[0002] Road and bridge engineering refers to the survey, design, construction, maintenance, and management of roads and bridges. During road and bridge engineering, workers are required to use marking devices to mark the road surface.

[0003] At present, a Chinese utility model with the announcement number CN213979993U discloses a marking device for construction. The marking device for construction includes: a base plate; a handle, the handle is fixedly mounted on the base plate; a stirring mechanism, the stirring mechanism is arranged on the base plate, the stirring mechanism includes a stirring tank, the stirring tank is arranged on the base plate and fixedly connected to the base plate, a first motor is fixedly mounted on the top of the stirring tank, a connecting rod is arranged in the stirring tank, the top end of the connecting rod extends to the top of the stirring tank and is fixedly connected to the output shaft of the first motor. The marking device for construction provided by the utility model realizes the function of quickly stirring and crushing the lime added to the stirring tank by setting a stirring mechanism, avoids uneven manual stirring, blocks the feed pipe, and improves work efficiency to a certain extent. The marking mechanism is set so that workers can quickly mark the ground at the construction site and reduce the labor intensity of workers.

[0004] To sum up, although the marking device can achieve the purpose of stirring and mixing, there are still certain problems when using it.

When marking, the staff needs to clean the ground in advance to prevent dust and fallen leaves from hindering the marking work, resulting in delays in the marking work and heavy fatigue of the staff. At the same time, when the staff needs to push the marking device to mark a straight line, it is easy for the marking device to move deviations due to the staff's force control, resulting in deviations in marking, causing the drawn lines to not conform to the original design and poor practicality.
