A magnetic induction protecting structure comprises a platform, an induction ruler, an induction head and a protection assembly. The protection assembly covers an induction distance between the induction head and the induction ruler completely for scraping off the chips and dust on the induction ruler and to prevent the chips and dust from being fallen into or accumulated in the induction distance, so as to ensure the quality of the magnetic induction signals between the induction head and the induction ruler, and to prolong the life of the induction head and the induction ruler.
