Description

technical field

[0001] The invention relates to the field of locks, in particular to a lock and a speed reduction device thereof. Background technique

[0002] Existing ordinary mechanical locks use ordinary mechanical unlocking devices to open and close, which is poor in anti-replication and inconvenient to use. Therefore, smart locks are more and more convenient to use in people's lives. Application number: The invention patent of CN201821436638.X discloses the smart lock structure, which is described as follows; it has a motor, a shaft connected to the handle, and a housing. The shaft is assembled on the housing, and the clutch gear is assembled on the shaft. Under normal conditions, the clutch gear By disconnecting the clutch mechanism from the drive system of the motor, the rotation of the rotating shaft can be manually driven. The above solution is further as follows: the clutch mechanism is a compression spring, the compression spring is sleeved on the rotating shaft...
