摘要： The invention relates to the technical field of aircraft delivery, and discloses a delivery device, a set of delivery assembly and an aircraft. The delivery device includes a mounting part (1), a biasing part (2) and a blocking part (3). The mounting part (1) is provided with a mounting slot (11) of which the opening extends upward. The object to be delivered (100) can be hooked into the mounting slot (11). The biasing part (2) is configured to deform under the gravity of the object to be delivered (100) when it is lifted, which resets to drive the object to be delivered (100) out of the mounting slot (11) when the object to be delivered (100) falls to the ground. The blocking part (3) is configured to seal the opening of the mounting slot (11) when the object to be delivered (100) is not lifted and to open the opening of the mounting slot (11) when the object to be delivered (100) is lifted. The delivery device can realize the automatic dropping of the object to be delivered (100). It can limit the position of object to be delivered (100) which is prevented to fall out of the mounting slot (11). It can open the opening of the mounting slot (11) after lifting to enable the automatic unhooking of the object to be delivered (100) after they fall to the ground, which makes the delivery device easy to use and efficient in transporting the to-be-dropped object.
