four clamping devices clamp the four wheels of the vehicle to be transported, the second electric push rods 7 are extended, the pressing plate 5 is pressed on the outer side surfaces of the wheels, then the clamping frame 14 is driven by the first motor 12 again to slide upwards along the bearing frame 3, the vehicle to be transported also moves upwards along the clamping frame 14 until the vehicle to be transported is separated from the wheels, then the two electric push rods 16 are driven by the two electric push rods 16 to rotate close to each other until the two clamping arms 24 are released from each other, the two AGV are driven by the two clamping devices to rotate along the two clamping arms 24 until the four wheels are released from each other, and then the two clamping arms are in a state of contact with the ground surface of the two AGV is released to rotate downwards, and then the second electric push rod 7 is retracted, the pressing plate 5 is separated from the wheels, and finally the AGV is driven away, so that the transportation work of the vehicle is completed. Therefore, the structure of the embodiment is simple, the first electric push rod 16 drives the clamping arm 24 to rotate through the rack 21 and the gear 22, the clamping device clamps the wheels from the left side and the right side of the vehicle accurately respectively when the vehicle is transported, and the AGV can transport the vehicle stably in the transportation process due to the fact that the vehicle is located in the middle of the whole AGV.
