The invention discloses an aerospace craft segment separation device which comprises a sliding cylinder (1), a separation spring (2), a sleeve (3), a sleeve fixing nut (4), a plug cover (5), a sliding rod (6) and a plug screw (7). Movement of the separation spring (2) on the normal plane of the center axis is limited through the sleeve (3), in the axial direction, the separation spring (2) is limited through the plug cover (5), the sliding rod (6) and the sliding cylinder (1), the sliding rod (6) is installed on the plug cover (5), the sliding cylinder (1) is installed on a separation section, when the separation spring (2) is released, a movable part moves relative to a fixed part and is stuck at the tail portion through threads along with release of the separation spring (2), and the plug cover (5) is moored; meanwhile, axial movement of the separation spring (2) is limited through the plug cover (5) and the separation spring (2) is moored. By means of the device, the risk that a moving object collides with an engine effuser or an upper-level instrument device can be effectively avoided, and separation reliability is improved.
