The fixing device 6 is a horseshoe-shaped (i.e., "C"-shaped) shell, and the interior is divided into a tank A11 and a tank B14 arranged up and down through a partition 13. The tank A11 is located above the tank B14. The inner surface of the fixing device 6 is an open structure (that is, the inner surface is open). The fixed plate 12 is movably accommodated in the tank body A11 in a radial direction, and can move relative to the partition plate 13. The fixed plate 12 is in a horseshoe shape (i.e., “C” shape), and a plurality of springs C15 for reset are evenly distributed between the outer surface and the bottom surface of the tank body A11. One end of each spring C15 is connected with the outer surface of the fixed plate 12, and the other end is fixedly connected with the groove bottom surface of the tank body A11. The upper surface of the fixed plate 12 is fixedly equipped with a support B9, the support B9 is provided with a plurality of fixed rollers 10 fixed to the upper end of the sampling bottle 26;

The connecting block 19 is a rubber block, and two adjacent splints 20 are connected by a spring E24. The number of push plate 17, connecting block 19 and splint 20 is equal, and the end faces are all arc-shaped. When the splint 20 wraps the sampling bottle 26 horizontally, the sampling bottle 26 will not only shake due to the interference of the sea environment, but also rotate in a random direction; therefore, after each splint 20 clamps the sampling bottle 26, because the connecting block 19 is a rubber block with good elasticity and deformation ability, each splint 20 will convert the torque to the spring E24 when receiving the torque generated by the rotation of the sampling bottle 26, thereby realizing the absorption of the rotational torque of the sampling bottle 26 and slowing down the sampling bottle. The rotation angle and strength of 26 make the sampling bottle 26 slowly and slightly rotate to protect the safety of the sampling bottle 26.
