The side of the spring 82 close to the mating plate 12 is fixedly connected to a fixing ring 83.

[0031] The above solution is adopted: by setting a positioning component 8, after the matching plate 12 drives the card block 13 to be inserted into the card slot, the pressure of the spring 82 on the lifting block 81 can be used to position the position of the anastomosis plate 3, so that the anastomosis plate 3 will not drive the card block 13 to detach.

[0038] The working principle of this utility model:

[0039] When in use, when the nanofiltration membrane 2 needs to be installed in the installation shell 1, the pushing block 19 is pushed to move in the limiting frame 20. The movement of the pushing block 19 will drive the connecting rod 7 to move, and the movement of the connecting rod 7 will drive the rotating ring 17 to rotate. The rotation of the rotating ring 17 will drive the extrusion plate 18 to squeeze the four lifting blocks 81 to move the extrusion spring 82. When the lifting block 81 moves and drives the matching plate 12 to rise, the matching plate 12 will drive the clamping block 13 to move to the appropriate position, and then the nanofiltration membrane 2 can be picked up and inserted into the installation shell 1. At this time, the matching plate 3 will be inserted into the matching groove 4, and the matching plate 3 will drive the sealing ring 10 to be inserted into the sealing groove 9. After the clamping block 13 is aligned with the clamping hole 14, the pushing block 19 is released, and the spring 82 undergoes elastic deformation to drive the lifting block 81 back to its original position. The movement of the lifting block 81 will drive the matching plate 12 to fit with the matching groove 11. At this time, the matching plate 12 can drive the clamping block 13 to be inserted into the clamping hole 14, and the position of the nanofiltration membrane 2 and the matching plate 3 can be fixed.
