The invention belongs to the technical field of satellite docking equipment, and discloses a micro-nano satellite electromagnetic docking mechanism which comprises an active docking assembly and a passive docking assembly, the active docking assembly comprises a head shell, a head connecting piece, an electromagnet cylinder, a locking assembly and a positioning circular truncated cone, and the locking assembly comprises a lead screw, a locking motor and a plug pin. The screw rod is connected between the bearing of the head shell and the locking motor, the screw rod is provided with forward and reverse threads, the forward and reverse threads are in threaded connection with forward and reverse conical surface nuts, and a tension spring is connected between the two bolts; the passive butt joint assembly comprises an electromagnet, butt joint limiting teeth and a butt joint guide cylinder. The butt-joint limiting teeth are connected with an iron core of the electromagnet, the upper inclined faces of the butt-joint limiting teeth are consistent with the butt-joint guide cylinder, and the lower inclined faces of the butt-joint limiting teeth are the same as the inclination angle of the plug pin. The problems of fuel consumption, plume pollution, docking impact and the like in an existing mainstream docking method are solved, and the method is suitable for free docking combination of multiple micro-nano satellites, configuration transformation of a combination body and other scenes.
