s2, driving the connecting rings (223) by the two ends of the sprint belt (224) in the separation process, driving the connecting cylinders (221) by the connecting rings (223), enabling the connecting cylinders (221) to rotate under stress, and driving the other connecting cylinders (221) to rotate by the connecting cylinders (221) rotating through the transmission rod (121);

s3, the connecting cylinder (221) at the bottommost part is matched with the through groove (212) in the bottom supporting plate (211) after rotating, at the moment, the connecting cylinder (221) at the bottom falls on the bottom of the mounting cavity (111), meanwhile, the connecting cylinder (221) at the penultimate part rotates to be matched with the through groove (212) in the top supporting plate (211), and at the moment, the supporting plate (211) at the penultimate part falls on the bottom supporting plate (211).
