The parts to be connected to the front lock body are relatively light and can generally be made of plastic materials. Therefore, the threaded column used to connect with the password disk, fingerprint and front circuit board can be integrally injection molded, but the clutch mechanism and the motor are heavy, so it is generally necessary to select sheet metal parts, on which corresponding threaded columns are welded for installing structures such as the clutch mechanism and the motor. Welding requires manual welding, which is difficult to produce, has low assembly efficiency, high welding cost and is prone to being unstable. On the other hand, the sheet metal parts of the rear lock body are thin and easy to be welded through, resulting in overall scrapping. Summary of the invention
