The other end of the steel wire rope 3 is fixedly connected with the crossbar 4, and the bottom of the both ends of the kick box 1 is welded with the connecting piece 5. The surface of the connecting piece 5 is provided with the fixed hole 6. The kick box 1 is fixed to the ground surface by means of the nut through the fixed hole 6 of the connecting piece 5 by the foundation bolt. The top of the both ends of the kick box 1 is rotationally connected with the vertical rod 7. The two vertical rods 7 ends are provided with fixed structures and the both ends of the crossbar 4 respectively. In the embodiment, one person can quickly install, significantly improve the construction efficiency, and be particularly suitable for emergency or frequent adjustment construction scene. The product is easy to fold and unfold, small in size, convenient to carry and store, and effective in managing construction space.
