External wall panel hoisting device for fabricated building construction

The utility model relates to the field of fabricated building construction, in particular to an external wall panel hoisting device for fabricated building construction, which comprises a top plate and a bottom plate positioned below the top plate, a first screw rod is rotatably connected to the left side between the top plate and the bottom plate, and the outer walls of the first screw rod and a sliding rod are movably connected with movable plates; a supporting plate is fixedly connected between the two movable plates, by arranging sliding rods, lifting of the supporting plate is more stable, then a steering engine is started again to drive a folding plate to be put down, an air cylinder is started to drive a fixing plate to move backwards, and therefore the multiple external wall panels are clamped and fixed between a back plate and the fixing plate, the fixing effect is good, and the fixing effect on the external wall panels is improved; and a second motor is further started to drive a second lead screw t
