Therefore, the reset spring and the scraper are arranged, the impurities adsorbed by the third magnetic piece are scraped off through the movement of the scraper, the influence of the impurities on the use of the closing plate is reduced, and the overall use is more stable.

[0019] Further, the scraper is provided with a blocking plate located at one end of the scraper close to the bottom of the fixed groove. The blocking plate abuts against the groove wall on the side of the fixed groove away from the positioning rod.
