摘要:
A positioning device of a magnetic ruler is used to position the magnetic ruler onto a guideway, so as to prevent the magnetic ruler from being peeled off the guideway as a result of the reduction of the adhesiveness and to maintain the magnetic induction of the magnetic ruler. Moreover, the restriction assembly can also protect the magnetic ruler and keep it from dust.
