At this time, the lead screw nut 26 moves forward on the outer surface of the lead screw 25. The lead screw nut 26 synchronously drives the movable plate 27 to move forward. The movable plate 27 moves forward to expose the square groove 21. At this time, under the action of gravity, the building materials and tools directly fall to the ground through the square groove 21, without the need for workers to carry the building materials and tools down. Then, the motor 24 drives the lead screw 25 to rotate counterclockwise, and the lead screw nut 26 drives the movable plate 27 to move backward to close the square groove 21;

[0040] This step is convenient for re - transportation, greatly reduces the time of manual handling, thereby improving the overall operation efficiency and also reducing the labor intensity of manual handling.
