[0025] Two universal wheels 15 are fixedly connected to the bottom of the base plate 1 near the right side, and a fixed block 16 is fixedly connected to the top of the universal wheel 15 near the left side. A limiting hole 17 is provided on the top of the fixed block 16, and a limiting block 18 is movably inserted into the inner cavity of the limiting hole 17. A threaded rod 19 is fixedly connected to the top of the limiting block 18. Two screw holes 21 are provided at the top of the base plate 1 near the right side. The top of the threaded rod 19 passes through the adjacent screw holes 21 and is fixedly connected to a rocker 20. The threaded rod 19 and the screw hole 21 are threadedly connected, and the limiting block 18 and the limiting hole 17 match each other.

[0026] Working principle: The utility model is a municipal road marking device. During use, the handle 14 can be pushed to make the roller 2 and the universal wheel 15 drive the device to move. The setting of the universal wheel 15 can facilitate the steering of the device when it is transferred. When it is necessary to mark a straight line, the universal wheel 15 is first adjusted so that the limiting hole 17 on the top of the fixing block 16 is located directly below the limiting block 18, and then the rocking wheel 20 is rotated. The rocking wheel 20 drives the threaded rod 19 to rotate in the inner cavity of the screw hole 21. The threaded rod 19 moves downward relative to the screw hole 21 under the action of the thread, and the threaded rod 19 drives the limiting block 18 to move downward to the inner cavity of the limiting hole 17, thereby locking the direction of the universal wheel 15 to prevent it from rotating. When the device needs to draw a straight line, the front wheel for adjusting the direction can be locked, so that the device can only travel in a straight line, thereby improving the efficiency of novice road marking.

[0027] When marking a line, the battery 8 is used to power the pump 9, which extracts the material from the storage barrel 5 and sprays it out from the discharge nozzle 12, and then pushes the device to move to achieve the marking operation;

[0028] When the marking is completed, the rocker 20 is shaken again, and the rocker 20 drives the threaded rod 19 to rotate. The threaded rod 19 moves upward relative to the screw hole 21 under the action of the thread, and the threaded rod 19 drives the limit block 18 to move to the inner cavity away from the limit hole 17, thereby releasing the fixation of the universal wheel 15, which makes it convenient to turn the device when moving.
