By adopting the above structure, the rotation of the locking claw is controlled by the solenoid valve and the dial plate to unlock the card plate for electric opening, and the rotation of the locking claw is controlled by the inner lock core, the outer lock core and the pull rod to unlock the card plate for manual opening. While ensuring the stability of the structure, the structure is simplified and the applicability and safety are enhanced.

[0005] Preferably, a torsion spring is sleeved between the rotating shaft and the mounting plate, a lever arm is provided on the rotating shaft, a riveted long hole is provided at one end of the pull rod facing the lever arm, and the pull rod is riveted to the lever arm through the riveted long hole. With the above structure, the riveted long hole can play a buffering role when locking, avoiding the pull rod from being deformed due to stamping when locking, thereby increasing the service life.

[0006] Preferably, the bottom plate is covered with a pressure plate on the upper side of the clamping plate and the locking claw. The above structure can ensure the structural stability between the clamping plate and the locking claw, and avoid the situation that the clamping plate cannot be clamped with the locking claw after long-term use.

[0007] Preferably, the bottom plate is provided with a micro switch on the side of the card away from the stop claw, and the micro switch and the solenoid valve are connected to a controller through a harness assembly. With the above structure, the state of the card is confirmed by the micro switch, making the feedback of the card state clearer.

[0008] The utility model has the advantages of simple structure, reasonable design, simple operation, safety and stability, and can be opened manually or electrically. BRIEF DESCRIPTION OF THE DRAWINGS
