[0036] When in use, the handle 30 is toggled to draw the rod 28 into the inner cavity 4, and the rod 28 is kept in this state, and then the filter element 8 is installed into the filter body. As the filter element 8 continues to go deeper into the filter body, the second inner ring 7 of the filter element 8 will abut against the support block 9. At this time, the limiting hole 13 of the first inner ring 12 and the rod 28 are located on the same horizontal line. At this time, the handle 30 is released, and under the rebound effect of the spring 29, the rod 28 is automatically inserted into the limiting hole 13 to achieve the limiting fixation of the first inner ring 12, thereby cooperating with the support block 9 to complete the limiting fixation of the filter element 8 and prevent the filter element 8 from falling off;
