Abstract: A fence structure has a plane extended from the top of a connecting board to a vertical pipe and an embedded opening formed at corresponding position for embedding the vertical pipe. A protective flange is protruded from each of two corresponding sides of the embedded opening, attached onto a horizontal pipe for passing the vertical pipe to an inner wall of a hole, and installed at a position in the same displacing direction when the angle of the vertical pipe is adjusted. The horizontal pipe is formed by a main body with an opening on the longitudinal side and a cover disposed at the opening position and coupled to the main body. While adjusting the angle of the fence, the vertical and horizontal pipes are prevented from hitting each other or scratching their outer surfaces. In addition, the time and labor of assembling the fence can be reduced.
