s2, enabling the device to descend, switching on an electromagnet (48) power supply, sucking the electromagnet (48) with a magnetic block (49), enabling the clamping column (34) to be separated from the clamping groove, simultaneously driving the rotating plate (5) to rotate through the first motor (8), enabling the two third clamping plates (42) to be positioned on two sides of a brick respectively, switching off the electromagnet (48) power supply, enabling the clamping column (34) to be clamped in the clamping groove through the action of a second compression spring (33) to fix the first rotating shaft (9), enabling the two rotating plates (24) to rotate through the second electric cylinder (25), enabling the two third clamping plates (42) to clamp the left side and the right side of the brick, and lifting the brick;

s3, pushing the two baffles (22) to move downwards through the two first electric cylinders (20), enabling the two supporting plates (23) to move to the lower side of the brick, driving the first bevel gears (13) to rotate through the second motor (12), enabling the first bevel gears (13) to drive the two second bevel gears (16) and the two screws (15) to rotate, enabling the two supporting plates (17) to move towards the middle, enabling the two supporting plates (23) to move to the lower side of the brick, enabling the two supporting plates (23) to move upwards through the two first electric cylinders (20), enabling the top ends of the two supporting plates (23) to be in contact with the bottom ends of the brick, and continuously operating the second motor (12) to enable the two second clamping plates (38) to clamp the front side and the rear side of the brick;

s4, moving the brick to the upper part of a proper position through a lifting device, enabling two second clamping plates (38) to move to two sides through a second motor (12), simultaneously pushing a baffle plate (22) to move downwards through a first electric cylinder (20), enabling two supporting plates (23) to move to two sides of the brick, then contracting the first electric cylinder (20), enabling the two baffle plates (22) to move upwards through the action of a first compression spring (19), moving to the upper side of the brick, then placing the brick at the proper position, pushing two rotating plates (24) to rotate outwards through a second electric cylinder (25), separating a third clamping plate (42) from the brick, and then carrying other bricks.
