The door opening handle has various structural forms, and the handle is L-shaped, and the handle structure can only rotate at a small angle (generally smaller than 90 degrees), so that the handle structure can only drive the bolt head to move for a short distance, and the handle can rotate at 360 degrees to ensure the bolt opening depth for enhancing the locking length of the bolt head, so that the round handle is required to operate. That is, the existing lock structure can only adapt to the handle with one rotation angle, cannot be used commonly, does not form modularization, and needs to design different locks according to different requirements.
The electromagnetic iron core that traditional electronic safe's electronic lock was used is direct with the sideslip contact, and the handle is direct links to each other with the plectrum, consequently just must have when the handle rotates and drive plectrum pivoted trend, in this case, in case, the time spent hard of turning the handle, the plectrum can drive the side slide striking electromagnetic iron core, damages electromagnetic iron core, causes the safe to damage, or makes the sideslip directly slide electromagnetic iron core, makes the door open, causes the potential safety hazard.
