The invention relates to the technical field of tractor auxiliary devices, in particular to an electric hook of an airport tractor, which comprises a traction bolt seat and a sliding plate. A vertical guide rail is arranged on the traction bolt seat, the sliding plate is slidably connected to the traction bolt seat through the guide rail, and an electric push rod capable of driving the sliding plate to reciprocate up and down is fixedly arranged on the traction bolt seat; a first horizontal limiting plate and a second horizontal limiting plate are fixedly arranged on the side, facing the sliding plate, of the traction bolt base, the first limiting plate and the second limiting plate are vertically arranged in a spaced mode, a first through hole is formed in the first limiting plate, and a second through hole right opposite to the first through hole is formed in the second limiting plate; a vertical plug pin is connected to the sliding plate, the plug pin right faces the first through hole and the second through hole and can sequentially penetrate through the first through hole and the second through hole, and the length of the plug pin is larger than the spacing distance between the first limiting plate and the second limiting plate. The electric hook is simple in structure and accurate and reliable in action.
