When the sealing element 256 is combined with the switch valve pipeline, the switch valve pipeline is inserted into the locking block 251 (the outer side of the switch valve pipeline is jointed with the sealing ring 2566), the locking block 251 is pushed by a single hand, the switch valve pipeline extrudes the elastic pad of the hollow plate 2561 to drive the hollow plate 2561 to slide along the inner wall of the sliding groove 257 (the micro spring 2562 generates elastic deformation), the reciprocating rod 2563 drives the pressure plate 2564 to slide along the inner wall of the jointing groove 259, and the pressure plate 2564 extrudes the wrapping bag 2565. Because the whole parcel bag 2565 is inlaid in the sealing groove 258, and one side of the parcel bag 2565, which is far away from the pressure plate 2564, is tightly attached to the inner wall of the sealing groove 258, the inner wall of the parcel bag 2565 is tightly attached to the sealing ring 2566, the outer side of the sealing ring 2566 is matched with the inner wall of the sealing groove 258, the width of the parcel bag 2565 is larger than that of the sealing ring 2566, when the pressure plate 2564 extrudes the parcel bag 2565, the whole parcel bag 2565 is elastically deformed, the outer side of the sealing ring 2566 is uniformly stressed, the sealing ring 2566 is pushed to be tightly attached to the outer side of the switch valve pipeline, and the other hand rotates the rotary sleeve 26, the rotary sleeve 26 rotates around the thread groove 250, and the rotary sleeve 26 extrudes the convex block 2567 on the outer side of the pressure plate 2564, make the pressure plate 2564 continuously extrude parcel bag 2565 (the sealing ring 2566 closely laminates in the ooff valve pipeline outside), and it is spacing to pressure plate 2564, the manual latch segment 251 of promoting of one hand and the other hand rotate rotatory sleeve 26 the two and complement each other, when promoting the latch segment 251 at every turn, it dies to rotate rotatory sleeve 26 fast, prevent that latch segment 251 from reseing, it is repeated many times, until latch segment 251 completely pushes away motionless, the pressure plate 2564 is the biggest to the extrusion force degree of parcel bag 2565 this moment, the sealing ring 2566 closely laminates in the ooff valve pipeline outside, the leakproofness is strong, compare the wearing and tearing that the fast joint has avoided the ooff valve pipeline, cause ooff valve pipeline edge unevenness, the problem that sealed not tight and produce the gas leakage when leading to the sample.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present 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 solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present invention.
