1. An adjustable frame, comprising:
a central shaft part;
a rotatable frame part, rotatably connected to the central shaft part;
a movable frame part, provided on a side of the rotatable frame part away from the central shaft part; and
an adjustment mechanism, wherein an end of the adjustment mechanism is connected to the central shaft part, and an opposite end of the adjustment mechanism is connected to the movable frame part, wherein
the adjustment mechanism is configured to adjust a spacing between the movable frame part and the rotatable frame part with rotation of the rotatable frame part and the movable frame part,
wherein the adjustment mechanism comprises:
a fixed shaft, having a cylindrical shape and fixed to the central shaft part, wherein the fixed shaft is arranged coaxially with a rotating shaft of the rotatable frame part; and
a bendable connector, having a first end and a second end opposite to each other, wherein the first end is fixed to the central shaft part, the second end is connected to the movable frame part, and the bendable connector is configured to wind around a cylindrical surface of the fixed shaft with the rotation of the rotatable frame part and the movable frame part when the adjustable frame is folded outward, thereby driving the movable frame part to move toward the rotatable frame part.
