An adjustable drawer, comprising:

• at least two connecting assemblies, being slidably connected to each other in a first direction to form a drawer body;
• wherein each of the at least two connecting assemblies comprises at least two connecting members arranged in a second direction;
• two adjacent ones of the at least two connecting members in the second direction are slidably connected to each other;
• and the second direction is perpendicular to the first direction;
• at least one fastening member, configured to lock two adjacent ones of the at least two connecting members in the first direction or in the second direction with respect to each other, so as to restrict the two adjacent connecting assemblies in the first direction or in the second direction from being detached from each other;
• wherein, the two adjacent connecting members in the first direction are slidable with respect to each other to enable a size of the drawer body in the first direction to be increased or decreased;
• the two adjacent connecting members in the second direction are slidable with respect to each other to enable a size of the drawer body in the second direction to be increased or decreased.
