[0002] Full-automatic lock body usually refers to the lock body that main lock tongue and bevel lock tongue can automatically retract or extend after verification succeeds. The working principle of full-automatic lock body mainly depends on the cooperation of motor and transmission device. When the user verifies the identity through password, fingerprint, mobile phone APP and the like, the control system receives the signal and gives the instruction, the motor starts to drive the transmission device, so that the lock tongue retracts or extends, thereby realizing the unlocking or locking.

[0008] The main lock tongue pushing block is arranged on the main lock tongue assembly, and the spring is sleeved on the separation rotating block.

[0009] The gear pushing plate and the square core rotating block are arranged on the clutching plate.

[0010] Further improvement lies in that a group of lock posts are arranged on the main lock tongue assembly.

[0011] Further improvement lies in that a group of holes are arranged on the lower cover assembly to match the lock posts.

[0012] Further improvement lies in that a group of large teeth are arranged on the main lock tongue push block, and a meshing slot one is arranged on the side of the main lock tongue assembly to match the large teeth.

[0013] Further improvement lies in that a group of small teeth are arranged on the main lock tongue push block, and a meshing slot two is arranged on the side of the gear push plate to match the small teeth.

[0014] Further improvement lies in that a pair of guide posts are arranged on the lower cover assembly on the side away from the clutch push plate, and sliding grooves are arranged on the two ends of the clutch push plate away from the main lock tongue assembly.

[0015] Further improvement lies in that after the clutch push plate is installed on the lower cover assembly, the pair of guide posts are located in the sliding grooves respectively.
