[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By providing a mounting frame, when cleaning the sealing gasket, the sealing gasket is placed on the upper surface of the cleaning table. At this time, the position of the sliding block inside the mounting frame makes the water spray head located directly above the sealing gasket. At this time, the pull of the spring is applied to the limit plate, so that the end of the abutment rod abuts against the side of the anti-slip groove, thereby greatly improving the friction between the abutment rod and the side of the mounting frame, thereby fixing the position of the water spray head.

[0015] 2. By setting up a cleaning table, when the water spray head cleans the sealing gasket, the water drips onto the sieve plate through the sieve holes on the surface of the cleaning table after flushing the sealing gasket, so that the sieve plate filters the clean water, and the impurities in the water will be retained on the surface of the sieve plate, and the filtered water will be stored in the bottom of the water tank, thereby realizing the recycling of clean water and saving a lot of water resources. The device has a simple structure, ingenious design, simple operation, and is easy to promote and use in practice. BRIEF DESCRIPTION OF THE DRAWINGS
