[0002] After the highway is completed and opened to traffic, due to the wear and impact of the wheels, the erosion and weathering of natural forces such as heavy rain, floods, sandstorms, ice and snow, sun exposure, and ice melting, as well as man-made damage and some defects left over from construction, the quality of the road will be affected. Therefore, after the road is completed and opened to traffic, maintenance and repair measures must be taken and continuously updated and improved. Road maintenance refers to the maintenance of roads in order to keep the road in good condition, prevent its quality from deteriorating, and provide good services to road users. The work carried out is a term in road technology and road engineering, which has a great effect on environmental protection. With the continuous development of society, more and more attention is paid to road maintenance, and the devices used in road maintenance have also begun to appear. However, when some paint spraying devices for road maintenance are in use, it is not convenient to retract and retract the spraying pipes, which affects the normal use of the device. In addition, when the device is used and placed, it cannot well avoid the phenomenon of clogging of the spray hole , and at the same time, it is impossible to avoid the volatilization of harmful gases at the nozzle when the device is placed. Finally, it is impossible to prevent the paint from adhering to the inner wall of the container for holding, so that the paint cannot be used to the greatest extent, and the spraying efficiency is reduced. At the same time, it is not possible to remind the staff to replenish in time when the paint is used up.
