The invention provides a modular low-impact linkage type microsatellite separating unit which comprises a launching guide module, a locking module, a pre-tightening module and a release module which are installed on a bottom plate. One end of the pre-tightening module is connected with the locking module through a pressing rod, the other end of the pre-tightening module is connected with the release module through a pull rope, and a linkage mechanism is formed. The separating unit is composed of a plurality of modular units and is simple and compact in structure, and all degrees of freedom of a fixed object are completely limited. In addition, the linkage mechanism is formed by the locking module, the pre-tightening module and the release module, and motion transfer is smooth and convenient. A grooving bolt is expanded to be broken through the release module based on shape memory alloy, so that impacts on microsatellites in the release process are extremely small, and no influence is generated on the posture and stability control over a spacecraft body and separated objects.
