At present, an electric control lock generally uses a locking hook and a locking bolt to cooperate for locking and unlocking, and the locking bolt is controlled to move through an electric drive element. During unlocking, the card reader is required to send an unlocking instruction to the electric control lock, and the purpose of unlocking is achieved by controlling the movement of the lock bolt. In order to prevent the lock bolt from moving, it is common practice to provide a spring between the lock bolt and the lock body, so as to prevent the lock bolt from moving by itself. And when the electric control lock is locked after being unlocked, the spring can provide elastic force for the lock bolt, so that the lock bolt moves towards the lock hook and is clamped with the lock hook, and automatic locking is realized.

Although the above electric control lock can utilize the elasticity of the spring to ensure that the lock bolt can not move by itself within a certain limit, the following problems still exist: when the force provided by the external vibration to the lock bolt is just the moving direction of the lock bolt during unlocking and is greater than the elastic force of the spring, the lock bolt can move under the action of the external force, and the lock bolt is unlocked mistakenly.

4. The multi-function rotating member of claim 3, wherein: when the connecting part rotates to a first direction, the shortest distance between the second protruding part and the second inner side wall is greater than or equal to 0 and smaller than the distance that the first protruding part pushes the first component to move.

5. The multi-function rotary member as claimed in any one of claims 2 to 4, wherein: also includes a positioning part; when the connecting part moves to a first direction or a second direction, the positioning part limits the connecting part to continue rotating; the positioning part comprises a first protruding part and a second protruding part; when the connecting part rotates to a first direction, the first protruding part rotates to a position for limiting the first protruding part to continue rotating or contacts with a travel switch for controlling the rotation of the connecting part; when the connecting part rotates to the second orientation, the second bulge rotates to a position for limiting the second bulge to continue rotating or rotates to be contacted with another travel switch for controlling the rotation of the connecting part.

6. The multi-functional rotating member of any one of claims 1 to 4, wherein: also includes a positioning part; when the connecting part moves to the first direction or the second direction, the positioning part limits the connecting part to rotate continuously.

7. The multi-function rotating member of claim 6, wherein: the positioning part comprises a third bulge arranged along the axial direction parallel to the connecting part, when the connecting part moves to the first direction, the third bulge rotates to a position for limiting the third bulge to continue rotating or rotates to be in contact with one travel switch for controlling the connecting part to rotate, and when the connecting part moves to the second direction, the third bulge rotates to another position for limiting the third bulge to continue rotating or rotates to be in contact with another travel switch for controlling the connecting part to rotate.

8. The multi-functional rotating member of any one of claims 1 to 4, wherein: the connecting part is provided with a groove/hole matched with the driving part along the axial direction; the driving part is used for driving the connecting part to rotate.

9. An electronic unlocking mechanism, comprising: comprising a motor, a lock bolt and the multifunctional rotating part of any one of claims 1 to 8; an output shaft of the motor is connected with the connecting part and drives the connecting part to rotate; the lock bolt adopts the first part of any one of claims 1 to 8; when the electronic unlocking mechanism is locked, the multifunctional rotating piece limits the movement of the lock bolt through the limiting part; when the electronic unlocking mechanism is unlocked, the multifunctional rotating piece drives the lock bolt to move through the driving part.

10. The electronic unlocking mechanism of claim 9 wherein: also includes a first elastic element; when the connecting part rotates from a first orientation to a second orientation, the driving part drives the lock bolt to move towards the first elastic element, and the first elastic element is in a compressed state: when the connecting part rotates from the second orientation to the first orientation, the first elastic element pushes the lock bolt to move towards the direction far away from the first elastic element through elastic force.
