Structure of water-saving device

A structure of water-saving device, comprising a base, an adjusting ring and a gland;

• the base having an inlet channel;
• the adjusting ring being mounted in the inlet channel;
• the gland being movably positioned in the base to limit the adjusting ring in the base;
• and the adjusting ring being made of a soft deformable material,
• wherein a central part of a bottom surface of the base forms a socket to limit the gland;
• multiple inlet holes are arranged on the bottom surface of the base to surround the socket;
• multiple ribs are further protruded on the bottom surface of the base to surround the inlet holes and the location of each rib corresponds to a middle of two inlet holes;
• the base has a protruding plate which protrudes from an inner wall near the top of the base;
• the protruding plate has a curved guiding surface;
• the gland has its top forms a lid;
• a central part of a top surface of the lid sinks downward to form a recess;
• a central part of a lower surface of the lid sinks downward to form a sinking column;
• a central part of the sinking column is elongated downward to form a guiding protrusion to be received within the socket,
• as such, when being assembled, the adjusting ring is mounted around the sinking column of the gland and the adjusting ring is mounted in the base with the sinking column;
• when the lid of gland is subject to be forced, the lid slides through the protruding plate with the curved guiding surface and is engaged in a location lower than the protruding plate, which limits the lid, simultaneously, the adjusting ring positioned on the ribs is lust located between the lid of the gland and the ribs of the base.
