The invention belongs to the technical field of satellite release, and discloses a micro-satellite on-orbit release device which comprises a frame body, launching sleeves, a position adjusting cam shaft, a rotating motor, a limiting plate, a pico-nano satellite, memory alloy pins and a sleeve cover plate. The position adjusting cam shaft and the rotating motor both penetrate through the frame body, and each launching sleeve is provided with a connecting cylinder and an arc-shaped part; the position adjusting cam shaft is provided with a cam protrusion, the connecting cylinder is arranged on a side connecting rod of the rotating motor in a penetrating mode, the arc-shaped part abuts against the cam protrusion, a hinge piece is connected between the two launching sleeves, the limiting plate is connected to the upper end of the frame body, memory alloy pins are connected to the peripheries of the launching sleeves, and first springs are connected to the memory alloy pins; and the bottom of the pico-nano satellite is connected with a second spring, the sleeve cover plate is connected to the upper parts of the launching sleeves. The device solves the problem that a satellite release device in the prior art cannot adjust the launching direction of pico-nano satellite in networking operation, and is suitable for release of micro-satellites.
