[0013] By using the above technical solution, rotating the connecting turntable causes the threaded rod to rotate, which in turn causes the moving block to compress the return spring. The increased thrust of the return spring pushes the adjusting positioning plate to forcefully press against the fixed connector. By adjusting the compression of the return spring, the thrust on the fixed connector can be adjusted.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes the interlocking of an elastic fixing buckle and a limiting groove on a fixed connector head. When the filter cartridge needs to be disassembled, simply rotating the connecting frame completes the disassembly, facilitating the assembly and disassembly of the filter cartridge and increasing efficiency. Simultaneously, rotating the connecting turntable causes the threaded rod to rotate, which in turn compresses the return spring of the moving block. The increased thrust of the return spring pushes the adjusting positioning plate against the fixed connector head, ensuring a tight fit between the sealing gasket in the upper limit groove of the fixed connector head and the elastic fixing buckle, thus preventing poor sealing.
