Several connector assemblies 7 are also arranged above the testing platform 11. Each connector assembly 7 is connected to a driving component 8 that drives it to communicate with the inlet and outlet of the filter cartridge 10 located below.

[0027] Specifically, in this embodiment, the positioning seat 4 includes an upper seat 41 and a lower seat 42 connected vertically. The upper seat 41 has an upper positioning hole 31, and the lower seat 42 has a lower positioning hole 32. The lower positioning hole 32 and the upper positioning hole 31 are coaxially connected to form a positioning hole. Further, the upper end face of the upper positioning hole 31 is set at an angle to the central axis of the upper positioning hole 31 so that the filter element 10 can enter the upper positioning hole 31.

[0028] As shown in Figures 2 and 3, the elastic pressing assembly 5 includes an annular pressing block 51 that is radially slidably disposed within the lower seat 42 along the positioning hole. The annular pressing block 51 is located between the upper positioning hole 31 and the lower positioning hole 32, and can be fully exposed in the lower positioning hole 32. An elastic element 52 is disposed between the annular pressing block 51 and the positioning seat 4. A first guide rod 53 is disposed on the side of the annular pressing block 51 opposite to the elastic element 52. The first guide rod 53 is slidably connected to the lower seat 42, and a handle 55 is connected to the end of the first guide rod 53 located on the outside of the lower seat 42.

[0029] Furthermore, the annular pressure block 51 is connected to a second guide rod 54 coaxial with the first guide rod 53, and the second guide rod 54 is slidably disposed in a guide hole opened inside the lower seat 42; the elastic element 52 is preferably a spring sleeved on the second guide rod 54.
