Due to the stepped design at the turning of the labyrinth groove 302e, the pull rod 302h at the bottom of the card slot 302a can only move along a specific track and cannot move backward. When the pull rod 302h enters the groove above it along the labyrinth groove 302e, at this time, the pull rod 302h and the buckle 302f fix the first sign board 301e, and at this time, the first sign board 301e is in the inserted state. Press the first sign board 301e forcefully in the insertion direction again, the pull rod 302h continues to move along the lower part of the labyrinth groove 302e, and the buckle 302f is unlocked at the same time. The elastic member 302i uses the spring tension to eject the first sign board 301e. When the first sign board 301e is inserted into the first through hole 301c, the second sign board 301f is inserted into the second through hole 301d. When the "working here" state is required, take out the first sign board 301e and insert it on the other side. When the blank state is required, insert the second sign board 301f into the first through hole 301c, then insert the first sign board 301e into the second through hole 301d. The whole device avoids the problems of separately taking and arranging multiple sign boards. The second sign board 301f is provided with a blank state, which does not need to be removed when no marking work is required and can be permanently arranged, better compatible with equipment or cabinets, and information or precautions can also be sprayed on this state page.
