1. A composite frame comprising:
a frame body including
two support units spaced apart from each other in a left-right direction, each including
an upright rod extending in a vertical direction transverse to the left-right direction,two leg rods spaced apart from each other in a front-rear direction transverse to the left-right direction and the vertical direction, each of said leg rods being pivotably connected to said upright rod, being pivotable relative to an imaginary plane defined by said upright rods of said support units, and having a coupling section that extends in the left-right direction,two fastening members respectively coupled to said upright rod and one of said leg rods, anda limiting member pivotably connected to the other one of said leg rods and operable to be pivoted relative to said other one of said leg rods to cross said upright rod and said one of said leg rods so as to be stopped by said fastening members,wherein each of said fastening members is operable to urge said limiting member to abut against the respective one of said upright rod and said one of said leg rods,two lower connecting rods spaced apart from each other in the front-rear direction, extending in the left-right direction, and each having two ends that are sleevingly and respectively connectable with said coupling sections of a corresponding opposite pair of said leg rods of said support units, said leg rods in said opposite pair being opposite to each other in the left-right direction,two suspending units spaced apart from each other in the left-right direction, and each having a first end that is sleevingly connectable with a top portion of said upright rod of a corresponding one of said support units and a second end that is distal from said first end, andan upper connecting rod having two ends, each of which is sleevingly connectable with said second end of a corresponding one of said suspending units.
