The invention discloses a heat-static strong recovering type MEMS (Micro-Electro-Mechanical System) four-point support hanging beam structure which comprises a substrate, static pull-down electrodes, anchor areas, a hanging main beam and bending support beams, wherein the top face of the substrate is coated with the static pull-down electrodes, the hanging main beam is hung above the substrate through the four anchor areas and the bending support beams; during the process that the hanging main beam switches from a pull-down state ('down' state) to a hanging state ('up' state), the bending support beams are subjected to ohmic heating to stretch the hanging main beam, so that the effective rigidity of the hanging main beam is improved, and the restoring force is strengthened; longitudinal beams of the bending support beams adopt the design of double parallel wide and narrow beams, so that the hanging main beam is more stable, and after being heated, the hanging main beam can recover from the 'down' state to the 'up' state more easily. The invention further discloses a specific operating manner for enhancing the restoring force, and the method is simple, convenient and feasible.
