But the pressing-down buckle rib 31 can outwards push up the rotating claw 8, and the top end of the spring post 32 contacts the top end of the spring platform 26 on the waterway board 2.

The pivoting pawl 8, when pivoted about the hinge shaft 9, pulls the telescopic rod assembly to move. The moving direction of the telescopic rod assembly is far away from the driving inclined plane 15 at the bottom end of the core changing rod 1, so that the telescopic rod assembly cannot contact with the core changing rod 1.

As shown in fig. 19, the filter element 3 is continuously lowered, the fastening rib 31 passes over the rib 81 of the rotating claw 8 and then reaches the position below the rib 81, the rotating claw return spring 7 drives the telescopic rod assembly to move, and the rotating claw 8 is driven to return in the moving process of the telescopic rod assembly, so that the fastening rib 31 is fastened. At this time, the spring column 32 is thoroughly retracted into the filter element 3 under the extrusion of the spring table 26, the gland 35 is abutted on the spring table 26, the filter element 3 cannot move down continuously, and the filter element 3 is installed in place.

When the filter element is disassembled, as shown in fig. 20 and 21, the core replacing bar 1 is pressed downwards, and the driving piece 13 moves through the first guide groove 52 and the second guide groove 62 respectively in the downward moving process, so that the rotating claw 8 swings around the hinge shaft 9, the rotating claw 8 releases the buckling rib 31, the spring column 32 stretches out of the filter element 3 under the pushing of the spring column resetting piece 33, the spring column 32 reversely pushes the filter element 3 to move upwards, and a user can lift the filter element 3 from the bracket 4 by grabbing the handle 36. After the core rod 1 is stopped being pressed, the rotating claw reset spring 7 drives the telescopic rod assembly to move, and the rotating claw 8 is driven to reset in the moving process of the telescopic rod assembly.
