The first cylinder is telescopic to drive the first connecting rod and the first support plate to rise against the formwork, the first rotating rod rotates the first connecting block to an upright state, the second rotating rod adjusts the second support plate to be level with the first support plate, and the second cylinder is telescopic to drive the second support plate to rise against the formwork. When it is necessary to support the formwork on both sides, the first rotating rod tilts the second support rod to drive the rotating mechanism to tilt, and then adjusts the second rotating rod to make the second support plate level with the inclined formwork, and then the second cylinder telescopic drives the second support plate to resist the formwork, which effectively realizes that the existing civil engineering formwork support structure is integrated, and the support angle can be adjusted according to the inclination of the formwork, so that the diversity of the support structure is enhanced, and the height of the support structure can be adjusted at the same time.
