[0042] A quasi-triangular space is formed between the upper first bending section 11, the head end of the upper middle straight section 12, the middle first bending section 31 and the lower support member 2 (the head end of the upper middle straight section 12 can be regarded as a vertex of the triangular space); a quasi-triangular space is formed between the middle first bending section 31, the middle-middle straight section 32, the middle tail bending section 33 and the upper middle straight section 12 (the middle-middle straight section 32 can be regarded as a vertex of the triangular space); a quasi-triangular space is formed between the middle tail bending section 33, the tail end of the upper middle straight section 12, the upper tail bending section 13 and the lower support member 2 (the tail end of the upper middle straight section 12 can be regarded as a vertex of the triangular space); the above quasi-triangular space has higher bearing capacity and stability, which is conducive to improving the wind resistance of the butterfly-type wind-resistant support;
