Foldable device

A foldable device comprising:

• a pivot base;
• three supporting rods extending through the pivot base, each of the supporting rods having a top section that is located above the pivot base;
• a linkage unit including a pivot member that is located above the pivot base, and a linkage rod that is pivotably connected to the pivot member, the linkage rod having a pivot section that is pivotably connected to the pivot member, and a moving section that is opposite to the pivot section;
• and
• at least one folding rod unit pivotably connected to one of the supporting rods, the moving section of the linkage rod being slidably mounted to the at least one folding rod unit, the at least one folding rod unit including a folding rod that has a connecting section which is pivotably connected to the top section of the one of the supporting rods, and a swing section which is opposite to the connecting section, the folding rod of the at least one folding rod unit being movable relative to the one of the supporting rods between a folded position, in which the swing section of the folding rod is adjacent to the pivot base, in which the pivot section of the linkage rod is adjacent to the folding rod, and in which the moving section of the linkage rod is adjacent to the swing section of the folding rod, and an expanded position, in which the swing section of the folding rod is distal from the pivot base and is located at one side of the top section of the one of the supporting rods opposite to the pivot base, and in which the moving section of the linkage rod is distal from the swing section of the folding rod.
