A pole assembly includes four supporting poles spaced from one another, two rails each supported on two adjacent supporting poles, and a mounting apparatus. A number of fasteners are fixed on each of the supporting poles. Each fastener includes a head, a neck portion, and a fixing portion fixed to the supporting pole. The rails are in a row and positioned at a same height of the supporting poles. Each rail defines two locking slots adjacent to opposite ends of the rail. Each locking slot includes an opening and a locking hole communicating with the opening. Each rail is set on two adjacent supporting poles. The neck portions engage in the corresponding locking holes. The adjacent ends of two adjacent rails are fixed to the mounting apparatus. |
