The invention discloses a UAV (Unmanned Aerial Vehicle) catapult-assisted take-off device, belonging to the technical field of lightweight aviation aircrafts. According to the device, high-pressure gas is adopted as a power source, and an air cylinder-pulley block type catapult propulsion manner is adopted, so that the traction force is large and is convenient to adjust; pulley blocks can be used for amplifying traction speed of an air cylinder in a multiplied manner, so that UAVs can obtain relatively high launching speed, and meanwhile, the length of a sliding rail is reduced; the launch angle of the UAV catapult-assisted take-off device is adjusted through two groups of worm gear-worm structures, and the adjustment on pitch angle and left-and-right deflection angle can be completed simultaneously, so that the adjustment of UAV launch angle is more flexible, and UAV launching is more accurate; the UAV catapult-assisted take-off device is simple in structure, easy in manufacturing, convenient in assembling and mounting and convenient in transportation; the device is good in structural stiffness, high in reliability and long in service life, the UAV catapult-assisted take-off device is used for launching the UAVs through being fixedly mounted on a platform or mounted on a launch vehicle, and thus, the application is more extensive.
