Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0017] The components of this application, including the smart door lock 1, camera 2, password input panel 3, NFC reader 4, handle 5, fingerprint recognition module 6, fixing cylinder 7, cover 8, speaker 9, microphone 10, rubber pad 11, keyhole 12, microprocessor 13, GSM communication module 14, torsion spring 15, tactile switch 16, rotating rod 17, stop block 18, and rotating sleeve 19, are all general standard parts or parts known to those skilled in the art. Their structure and principle are common knowledge and can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0018] Example 1: Please see Figures 1-5As shown, this utility model provides a lock body with modular certification, including a smart lock 1. A camera 2 is fixedly installed on the upper end of the front surface of the smart lock 1. A lock hole 12 is provided at the lower end of the smart lock 1. A fixed cylinder 7 is fixedly connected to the lower end of the smart lock 1 and above the lock hole 12. A rotating rod 17 is movably sleeved between the middle ends of the two sides of the fixed cylinder 7. A cover 8 is fixedly connected to the front surface of the rotating rod 17 and in front of the lock hole 12. A rotating sleeve 19 is fixedly connected to the middle end of the rotating rod 17. The two sides of the rotating sleeve 19 are movably connected to the fixed cylinder. A torsion spring 15 is fixedly installed between the surface of the rotating sleeve 19 and the inner cavity of the fixed cylinder 7. A tactile switch 16 is fixedly installed at the right end of the back of the fixed cylinder 7. A microprocessor 13 is fixedly installed at the lower end of the inner cavity of the smart lock 1 and below the lock hole 12. A GSM communication module 14 is fixedly installed at the lower end of the inner cavity of the smart lock 1 and below the microprocessor 13. A speaker 9 is fixedly installed at the lower end of the left side of the outer surface of the smart lock 1. A microphone 10 is fixedly installed at the lower end of the front surface of the smart lock 1 and below the cover 8.

[0019] In this technical solution, the cover 8 provides protection on the front of the keyhole 12.
