Specifically, the magnetic plate 3 includes a guide seat 31, and guide strips 311 are respectively arranged on two opposite side walls of the guide seat 31;

the transmission mechanism 4 comprises a first guide block 43 and a second guide block 44 symmetrically arranged about the guide holder 31, wherein: the top of the first guide block 43 is an inclined plane, and the lower part of the first guide block is arranged close to the guide seat 31 and is in sliding connection with the bottom of the guide strip 311; the bottom of the second guide block 44 is an inclined plane, is positioned close to the guide seat 31, and is slidably connected with the top of the guide bar 311.

And a connecting rod 8 is arranged between the first guide block 43 and the second guide block 44, so that when the second guide block 44 is driven by the toothed plate 42 to move, the first guide block 43 also moves synchronously.

Further, the bottom of the guide seat 31 in the embodiment is provided with a strong magnet, which is based on the position shown in fig. 4, when the guide block 2 moves up to the end of the waist groove. At this time, the two tooth plates 42 move to both sides at the same time. Along with the upward movement of the second guide block 44, the first guide block 43 moves upward to the upper position of the inclined surface, and at the same time, the first guide block moves upward to the lower position of the inclined surface. The guide seat 31 extends out of the frame 1 at this time, and magnetically connects the ferromagnetic body with the blackboard. Conversely, as the second guide block 44 is moved downward, it is moved downward to the lower position of the inclined surface, and at the same time, the first guide block 43 is moved downward to the upper position of the inclined surface. The guide holder 31 is retracted into the frame 1 at this time, and the ferromagnetic body is disengaged from the blackboard.
