[0002] Municipal road traffic markings include road surface markings, arrows, text, signs, and road edge delineators, among other traffic safety facilities. Generally, road marking devices are used to create these markings. These devices are road construction machines used to draw guide and warning lines on the ground in places such as roads, highways, and parking lots. Road marking devices are fast, efficient, and accurate, and are widely used in urban planning and highway construction, minimizing the construction period and reducing economic investment.

[0003] A line marking device generally includes a vehicle body, wheels, a storage tank, and a nozzle. The wheels are rotatably connected to the vehicle body, and include front and rear wheels. The front wheels can steer, thus controlling the vehicle's direction of travel. Some vehicles have handles fixedly connected to the body for manual pushing; others have a motor fixedly connected to the body, which drives the wheels to rotate, causing the vehicle to move. The storage tank is fixedly connected to the vehicle body and contains molten paint. The nozzle is connected to the storage tank and fixedly connected to the vehicle body, with the nozzle facing the ground. Guide lines are pre-drawn on the ground, and then the nozzle is aligned with the guide lines, spraying paint along the guide lines to form traffic markings.

[0004] However, when drawing non-linear traffic markings such as arrows, diamonds, and text, the marking devices in related technologies often require adhering a template to the ground, then spraying paint onto the template with a nozzle, and finally removing the template after the paint has cooled and set, thus forming the non-linear traffic markings. The process of fixing and removing the template can easily lead to inefficiencies. Summary of the Invention
