Prefabricated assembly type staircase handling frame

The utility model discloses a prefabricated assembly type staircase operation frame which comprises a first supporting leg and a supporting mechanism, combination mechanisms used for combination installation are arranged on the two sides of the upper portion of the first supporting leg, and the supporting mechanism used for assembly supporting is arranged in the middle of one side of the first supporting leg. Adjusting mechanisms used for height adjustment are installed on the two sides of the interior of the first supporting leg. Compared with an existing device, the prefabricated assembly type staircase operation frame has the advantages that the screwing bevel gear, the transmission lead screw and the adjusting lead screw are connected in a bevel tooth meshing mode, so that when the screwing bevel gear is rotated, the adjusting lead screw can rotate; accordingly, the lifting frames and the supporting legs on the two sides and the first supporting legs can conduct synchronous telescopic movement, the purpos
