then, the singlechip control circuit controls the first motor to rotate clockwise through the driving circuit, drives the lead screw to rotate clockwise, and further drives the whole bolt disassembling assembly to move a preset distance x (the moving distance can also be dynamically measured through external positioning equipment) along the slide rail to the direction of the hardware fitting panel, so that the front end of the bolt fixing sleeve is contacted with the bolt 52 to be disassembled of the hardware fitting (a plurality of bolts 52 to be disassembled are arranged on one hardware fitting panel, and each bolt to be disassembled corresponds to a nut to be disassembled on the other side of the hardware fitting panel); at the moment, the singlechip control circuit controls the second motor to rotate anticlockwise through the driving circuit, so that all the bolt fixing sleeves are driven to rotate clockwise through the driving belt of the gear set, and meanwhile, the singlechip control circuit controls the first motor to continuously rotate clockwise through the driving circuit so as to drive the whole bolt disassembling assembly to move towards the hardware fitting panel along the slide rail, so that all the bolts 52 to be disassembled are clamped in the bolt grooves of all the bolt fixing sleeves;
