A pole assembly includes a supporting pole, a connecting pole, and a reinforcing pole. A first end of the reinforcing pole is pivotably connected to a first end of the supporting pole. A first end of the connecting pole is pivotably connected to a second end of the supporting pole. The connecting pole and the supporting pole each have a U-shaped cross-section. A locking slot is defined in a second end of the reinforcing pole. A locking portion is formed from a middle portion of the connecting pole. When to use the pole assembly, the locking portion extends through the locking slot and is bent to contact with reinforcing pole, to connect the second end of the reinforcing pole to the middle portion of the connecting pole. |
