The pedal of the operating mode is far away from the hook, so that the possibility that an operator is swept by the tail end of the elastic rope is greatly reduced, and the safety of ejection operation is improved. However, this prior art does not specifically describe the connection relationship between the pedal and the wire cable, and it can be seen from the drawings of this prior art that the wire cable between the pedal and the hook is in a tensioned state, that is, the position of the pedal is still limited by the position of the hook, and it is more difficult to keep the wire cable between the pedal and the hook in a tensioned state to fall back. In addition, as a part of the releasing device, after the prior art hook is operated by the steel wire rope, the hook groove matched with the prior art hook is released, and the ejection pulley frame connected with the elastic rope is connected with the hook groove. What operate release promptly releases is ejection pulley yoke in fact, and not the direct release bungee, and the result is that this prior art unmanned aerial vehicle catapult needs extra ejection pulley yoke, and the structure is complicated, and is bulky, be not convenient for carry and assemble, and the spare part is many, and the reliability is poor, and it is very inconvenient to use.
