[0026] The connecting device includes a sliding rod 8, a sliding groove 9 and a limiting groove 10. The number of sliding rods 8 and sliding grooves 9 corresponds to each other. The sliding grooves 9 are opened on the inner wall of the water pipe 3; the sliding grooves 9 are distributed circumferentially with the central axis of the water pipe 3; the limiting grooves 10 stacked up and down and arranged in parallel are opened on the inner wall of the water pipe 3; the limiting grooves 10 are connected to the sliding grooves 9, and the limiting grooves 10 and the sliding grooves 9 are F-shaped; the sliding rod 8 is connected to the outer wall of the mounting tube 4, and there are multiple sliding rods 8 distributed circumferentially, and the sliding rod 8 is slidably connected with the sliding grooves 9 and the limiting grooves 10.

[0027] In an optional embodiment, an observation chute 11 is opened on the inner wall of the water supply pipe 3, and the observation chute 11 is connected to the two limit grooves 10, and the observation chute 11 is parallel to the limit grooves 10; wherein, when the sliding rod 8 moves circumferentially along the limit groove 10, it will first contact the observation chute 11, and then the sliding rod 8 will slide to the limit groove 10 below through the observation chute 11. At this time, the two filter blocks 7 and the filter screen 6 are exposed to the outside world and can be viewed through the observation window 15. If maintenance is required, the installation cylinder 4 can be rotated to make it move circumferentially and then taken out. If no maintenance is required, it can be returned to its original path.

[0028] In an optional embodiment, the mounting cylinder 4 is composed of two arc plates 12, which are detachably connected to each other, and the inner wall of one arc plate 12 is used to connect the support ring 5; wherein the two arc plates 12 are slidingly connected to each other, and the arc plate 12 is connected to the complete support ring 5 to support the filter component.
