This research is about the device that the launch pad of the UAV is separated from the flying body, In particular, when the UAV is launched, the flying body can make the carrier vehicle derail naturally without external impact, so as to stably maintain the separation promotion device of the flying body from the initial posture.The specific means of this study are: on the main structure (10) of the launcher and the building (10), the carrier (12) that can move back and forth, the carrier (14) that can be separated from the carrier (12) and the lock device (16) that the carrier (12) places on the building (10),Also, stop the carrier (18) and,The traction wire rope (20) connected on the front side of the carrier (12) is connected with the acceleration device (24) through a roller (22), which is connected with the traction power cylinder (26) in a launching device,After the above-mentioned building (10), the cotton rope (30) connected to the tail of the carrier (12) on the fixed bracket (28) is reeled into the roller (32), and the bearing (34) can be rotated,Connect the drum (32) with the hydraulic motor (36),The hydraulic motor (36) is composed of a brake valve (38) which prevents the rotation of the motor (36).
