2. A method of operating a safety control device for a machine tool, as applied to the safety control device for a machine tool of claim 1, characterized by: the method comprises the following steps:

(1) When the control box (1) needs to move, the supporting seat (402) is driven to ascend by the electric push rod (401), the second toothed plate (203) meshed with the transmission gear (405) moves downwards by the meshing force, the moving wheel (204) descends and lifts the equipment to be suspended, and at the moment, the control box (1) can be moved to a proper position by the moving wheel (204);

(2) The servo motor (501) is started to drive the threaded rod (503) to rotate, under the threaded connection force, the two movable blocks (505) are enabled to relatively displace, the protection structure (507) is driven to follow the relative displacement until the two protection covers (5071) relatively move and are attached, the two protection covers (5071) shield the display screen of the control box (1), and accidental damage to the display screen caused by external impact is effectively avoided;

(3) When the protective structure (507) moves, the sliding block (5073) at the inner side of the protective structure follows the displacement, so that the displacement stability of the protective cover (5071) is improved, meanwhile, the dust removing roller (5072) can move along the plane of the display screen, and the plane of the display screen is cleaned through the rolling and bonding of the dust removing roller (5072);

(4) When equipment needs to be used, the reverse start servo motor (501) drives the threaded rod (503) to overturn, the two protective structures (507) move back to expose the display screen, meanwhile, the worm (502) is meshed with the worm wheel (603), the rotating rod (602) is driven to turn round, the moving block (604) is further driven to move downwards until the first contact (605) is contacted with the second contact on the cooling fan (7), the cooling fan (7) is electrified to conduct cooling operation on the inner cavity of the control box (1) in an operating state, and flow of internal airflow is accelerated to achieve effective heat dissipation.
