AUV (Autonomous Underwater Vehicle) underwater laying and recycling mechanism

The invention discloses an underwater laying and recycling mechanism for an AUV (Autonomous Underwater Vehicle), and belongs to the technical field of AUV recycling. The AUV underwater laying and recycling mechanism comprises a base and at least one pair of embracing arms arranged on the base, the base is further provided with a driving device used for driving the embracing arms to be opened and closed, each embracing arm is provided with at least two sets of limiting pieces used for being arranged in the circumferential direction of the AUV to limit the radial direction of the AUV at intervals in the extending direction of the embracing arm, and after the two embracing arms in the same pair are folded, the limiting pieces are arranged on the same pair of embracing arms. The space defined by the at least four sets of limiting pieces used for making contact with the AUV forms a containing space used for containing the AUV, and each embracing arm is provided with an adjusting structure used for adjusting the di
