Abstract: A mechanical-magnetic locking device includes a first connecting component, a second connecting component and a magnet-armature structure. The first connecting component is provided with a locking element with a gap. The second connecting component is provided with a locking member matched with the locking element with the gap. A magnet is provided in one connecting component and an armature is provided in the other connecting component. The locking element with the gap is coupled with the magnet and the armature is coupled with the locking member. When opening the locking device, the magnet and the armature are relatively moved to each other, and the magnetic attracting area is substantially unchanged or increased, allowing the locking element with the gap and the locking member to move from the engaged position to the non-engaged position.

Abstract: The present invention provides a lacing system based on a rotor and a stator and the use method thereof, including a rotor and a stator. The rotor includes a winding slot. The rotor is provided with a tooth, and the stator is correspondingly provided with a pawl. Both of the stator and the rotor are respectively provided with a gear structure, and the pawl and the tooth engage or disengage through the gear structure. The lacing system and the use method thereof provided by the present invention solve the problems of complex structure, single function, low production efficiency and so on, and achieve the advantages of diversified functions, attractive appearance, compact structure and so on, meeting the requirements of people pursuing a healthy and convenient life.
