Mobile bar is driven mobile bar to move by after the active force of blank by the elastic webbing being arranged in support locating dowel, so that
Obtain the pulley being connected with mobile bar and enter line slip in sliding rail, utilize the relative fortune with mobile bar in blank rotation process
It is dynamic to complete whole erase process.
2nd, the utility model middle pulley is along along ring-like sliding rail sliding process so that erasing mechanism can not only dialogue
Plate body carries out positive erasing, when on the another side of pulley rotation to sliding rail, and erasing mechanism can also be realized to blank
Body carries out reverse side erasing；It is simple and practical, it is with low cost, it is easy to operate, it is widely used.
3rd, the utility model can be according to the difference of white board marker ink type, by the phase for adjusting mobile bar and connector
To position, wiped to realize wiping the different ink of difficulty, erasing effect is good.
4th, the utility model can make a certain portion in sponge block according to actual conditions in erasing by rotating cutting ferrule
Divide or the work of a few parts, and then realization is wiped unwanted part on blank body, the writing of remaining part is protected
Stay on blank body.
