At this time, the bottom end of the support plate is placed at the inner bottom end of the inner groove and will not move out of the inner groove at will, which is convenient for aligning the mesh and the hook mechanism, and also achieves the effect of conveniently moving the support plate.

[0017] 3) Turn the handle, the handle drives the screw to rotate, the screw rotates along the catheter thread, so that the screw drives the bottom block to move up and down, and the bottom block drives the hook mechanism to insert into the mesh, thereby realizing the operation of the hook mechanism.

[0035] The first sealing gasket 303 is attached to the side wall of the baffle 301, and then the nut 302 is screwed into the side wall of the baffle 301 so that the nut 302 presses the first sealing gasket 303 against the side wall of the baffle 301, and then the baffle 301 is attached to the side wall of the hull 1 so that the first sealing gasket 303 is in contact with the side wall of the hull 1, so that the baffle 301 covers the opening 6 at this time, and the hook mechanism 5 is aligned with the mesh 209. At this time, the handle 401 is turned, and the handle 401 drives the screw 402 to rotate, and the screw 402 rotates along the thread of the conduit 304, so that the screw 402 drives the bottom block 403 to move up and down, and the bottom block 403 drives the hook mechanism 5 to be inserted into the mesh 209, thereby realizing the convenient driving of the hook mechanism 5.

[0036] Reference Figure 1-8 The hook mechanism 5 includes a mounting block 501, a round shaft 502, a torsion spring 503, a hanging plate 504, a bottom plate 505 and a rotating hole 506. The side wall of the bottom block 403 is connected with multiple groups of mounting blocks 501. The side wall of the mounting block 501 is provided with a rotating hole 506. The side wall of the rotating hole 506 is rotatably connected with the round shaft 502. The side wall of the round shaft 502 is connected with the hanging plate 504. The side wall of the round shaft 502 is connected with the torsion spring 503.

The bottom end of the mounting block 501 is flush with the bottom end of the bottom block 403, and the sum of the lengths of the two hanging plates 504 and the bottom block 403 is greater than the side length of the mesh 209.

[0037] The screw rod 402 is rotated, and the screw rod 402 drives the bottom block 403 to move toward the mesh 209, and the bottom block 403 drives the bottom plate 505 to move toward the mesh 209. At the same time, the torsion spring 503 pulls the round shaft 502 to rotate upward by utilizing the elastic force of the torsion spring 503, so that the round shaft 502 drives the hanging plate 504 to rotate upward, so that the hanging plate 504 is in an upward tilted state.

After the hanging plate 504 completely passes through the mesh 209, the elastic force of the torsion spring 503 is used to restore the hanging plate 504 to its original position. When the hook 504 is pulled away from the circular shaft 502, the end of the hanging plate 504 away from the circular shaft 502 will be located outside the mesh 209, and the screw rod 402 is rotated in the opposite direction to make the hook mechanism 5 return along the original path of the mesh 209. Since the side wall of one end of the hanging plate 504 is located outside the mesh 209, the hanging plate 504 will be blocked by the side wall of the supporting plate 208 facing away from the hull 1, so that the hanging plate 504 presses the torsion spring 503 through the circular shaft 502, thereby realizing the hanging plate 504 and the supporting plate 208 facing away from the hull 1. The side walls are tightly squeezed, so that the hanging plate 504 pushes the support plate 208 to move toward the surface of the hull 1, so that the baffle plate 301 and the support plate 208 clamp the surface of the hull 1. At the same time, the top side wall of the bottom block 403 abuts against the second sealing gasket 305 to seal the conduit 304, and the baffle plate 301 and the surface of the hull 1 press the first sealing gasket 303 to further seal the contact between the baffle plate 301 and the surface of the hull 1, thereby achieving a convenient sealing effect of the opening 6.
