At this time, the handle 24 can be pulled upward to pull the filter frame 18 out of the water outlet pipe 17. When the filter frame 18 needs to be installed, it is only necessary to hold the handle 24 and press it downward. The outside of the curved plate 23 will first contact the bottom plate 14 and slide inward, and then the curved plate 23 will rotate. At this time, the sliding column 21 will slide toward the inside of the fixed shaft 20, and the spring 22 can be compressed. When the curved plate 23 slides out from the inside of the bottom plate 14, it will rebound with the help of the spring 22. At this time, the curved plate 23 will be reset and can be engaged with the bottom of the bottom plate 14.
