The lock tongue retracts to drive the outer handle to rotate when the door is opened, so that the unlocking process is clearly shown to a user, and maintenance personnel can conveniently remove faults.

The lock tongue portion is a lock core structure which is commonly used in door locks used in the prior art.

Specifically, the touch key comprises a base, a base and a prism box, wherein the prism box is arranged on the base, the upper surface of the prism box is used for reading a fingerprint image when a finger touches the fingerprint box, a light source is arranged in the prism box, and a right-angle prism, a distortion correcting prism and a reflector which are sequentially connected with an optical circuit of the light source are arranged in the prism box; the touch key structure further comprises an imaging objective lens assembly and a charge-coupled device, wherein the charge-coupled device is connected with the imaging objective lens assembly. The CCD is used for converting the optical image of the fingerprint into a video signal and transmitting the video signal to the communication device. And sending the signal to a remote management system by the communication device. The fingerprint is collected through the touch key and sent to the remote management system through the communication device, and the collected fingerprint is compared with a fingerprint library prestored in the remote management system, so that whether the electronic lock structure is authorized to be opened or not is determined.

Preferably, the number of the touch keys is 9. Because each touch key is provided with the fingerprint acquisition device, when a user inputs a multi-digit password, the user fingerprints are acquired for many times. Therefore, the accuracy of identity verification is improved.
