The conducting plate 16, the motor 4 and the battery 17 are electrically connected. The iron sheet 15 not only plays a role of triggering, but also plays a role of fixing.

When the magnetic iron sheet exchange plate works, the magnet 20 is placed at the lower end of the front surface of the exchange plate 3, the iron sheet 15 moves forwards under the influence of magnetic force until the iron sheet 15 is abutted against the two conducting sheets 16, and the whole circuit is closed. At this point the motor 4 rotates the coiled wire 9 and the wire 9 pulls the plunger 8 inward, compressing the spring 7 with the plunger 8. Thereby retracting the insert 8 into the transpose plate 3. The purpose of detaching the exchanging plate 3 is achieved.

As can be seen from the above, the disc 5 and the extension 51 serve to support the connecting block 6, so that the insert 8 is always aligned with the through slot 31. Then, the spring 7 is pressed by the elasticity of the spring 7 to generate a reaction force. When the motor 4 stops operating, the spring 7 can eject the insert 8 from the exchanging plate 3.

The height adjustment is achieved by inserting the threaded rod 23 into different threaded holes 24.

The working principle is as follows: when the device is used, a teacher writes Korean sentences with wrong grammar on a blackboard formed by the conversion board 3. Each transpose plate 3 fills out a word. Then the hand-held magnet is placed on the lower end of the front face of the exchanging plate 3 where the word is wrongly positioned. The iron sheet 15 moves forward under the influence of the magnetic force until the iron sheet 15 collides with the two conducting strips 16 and the whole electric circuit is closed. At this point the motor 4 rotates the winding wire 9 and the wire 9 pulls the insert 8 into the changeover plate 3.

Meanwhile, the motor 4 drives the gear 10 to rotate, the gear 10 drives the rack 11 to move, the transverse bar 13 is jacked up, the transverse bar 13 is contacted with the inner wall of the change plate 3, the bulge 131 of the transverse bar 13 extends into the groove 31, and therefore the insert block 8 of the adjacent change plate 3 is jacked out.

Since the magnet 20 firmly attracts the iron sheet, the magnet 20 is held by hand and pulled outward, the exchange plate 3 is taken out, and the above operation is repeated to take down another exchange plate 3 whose position needs to be exchanged. The removed exchanging plate is mounted at the correct position, two hands are placed at two sides of the exchanging plate 3 during mounting, the inserting block 8 is pressed into the exchanging plate 3 by fingers, and the removed exchanging plate 3 is pressed into the correct position.
