The support plate 451 is arranged on the lower connecting plate 43, the column 453 is rotatably connected to the support plate 451, the driving gear 452 is sleeved on the column 453, the rotating disk 454 is arranged on one end of the column 453 away from the support plate 451, and the driving gear 452 is meshed with the inner gear ring 443 for transmission.

[0040] With such arrangement, when the seal body 2 is needed, the rotating disk 454 in the driving assembly 45 is rotated, the rotating disk 454 drives the column 453 to rotate, the column 453 in turn drives the driving gear 452 to rotate, the driving gear 452 is meshed with the inner gear ring 443, drives the inner gear ring 443 to rotate, the rotation of the inner gear ring 443 makes the gear 441 on the rotating assembly 44 rotate, the connecting column 442 on the gear 441 also rotates, the sealing blade 41 arranged on the connecting column 442 also rotates with the rotation of the connecting column 442, and then the sealing blade 41 retracts, opens the second through hole 12 provided on the lower connecting plate 43, and then the seal body 2 can be pressed to The seal body 2 is made to slide in the placement cavity 10 by hand, and slide out from the first through hole 11 and the second through hole 12 to make a seal. When the seal body 2 is not in use, the seal body 2 is put back into the placement cavity 10, and the rotating disk 454 is rotated to drive the inner gear ring 443 to rotate, and the inner gear ring 443 drives the gear 441 to rotate, and the gear 441 drives the sealing blade 41 to rotate, so that they are combined together to block the second through hole 12. Through the setting of the sealing blade 41, the driving component 45 and the rotating component 44, the seal body 2 is in a sealed state and will not be affected by external water, thereby improving the safety of the seal body 2 and also improving the service life of the seal body 2.

[0042] With such arrangement, when the seal body 2 is not in use, the first spring 5 and the second spring 6 will place the seal body 2 in the placement cavity 10. When the seal body 2 is in use, the handle of the seal body 2 is pressed to drive the seal body 2 to slide in the placement cavity 10, and the first spring 5 and the second spring 6 will stretch. When the seal body 2 is not in use, the handle of the seal body 2 is released, and the seal body 2 automatically slides into the placement cavity 10 due to the action of the spring tension, thereby improving the stability of the overall structure and improving convenience.

[0043] Optionally, in some embodiments, see Figure 4 A sealing ring 8 is provided on the seal handle 3.

[0044] With such arrangement, when the seal body 2 is used, the seal body 2 will be caught by the limiting ring on the seal body 2 handle after sliding a certain distance, thereby ensuring that the seal body 2 will not separate from the outer shell 1 and improving the safety of the seal body 2.

[0045] Optionally, in some embodiments, see Figure 4A non-slip pad 7 is provided on a side of the lower connecting plate 43 away from the upper connecting plate 42 .
