[0022] Through the above technical scheme, the fixing plate 5 can drive the connecting plate 4 to move up and down, and then the connecting plate 4 can drive the slide cylinder 3 and the connecting rod 7 to move up and down. The movement of the connecting rod 7 can drive the sealing ring 8 to move up and down. When the device is not in use, the slide cylinder 3 of the fixed cylinder 2 can be combined to reduce the overall volume of the device, thereby facilitating the storage of the entire device, which is beneficial to practical application and operation.

[0024] Through the above technical solution, the movement trajectory of the fixed cylinder 2 can be ensured by the coordinated use of the slider 16 and the second slide groove 17.
[0025] Specifically, both ends of the inner wall of the base 1 are provided with a slide groove 11, the interior of the slide groove 11 is slidably connected with a slide rod 12, and the end of the slide rod 12 away from the end is fixedly connected with a support plate 13.

[0027] Specifically, both sides of the slide rod 12 are fixedly connected to the limiting blocks 15, and both sides of the inner wall of the slide groove 11 are provided with limiting grooves 14 used in conjunction with the limiting blocks 15, and the limiting blocks 15 are slidably connected to the inside of the limiting grooves 14.
[0028] Through the above technical solution, the movement trajectory of the slide bar 12 can be further guaranteed by the limiting block 15 and the limiting groove 14 .
