the clockwise rotation of the blade 62 in the corresponding side connection slot 14 can be embedded in the side connection slot 14, and the counterclockwise rotation of the blade 62 in the side connection slot 14 can limit the angle of the blade 62 through the side connection slot 14.
Specifically, when the inner slip ring 41 continuously descends, the sealing film 42 at the bottom end of the inner slip ring 41 contacts with the blade 62, at this time, the blade 62 breaks the tightness of the sealing film 42 to cause the colloidal caulking agent 43 inside the sealing film 42 to flow out and fill up the experiment board, and as the inner slip ring 41 continuously descends, the bottom end of the inner slip ring 41 applies pressure to the blade 62, so that the blade 62 rotates clockwise on the transverse shaft 61 until the inner slip ring 41 is completely embedded in the side connecting groove 14 and is not blocked any more from descending, during this process, the interface generated by the blade 62 on the sealing film 42 continuously increases, thereby accelerating the speed of the colloidal caulking agent 43 flowing out, when the inner slip ring 41 descends below the side connecting groove 14, at this time, the inner slip ring 41, the base cylinder 1, the outer rubber ring 12, the inner cylinder 2 and the inner rubber ring 25 jointly form a relatively sealed annular space, and as the inner slip ring 41 continuously descends, the pressure in the annular space continuously increases, thereby the colloidal caulking agent 43 distributed on the experiment board continuously descends to the left and right of the side connecting groove 14, the interface generated by the blade 62 on the sealing film 42 continuously increases, thereby the inner cylinder 2 and the inner cylinder 25 are mounted in the gap between the inner rubber ring 12 and the inner rubber ring 25, and the top end of the experiment tube 2 can be sealed by the sealing tube 2.
Further, when the tension spring 63 at one end of the blade 62 is sleeved on the lower fastener 65, the end of the blade 62 located inside the base barrel 1 is at an angle capable of piercing the sealing film 42, and when the disposable caulking unit 4 needs to be replaced, the tension spring 63 can be fastened on the upper fastener 64, so that the blade 62 rotates to be folded into the side connecting groove 14, and the inner slip ring 41 is not blocked by the blade 62 in the process of being adsorbed by the bottom end magnet 24 of the lower limiting ring 23.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
