The aperture of the connecting hole 51 is matched with the shaft diameter of the rotating shaft 6; and a locking mechanism 3 is provided between each rotating shaft 6 and the fixed plate 5. Specifically, when in use, the positioning sleeve 2 is first fixedly sleeved on the steel column, and then the end of the steel pipe close to the steel column is inserted into the connecting sleeve 1, and the position of the steel pipe is fixed on the connecting sleeve 1. Since the connecting sleeve 1 and the fixed plate 5 are rotatably connected, the connecting sleeve 1 can be rotated in the horizontal direction. Therefore, when in use, the angle between the steel pipe and the steel column in the horizontal direction can be adjusted according to the actual construction situation for easy use. After the adjustment is in place, the locking mechanism 3 can be used to lock and fix the steel pipe on the steel column for easy assembly.

[0021] The specific setting method of the locking mechanism 3 is as follows: the locking mechanism 3 includes a locking block 31 and a polygonal locking groove 32 provided on the fixed disk 5, the polygonal locking groove 32 is respectively coaxially arranged with the connecting through hole 51, and the polygonal locking groove 32 is respectively provided on the top surface or the bottom surface of the fixed disk 5; the locking block 31 is respectively slidably sleeved on the end of the rotating shaft 6 away from the connecting sleeve 1, the horizontal cross-section of the locking block 31 is adapted to the shape of the polygonal locking groove 32, and the end of the locking block 31 close to the connecting sleeve 1 is respectively located in the polygonal locking groove 32, and the other end of the locking block 31 is threadedly connected with a locking bolt 33 horizontally penetrating the locking block 31. Specifically, in the initial state, the screw end of the locking bolt 33 is away from the rotating shaft 6. At this time, the rotating shaft 6 can be relative to the locking The block 31 can be rotated, that is, the connecting sleeve 1 can be rotated in the horizontal direction, so that when in use, the angle between the steel pipe and the steel column in the horizontal direction can be adjusted according to the actual construction situation; and after the adjustment is in place, the locking block 31 can be fixed on the rotating shaft 6 by rotating the locking bolt 33 until the screw end of the locking bolt 33 is tightly pressed against the rotating shaft 6, and because the horizontal cross-section of the locking block 31 is adapted to the shape of the polygonal locking groove 32, the end of the locking block 31 close to the connecting sleeve 1 is located in the polygonal locking groove 32, so that the connecting sleeve 1 cannot be rotated in the horizontal direction, so that the steel pipe can be locked and fixed on the steel column; in addition, since the locking block 31 is a sliding sleeve arranged on the rotating shaft 6, it is convenient to disassemble and assemble the locking block 31 on the fixed plate 5.
