In order to improve the clamping effect of the oxygen cylinder, the number of fixing blocks 21 in the vertical direction can be increased.

[0048] The second grid plate 2 is connected with a float 23, which can be made of rubber and is used to connect the hoist rope of the winch. The arrangement of the float 23 increases the contact area between the cage and the water, thereby improving the stability of the cage in the water and preventing the cage from shaking left and right and turning over.

The threaded rod 16 group limits the L-shaped pull block 15 to freely detach from the second grid plate 2 outward through the screw sleeve 17, so that the L-shaped pull block 15 cooperates with the stepping platform to clamp the second grid plates 2 on both sides, restricting the free movement of the second grid plates 2, thereby improving the installation stability of the second grid plates 2. The second grid plates 2 on both sides clamp the stepping platform, so that the adjacent pedals 3 fit tightly and are not easy to be separated freely, thereby improving the splicing stability of the stepping platform, restraining each other, and having high structural stability, and not easy to fall apart freely.

[0062] (e) A connecting rope 20 is passed through the barrier rod 7, and then the connecting rope 20 is wound and connected with the threaded rod 16. The barrier rod 7 and the threaded rod 16 are tied together by the connecting rope 20, which limits the free sliding of the barrier rod 7 and improves the installation stability of the barrier rod 7. It prevents the barrier rod 7 from falling off the lower protrusion 4 and causing the first grille plate 1 to fall off the pedal 3. The operation is easy and the connecting rope 20 is also easy to untie, replacing the fixing method of welding or bolting, which is simple and convenient.
