By using above-mentioned technical proposal, one piece of transparency glass plate is fixed close to the side of paintbrush in drawing board so that paintbrush
It is drawn on clear glass, and because clear glass can see the graduation mark on drawing board, while can reuse, and is drawn in picture
Curve on plate can be wiped out conveniently.
The utility model is further arranged to：The detection bar is fixed with balancing weight close to scroll wheel one end.
By using above-mentioned technical proposal, balancing weight is set so that detection bar is saved by the weight laminating road surface of itself
It is artificial to the downward force of detection bar.
The utility model is further arranged to：The detection bar upper end is provided with handle.
By using above-mentioned technical proposal, handle is set in detection bar upper end, facilitates operating personnel to promote detection bar forward
Sliding.
In summary, the utility model has the advantages that：
First, when needing to detect the flatness of certain road section surface, base being placed on measurement road surface, then led to paintbrush
The upper end that fixation kit is fixed on detection bar is crossed, and causes paintbrush to be connected to drawing board surface, detection bar is then passed through into scroll wheel
Elapsed forward in groove, detection bar can follow the height on road surface to move up and down so that paintbrush depicted on drawing board one with
The consistent curve of road surface bumps situation, so as to measure conveniently and intuitively required data；
Second, setting balancing weight so that detection bar is fitted road surface by the weight of itself, eliminate it is artificial to detection bar to
Lower force.
