Abstract

A magnetic buckling device comprises a housing, a main plug, a main sliding seat, two main components, and a control component. The main plug can be inserted into the housing for being buckled. The main sliding seat and the housing can move or rotate relative to each other so as to bring the main plug into an unlocking state. The two main components are respectively disposed on the main sliding seat and the main plug. When the main plug approaches to a main plug hole of the housing, a magnetic attraction force is generated between the two main components to guide the main plug to be closer to the main plug hole of the housing and enable the main plug to be inserted into the main plug hole. After the main plug is inserted, the magnetic attraction force between the two main components will also assist in retaining the main plug in a buckled state so as to improve the convenience of use. The control component selectively prevents the main sliding seat and the housing from moving or rotating relative to each other so as to avoid unlocking. When it is desired to withdraw the main plug, the control component can drive the main sliding seat and the housing to move or rotate relative to each other.
