[0021] Working principle: During operation, rotate the adjustment block 9 to drive the adjustment screw rod 6 to rotate inside the threaded sleeve 5. The adjustment screw rod 6 rotates and moves upward. Under the action of the positioning bearing 8, the adjustment screw rod 6 drives the housing 7 to move upward. The housing 7 drives the positioning slide rod 22 to slide inside the positioning sleeve 21, which can ensure better stability when the housing 7 moves. At the same time, the housing 7 drives the first sign board 1 to move upward. The housing 7 and the strip-shaped frame 17 interact with each other to drive the bidirectional screw rod 16 to move upward. The bidirectional screw rod 16 drives the two second sign boards 2 to move upward simultaneously through the connection of the threaded movable sleeve 18. At the same time, the adjustment screw rod 6 drives the first bevel gear 10 to rotate. The first bevel gear 10 drives the second bevel gear 11 to rotate. The second bevel gear 11 drives the connecting rod 12 to rotate. The connecting rod 12 drives the third bevel gear 14 to rotate. The third bevel gear 14 drives the fourth bevel gear 15 to rotate. The fourth bevel gear 15 drives the bidirectional screw rod 16 to rotate. The bidirectional screw rod 16 drives the threaded movable sleeve 18 to move. The threaded movable sleeve 18 drives the positioning slider 19 to slide inside the positioning chute 20, which can ensure better stability when the threaded movable sleeve 18 moves. At the same time, the threaded movable sleeve 18 drives the second sign board 2 to move. The two second sign boards 2 move and unfold. Cooperating with the first sign board 1, it can increase the warning area of the sign to achieve a more eye-catching effect. After the two second sign boards 2 are fully unfolded, stop rotating the adjustment block 9. At this time, the first sign board 1 and the two second sign boards 2 move up to a certain height and also unfold for safety warning operations. After the labor hygiene activity ends, reverse-rotate the adjustment block 9, and the first sign board 1 and the two second sign boards 2 can be moved down and retracted. In this way, during the use of the safety warning sign for labor hygiene, it is convenient to adjust the unfolding or retracting, reducing the limitations, and thus facilitating better practicality.
