| 摘要 |
The present invention relates to a magnet fixed block, and, more specifically, to a technology to improve the magnetism on/off control structure of an internal magnet, to realize a main frame with nonmagnetic materials, and to reduce the total weight. As well, as the main frame is realized with nonmagnetic materials and is made lighter, production can be easier than before. The movement of position in the process of use is easier and the convenience of use is improved. Accidents during movement can also be prevented. In addition, the present invention prevents magnetism from being formed on an unnecessary point of the main frame and prevents other magnetic metal articles from sticking to the main frame. |
