Conveniently storable children height-increasing stool

A conveniently storable children height-increasing stool, comprising:

• two side plates (1) arranged opposite to each other;
• at least one support plate (2) connected between the two side plates (1) to provide a stepping surface (2a);
• a folding assembly (3) including two auxiliary support feet (3a) arranged opposite to each other;
• and
• a limiting device (4) formed by cooperation of the side plates (1) and the folding assembly (3);
• wherein the two auxiliary support feet (3a) are respectively rotatably connected to end faces of the two side plates (1), thereby enabling the folding assembly (3) to switch between an unfolded state and a folded state relative to the side plates (1);
• when the folding assembly (3) is in the unfolded state, the limiting device (4) locks the folding assembly (3) in an unfolded position, so that the auxiliary support feet (3a) and the side plates (1) cooperatively form a planar support structure;
• when the folding assembly (3) is in the folded state, the auxiliary support feet (3a) stack against outer or inner sides of the side plates (1) to reduce occupied volume;
• wherein the conveniently storable children height-increasing stool further comprises a fixing knob (6);
• the fixing knob (6) is provided with a threaded post (6a), each auxiliary support foot (3a) is provided with a transversely extending hinge hole (3a1), each side plate (1) is provided with a second mounting hole (1d) aligned with the hinge hole (3a1), and an end of at least one support plate (2) is further provided with a transversely extending second threaded hole (2c);
• the threaded post (6a) sequentially passes through the hinge hole (3a1) and the second mounting hole (1d) and then is screwed into the second threaded hole (2c) to rotatably secure the auxiliary support foot (3a) to the side plate (1).
