An anti-slip ring (10305) is fixedly installed on the outside of the correction electrode (10304), and the anti-slip ring (10305) is fixedly connected to the correction block (10303), which is convenient for providing buffering and anti-slip performance when the correction component (103) is placed for correction, so as to avoid scratches on the panel (10101), the electrode sheet (10105) and the correction electrode (10304); Step three, resetting is completed: the correction block (10303) is magnetically connected to the fixed magnetic block (10203), so that the correction block (10303) can be stored and fixed inside the fixed groove (10202), which is convenient for storing the correction component (103) during daily use to avoid the correction component (103) from being lost. A storage groove (10204) is opened between the two fixed grooves (10202), and the connecting strip (10301) is snap-connected with the storage groove (10204), so that the connecting strip (10301) can be stored and fixed.
