[0032] Specifically, the two ends of the second spring 908 are respectively fixedly connected to the limiting ring 903 and the ring piece 906, and the limiting strip 907 is adapted to the groove 904. The advantage is that the limiting strip 907 and the groove 904 are set, and the limiting strip 907 is used to limit the insertion rod 905.

[0035] Embodiment 2: Figure 2-6 As shown, as an improvement to the previous embodiment.

[0036] Specifically, the slide bar 801 is slidably connected to the base tube 7, and the two ends of the spring 1 802 are respectively fixedly connected to the top ring 803 and the base tube 7. The advantage is that when the tube seat 10 and the vacuum pipeline 4 are installed, the insert tube 12 and the seal 804 are in close contact, and the tube seat 10 and the vacuum pipeline 4 compress and deform the sealing ring 11, thereby improving the sealing effect during the connection. At this time, the spring 1 802 is in a compressed state. When the tube seat 10 and the vacuum pipeline 4 need to be separated, the hand holds the grip 902 and the pressing plate 910, and the pressing plate 910 is squeezed to rotate the pressing plate 910 relative to the grip 902. The long groove 911 drives the fixing plate 909 and the insert rod 905 to move along the sleeve 901 until the insert rod 905 is separated from the insert tube 12.

When the tube seat 10 and the vacuum pipeline 4 are installed, the cannula 12 and the seal 804 are connected. When the tube seat 10 and the vacuum pipeline 4 are in tight contact, the sealing ring 11 is compressed and deformed, thereby improving the sealing effect during connection. At this time, the spring 802 is in a compressed state. When the tube seat 10 needs to be separated from the vacuum pipeline 4, the grip 902 and the pressing plate 910 are held by hand, and the pressing plate 910 is pinched to rotate the pressing plate 910 relative to the grip 902. The long groove 911 drives the fixing plate 909 and the insertion rod 905 to move along the sleeve 901 until the insertion rod 905 is separated from the insertion tube 12. At this time, the spring 802 rebounds and pushes the insertion tube 12 upward, thereby improving the disassembly speed. The structure is ingenious and very practical. The connecting seat 17 cooperates with the mounting tube 15, and the modular joint design has a fast assembly speed.
