[0002] The upper stage is sent into the air by using a vehicle as a carrier, and is usually composed of several stages. When the lower stage completes the work, the lower stage must be discarded to improve the carrying capacity and ensure the effective load into the air, so the interstage separation structure needs to be designed. The box-type launch vehicle separates the first stage tail cover mainly by using the engine starting thrust as the separation impulse source. The spring installed on the tail cover is used as the lateral power source of the tail cover, so that the tail cover is thrown away along the specified trajectory during the separation process. Although this separation method can realize reliable separation, the dynamic disturbance of the separation process is large, and the vibration load of the separation body is large. The spring on the tail cover is easy to be separated from the tail cover, which has the risk of impacting the vehicle, so the reliability is not high. During the working process, the spring and the card at both ends must be reliably fixed, otherwise the spring is easy to be separated to form the redundant object. The existing spring and card connection at both ends only has the whole wrapping type and the elastic sheet friction fixing type, and the spring is often separated from the tail cover during the use process.
