Description

[0002] Before the construction of a building or a bridge or road, it is necessary to mark the rough outline of the drawing on the ground and set auxiliary lines, and the auxiliary lines are mostly drawn with white lime. The commonly used line marker is a base plate plus a marking box, and white lime powder is added inside the marking box. The base plate can evenly sprinkle the white lime powder inside the marking box on the ground through the position where the wheels move, leaving the required mark lines. However, when the box cover of the line marker in the prior art is opened due to the vibration of the device, the lime powder inside is easily blown out by the airflow in the air, which can easily cause eye discomfort to the user. In addition, when the marking box stops during the marking process, the lime powder inside the marking box continues to flow, causing waste. Therefore, it is necessary to improve the prior art.
