[0028] The two left connecting tubes 4 are both provided with sliding grooves inside, and the outer side of the sliding tube 5 is fixedly connected with a sliding bar 11 which is slidably connected with the sliding grooves.

[0029] When the annular plate 12 is pulled to move to the left, the slide bar 11 on the sliding tube 5 will move in the slide groove in the left connecting tube 4 to ensure the moving direction of the slide bar 11 .

[0030] There are four slide bars 11 , and the right sides of the four slide bars are fixedly connected to the annular plate 12 , and the diameter of the annular plate 12 is greater than the diameter of the left connecting pipe 4 .

[0031] After the slide bar 11 drives the sliding tube 5 to move to the left, the annular plate 12 will hit the right end of the left connecting tube 4 and stop, thereby ensuring the moving distance of the sliding tube 5.

[0032] Among them, the single sliding tube 5 has clearance holes on both the front and rear sides thereof, and the right connecting tube 6 has two fixing devices 13 fixedly connected thereto, which are respectively engaged with the two clearance holes.

[0033] When the sliding tube 5 is slid to the right, the annular plate 12 hits the left end of the right connecting tube 6 and stops. At this time, the clearance hole on the sliding tube 5 is aligned with the fixing device 13, so that the sliding tube 5 is fixed.

[0038] Working principle:

[0039] When it is necessary to clean the dirt, close the first water valve 3 and the second water valve 7 on one side of the front or rear. At this time, one of the water pipes in the front and rear is in a waterless state. Then pull up the pull ring 133 and move the annular plate 12 to the left to leak out the inside of the right connecting pipe 6. Finally, the filter screen 10 can be replaced or cleaned through the bolt 15 to achieve the purpose of descaling. Repeat the above operation to close the first water valve 3 and the second water valve 7 on the other side, and the filter screen 10 on the other side can be replaced or cleaned.
