PURPOSE: A fence for adjusting the angle of a crossbar is provided to install the crossbar by freely twisting in all directions and to reduce production costs and a construction period by simplifying a joint member. CONSTITUTION: A fence for adjusting the angle of a crossbar comprises a circular post(1), a crossbar(3), and a bracket(2). The top of a circular post is curved by bending a circular pipe in half. The circular post is formed with a screw through groove(8). The bracket comprises a post through groove(5), a screw through groove, and a crossbar loading and unloading hole(6). The fixing screw(4) passes through the screw through grooves for fixing. The central part of the post through groove is shaped into a circle in order to insert the circular pipe. The width of the post through groove is widened into the shape of an ellipse toward the upper and lower parts thereof for freely twisting and installing a crossbar. |
