[0028] See also Figure 1-5The limiting part 4 also includes two semicircular connecting blocks 40, a sealing gasket 410 and a connecting plug 42. The two semicircular connecting blocks 40 are movably sleeved on the outer circumferential surface of the straight rod 30 at the same time.

The use of the straight rod 30 makes the sliding of the special-shaped piston 32 more convenient.

[0029] The specific implementation process of the utility model is as follows: when using it, the hand-held soft pad 11 on the bottle body 1 is held, and then the staff rotates the first twisting block 21 on the top cover 2. The rotation of the first twisting block 21 separates the top cover 2 from the bottle body 1. After the separation is completed, the sample is placed inside the bottle body 1, and then the top cover 2 is twisted to the top of the bottle body 1 to seal it. At this time, the bottom sealing block 5 seals the bottom of the bottle body 1 to complete the preservation of the sample;

[0030] When the sample needs to be taken out, the staff rotates the second twisting block 51 on the bottom sealing block 5 to unscrew the bottom sealing block 5, and then presses the pressing head 31 on the piston part 3. The pressing of the pressing head 31 causes the straight rod 30 to slide, and the sliding of the straight rod 30 causes the special-shaped piston 32 to slide. During the sliding process, the special-shaped piston 32 first punctures the film sealing sheet 22 through the puncture head 33, so that the bottle body 1 is connected with the cavity in the top cover 2. Then, the sliding of the special-shaped piston 32 generates downward pressure to send the sample inside the bottle body 1 out. The sent sample is filtered for sediment through the filter screen 13. During the downward pressing process of the piston part 3, the round scraper 34 thereon scrapes off the sample remaining on the inner wall of the bottle body 1 to reduce the sample residue.

[0031] Furthermore, before the straight rod 30 is used, the two pulling blocks 41 on the semicircular connecting block 40 are pulled, and the pulling of the pulling blocks 41 separates the two semicircular connecting blocks 40. At this time, the soft plug 43 is squeezed and deformed by one of the semicircular connecting blocks 40, thereby passing through the interior of the semicircular connecting block 40. At this time, due to the pulling of the pulling blocks 41, the two semicircular connecting blocks 40 hinged to each other are separated, and when the semicircular connecting block 40 is fixed on the straight rod 30, it can effectively prevent the straight rod 30 from being accidentally touched, and the sealing gasket 410 at the bottom of the semicircular connecting block 40 can assist in connecting the straight rod 30 with the top of the top cover 2, thereby improving its safety in use.
