[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model uses a starting motor and a warning light to make the rotating disk move through the connecting rod, which in turn moves the connecting rod, which in turn moves the slider. Through the limiting rod and the fixing block, the slider drives the gear through the teeth to rotate, which in turn drives the fixing rod and the warning light to swing left and right.

[0022] Working principle: When using this utility model, the user starts the motor 14, which drives the rotating disk 11 to rotate. The rotating disk 11 drives the connecting rod 9 through the connecting rod 12 and the connecting rod 13, which in turn drives the slider 5 to move. Through the limiting rod 7 and the fixing block 8, the slider 5 slides back and forth, which drives the gear 4 through the teeth 6 to rotate. The gear 4 then drives the warning light 17 to swing back and forth through the fixing rod 15, thus activating the warning light 17. This allows the warning light 17 to warn driving vehicles, ensuring that driving vehicles can see the highway maintenance warning sign and guaranteeing the safety of highway maintenance workers at night.

[0023] In summary, this highway maintenance warning device, by starting the motor 14 and the warning light 17, causes the rotating disk 11 to move via the connecting rod 13, which in turn drives the connecting rod 9 to move. The connecting rod 9 then drives the slider 5 to move. Through the limiting rod 7 and the fixing block 8, the slider 5 drives the gear 4 to rotate via the teeth 6. The gear 4 then drives the fixing rod 15 and the warning light 17 to swing left and right. This achieves the goal of warning vehicles through the warning structure, preventing vehicles from having difficulty seeing the highway maintenance warning sign, and ensuring the safety of highway maintenance workers at night.
