The invention provides a solar wing unfolding mechanism for a microsatellite and an installing method. The solar wing unfolding mechanism comprises a female base, a male base, a rotary shaft, a T-shaped cold welding prevention pad, a '-'-shaped gasket, a left rotating torsional spring, a right rotating torsional spring, a compression spring, a locking shaft and locking nuts. The rotary shaft penetrates through five coaxial lug holes formed through mutual cooperation of the female base and the male base. The left rotating torsional spring and the right rotating torsional spring penetrates through the rotary shaft to be symmetrically installed, and extending arms of the torsional springs respectively enter arm grooves of the female base and the male base; the locking shaft and the compression spring are both installed in holes of the male base, the head portion of the locking shaft executes the movement along the cylindrical face of the female base in a round track way in the solar wingunfolding process, and th
