The base comprises a sleeve portion connected with the bottom pipe and a first pivoting plate comprising a guide groove. The rotary seat comprises a clamp for clamping the supporting pipe and a second pivoting plate comprising a through hole. The first pivoting plate and the second pivoting plate are pivoted together at a pivoting point, when the first pivoting plate and the second pivoting plate rotate relatively, the through hole is kept align to the guide groove. The locking piece penetrates through the through hole and the guide groove and clamps and fixes the first pivoting plate and the second pivoting plate. Through that a certain distance exists between the locking piece and the pivoting point, the load carrying capacity is increased.
