Before the missile is launched, reliable butt joint between the drop plug and the missile needs to be ensured; when the missile is launched and separated, the reliable separation between the falling plug and the missile is realized. Whether the drop plug can be reliably and safely separated is directly related to the safety of missile launching.

The missile fixing device is a mechanical device in the guide rail launching device for restricting the course movement of the missile and safely releasing the missile during the launching of the missile.
