[0031] After the straight thread sleeve 1 is connected to the lower steel bar, the bracket 7 is plugged into the square seat 2, and then the pipe sleeve 9 is sleeved on the guide column 8 to complete the plug-in connection between the structure formed by multiple internal threaded pipes 11 and the bracket 7. When the upper steel bar is threadedly connected to the straight thread sleeve 1, the positioning sleeve 15 is sleeved on the upper end of the steel bar. At this time, the positioning sleeve 15 and the straight thread sleeve 1 jointly realize the support and limitation of the two ends of the steel bar.
