Example III
The difference between this embodiment and the second embodiment is that the inner hole of the jaw 85 is communicated with the blanking hole 81, at this time, the tongue pushing plate 8 has a U-shaped structure (as shown in fig. 7), the radial opening 82 is located at the U-shaped opening end of the tongue pushing plate 8, the blanking hole 81 and the jaw 85 are radially communicated through the side opening 83, the side opening 83 and the radial opening 82 are located at two radial sides of the jaw 85, the width of the side opening 83 is smaller than the width of the radial opening 82, and the width of the radial opening 82 is smaller than the diameter of the tongue cover 12.
In order to allow the tongue cover 12 to enter the jaw 85, the friction force between the tongue cover 12 and the upper and lower covers 11 and 13 needs to be larger than the expansion force of the radial opening 82, and the tongue pushing plate 8 is configured in a U-shaped structure to be more beneficial to the radial opening 82 of the jaw 85 to be opened, and thus the tongue cover 12 does not pass through the side opening 83 after entering the jaw 85 due to the smaller width of the side opening 83.
Preferably, the outer edge of the tongue cover 12 is provided with an annular thin edge 121, the thickness of the thin edge 121 is smaller than that of the tongue cover 12, the inner circumferential surface of the jaw 85 is provided with a concave groove 84, and when the jaw 85 clamps the tongue cover 12, the thin edge 121 is inserted into the groove 84, so that the tongue cover 12 can be prevented from falling off when clamped in the jaw 85, the surface of the tongue cover 12 can be prevented from tilting, and the sealing performance of the cover is ensured after the sampling is finished.
Example IV
In the third embodiment, when three mounting bosses 133 are provided, one of the mounting bosses 133 is located on the line connecting the claw 85 and the center of the blanking hole 81, and since the mounting boss 133 protrudes from the surface of the lower cover 13, the mounting boss 133 is at the same height as the tongue pushing plate 8, and when the width of the side opening 83 is larger than that of the mounting boss 133, the side opening 83 does not affect the translational movement of the lower cover 13.
In this embodiment, the mounting boss 133 located on the connection line between the jaw 85 and the center of the blanking hole 81 is the limiting boss 132, so that the width of the limiting boss 132 is larger than the width of the side opening 83 and smaller than the width of the radial opening 82; when the limit boss 132 comes into contact with the side opening 83, the tongue-pushing plate 8 is spread open to open the radial opening 82.
As can be seen from fig. 8 and 9, the acting force to the radial opening 82 before the tongue cover 12 enters the jaw 85 faces the inside of the jaw 85, which is unfavorable for the radial opening 82 to open, while the acting force to the radial opening 82 faces the outside of the jaw 85 when pushing out from the jaw 85, the radial opening 82 is easy to open, so that the force required by the tongue cover 12 entering the jaw 85 is larger.
Preferably, the side opening 83 is in rounded transition with the blanking hole 81 and the clamp claw 85, the outer surface of the limiting boss 132 is an arc surface aligned with the outer edge of the lower cover 13, and when the arc surface contacts with the side opening 83, the side opening 83 can be opened more easily.
