[0028] Embodiment 2

[0029] As Figure 1 and Figure 5 shown, the auxiliary mechanism 3 includes a concave seat 31. Both ends of the concave seat 31 are fixedly installed with first long plates 32, and one side of the concave seat 31 is fixedly installed with a second long plate 33. The lower ends of the two groups of first long plates 32 and the second long plate 33 are all fixedly installed with hexagonal support seats 34. The lower ends of the three types of hexagonal support seats 34 all penetrate the barrel cover 12 and are fixed to the upper end of the sealing plate 25. The inner wall of the concave seat 31 is fixed to the outer wall of the toothed plate 23.

[0030] The overall effect achieved by this embodiment is that by providing the auxiliary mechanism 3, when the toothed plate 23 moves downward, the toothed plate 23 drives the concave seat 31 to move downward, the concave seat 31 drives the two groups of first long plates 32 and the second long plate 33 fixed thereto to move downward, and the two groups of first long plates 32 and the second long plate 33 both drive the hexagonal support seats 34 fixed thereto to move downward. The three hexagonal support seats 34 push the sealing plate 25 downward, thereby increasing the stability when the sealing plate 25 moves downward.

[0031] Usage method and working principle of this device: First, cover the barrel cover 12 on the barrel head 11, and then, through the fixing component 13, the barrel cover 12 can be fixed on the barrel head 11. Then, by rotating the disc 211, the disc 211 drives the threaded rod 29, and one end of the threaded rod 29 rotates inside the turntable 22. The threaded rod 29 also drives the gear 210 to rotate. Under the meshing cooperation of the gear 210 and the toothed plate 23, the gear 210 drives the toothed plate 23 to move downward, so that the toothed plate 23 passes through the barrel cover 12 and pushes the sealing plate 25 to move downward. And the sealing plate 25 drives the first sealing ring 24 and the second sealing ring 28 to move downward, so that the first sealing ring 24 and the second sealing ring 28 are respectively inserted into the first sealing circular groove 26 and the second sealing circular groove 27, which can seal the barrel head 11 and the barrel cover 12. At the same time, it can also apply pressure to the sealing plate 25 to improve the sealing performance between the first sealing ring 24 and the second sealing ring 28 and the first sealing circular groove 26 and the second sealing circular groove 27. Then, insert the locking rod 212 into the locking hole 213, and further, the threaded rod 29 can be fixed inside the turntable 22, which can limit the gear 210 to prevent the toothed plate 23 from driving the gear 210 to rotate. Finally, when the toothed plate 23 moves downward, the toothed plate 23 drives the concave seat 31 to move downward, and the concave seat 31 drives the two groups of first long plates 32 and the second long plates 33 fixed thereto to move downward. And the two groups of first long plates 32 and the second long plates 33 both drive the hexagonal support seats 34 fixed thereto to move downward. The three hexagonal support seats 34 push the sealing plate 25 to move downward, which can increase the stability when the sealing plate 25 moves downward.
