This invention discloses a connector and a detachable amphibious
robot, comprising: a first mounting base and a second mounting base, wherein the first mounting base is provided with a guide rail, and the second mounting base is provided with a guide block that matches the guide rail; and a rotating disk, which is rotatably disposed at the top of the first mounting base, and the rotating disk is provided with a plurality of stop blocks, with a gap between adjacent two stop blocks, and the stop blocks are used to prevent the guide block from disengaging from the top of the guide rail; wherein, the rotating disk is used to rotate under pressure to a first position and a second position when the second mounting base moves up and down relative to the first mounting base, and in the first position, the guide block matches or disengages from the guide rail through the gap, and in the second position, the stop blocks correspondingly prevent the guide block from disengaging from the guide rail.
