On-orbit dragging-off tool and on-orbit dragging-off structure for case in space station cabin

The invention relates to the technical field of manned aerospace system equipment, and discloses an in-orbit dragging-off tool and an in-orbit dragging-off structure for a case in a space station cabin. The guide groove is formed in an equipment case in the space station cabin, the threaded hole base assembly is arranged on the equipment case in the space station cabin, the rocking handle assembly is rotationally connected to the threaded hole base assembly, and the equipment case in the space station cabin can linearly move front and back through cooperation of the guide rail and the guide groove. The problems that in the prior art, force application is limited, operation is asynchronous, the stability and reliability of the inserting and separating process are low, and the on-orbit maintainability is poor are solved. 本发明涉及载人航天系统设备技术领域，公开了一种空间站舱内机箱在轨拖离工具及在轨拖离结构，一种空间站舱内机箱在轨拖离工具，包括导轨、设于空间站舱内设备机箱上的导槽、设于空间站舱内设备机箱上的螺纹孔底座组件、转动连接于所述螺纹孔底座组件上的摇柄组件，空间站舱内设备机箱能通过导轨与导槽的配合做前后直线移动。本发明解决了现有技术存在的施力有限、操作不同步、插合和分离过程的稳定性低、可靠性低及
