The working state of the magnetic type carrying structure device is as follows:

the working state is as follows:

firstly, carrying state: the fixing unit 10 is fixed in a fixing structure (such as a pocket of clothes) with the positioning column 11 exposed. The movable unit 20 is close to the fixed structure, the positioning groove 21 and the positioning post 11 are slightly aligned, the first magnet 30 on the fixed unit 10 is attracted to the second magnet 40 of the movable unit 20 and/or the additional fourth permanent magnet 34, at this time, the second magnet 40 is not operated, but the center position of the second magnet is provided with strong magnetic metal which can attract the first magnet 30, so that the equipment is assembled on the movable unit 20.

II, taking down: when the product is not carried or the movable unit 20 is to be taken down, the switch button 52 is operated to trigger the power supply electrifying device 50, the second magnet 40 generates a magnetic pole opposite to the first magnet 30, and then repulsion is generated, the magnetic force on the fixed unit 10 and the movable unit 20 becomes smaller, at this time, the movable unit 20 is taken down easily, and the experience that the clothes are obviously pulled and the clothes are difficult to take down is avoided.

In addition, it is worth noting that, since the fixing unit 10 is fixed, when the movable unit 20 is removed, the fixing unit 10 does not fall down to other parts of the clothes to cause inconvenience in removal.
