After the sand is scraped off, the rotating block is pressed upward by hand, and the piston moves upward at the same time and disengages from the depression at the upper end of the base. The sand in the upper shell flows out from the holes of the base with the water flow. After cleaning is completed, the piston descends and re-engages with the depression at the upper end of the base to prevent water from overflowing, thereby facilitating the cleaning of the sand inside the outer shell.

[0020] 2. The installation mechanism facilitates the installation and disassembly of the glass mirror.
