[0055] like Figure 8 As shown, the driving motor 31 is connected to the rotating member 3 via the driving shaft 311, and the rotating member 3 is connected to the inside of the housing 1 via the rotating seat 34;

[0056] like Fig. 9 As shown, the release device 4 is provided with a control member 44 inside, and a control rod 1 441 is provided above the control member 44.

[0061] Basic principles of the present invention:

[0062] Extraction process:

[0063] like Fig.14 As shown, the driving motor 31 drives the rotating member 3 to rotate, and the rotating member 3 drives the micro-satellite 2 adsorbed by the adsorption member 321 to rotate, and the micro-satellite 2 moves along the limiting groove 111 to compress the elastic buckle 114. As the micro-satellite 2 moves, the micro-satellite 2 compresses the block 432 until the micro-satellite 2 enters the inside of the release device 4. At this time, the block 432 is restored under the action of the elastic rod 433, and the side of the micro-satellite 2 is limited. The elastic buckle 3 42 inside the release device 4 limits the bottom surface of the micro-satellite 2;

[0064] like Fig.15As shown, the micro satellite 2 inside the storage slot 11 will move to one side under the drive of the push plate 112, waiting to be captured by the subsequent adsorption member 321;

[0065] Detection phase:

[0066] like Fig.16 As shown, the detection member 13 drives the detection rod 131 to extend, and drives the detection head 132 to move toward the direction of the release device 4 until the connector 134 is inserted into the power interface 22. The internal circuit of the micro-satellite 2 is detected by the detection head 132 to ensure the stable operation and data transmission of the micro-satellite 2; with the movement of the detection head 132, the control board 142 is driven to move to one side through the push plate 133, the spring 141 is compressed, and the push plate 14 is restricted by the baffle 1 43;

[0067] Release phase:

[0068] like Fig.17 As shown, when the rotating member 3 carries the micro-satellite 2 into the release device 4, the rotating member 3 will compress the push member 152, the elastic rod 3 153, the spring 2 151, and the push plate 3 15 is restricted by the baffle 2 46 and cannot move;

[0069] like Fig.18 As shown, when the micro-satellite 2 passes the inspection, the control member 44 drives the control rod 1 441 to move upward, squeezes the push block 45, extends the telescopic tube 452 through the hydraulic channel 451, drives the baffle 2 46 to move to one side, compresses the elastic rod 5 462, and the baffle 2 46 loses the restriction on the push plate 3 15. The spring 2 151 extends, drives the push plate 3 15 to move downward, compresses the elastic buckle 3 42, pushes the micro-satellite 2 out of the inside of the release device 4, and releases the micro-satellite 2 to the predetermined orbit;

[0070] Abandonment stage:

[0071] like Fig.19 , Fig. 20 As shown, when the microsatellite 2 in the release device 4 fails the inspection, the control member 44 drives the control rod 2 442 to extend, drives the connecting rod 434 to move downward, causes the baffle 1 43 and the lifting plate 431 to move downward, and the push plate 2 14 loses the restriction of the baffle 1 43, and the side of the microsatellite 2 loses the restriction of the block 432 on the lifting plate 431; the spring 141 extends, drives the push plate 2 14 to move to one side, and pushes the microsatellite 2 in the release device 4 to the side, and the microsatellite 2 will enter the inside of the discarding groove 12 along the limiting groove 111, and the microsatellite 2 that fails the inspection will be restricted in the inside of the discarding groove 12 by the elastic buckle 2 121, so as to facilitate the recovery of the discarded microsatellite 2 when the subsequent launch vehicle returns;

[0072] Then the detection member 13 drives the detection head 132 to recover, and the push plate 14 recovers under the action of the elastic rod 143; the control member 44 drives the control rod 442 to recover, and drives the baffle 1 43 and the lifting plate 431 to move upward; waiting for the subsequent rotating member 3 to grab the micro satellite 2;

[0073] By repeating the above movements, the extraction, detection, release and recovery of the microsatellite 2 can be completed, and while satisfying the detection of the microsatellite 2 before launch, qualified microsatellites 2 can be released and unqualified microsatellites 2 can be recovered.
