a first lock bolt and a second lock bolt, wherein when the first lock bolt and the second lock bolt retract, the door leaf is unlocked;
a first electric driver, wherein when the first electric driver operates, the first lock bolt is driven to retract; and
a lever component, wherein the lever component is operated outside the door leaf to retract the second lock bolt;
wherein the lever component is configured to tilt around a fulcrum, and the lever component comprises an inner end and an outer handle; the inner end of the lever component is drivingly connected to the second lock bolt; the outer handle of the lever component is configured to receive a pressing action of a hand; when the outer handle of the lever component is pressed, the lever component tilts, allowing the inner end to drive the second lock bolt to retract; the outer handle of the lever component is provided with a pickup device for picking up a biological signal of a finger; the pickup device is in electrical signal connection with a controller; the controller is configured to control the first electric driver to operate; when the finger exerts the pressing action such that the lever component tilts to retract the second lock bolt, the pickup device synchronously picks up the biological signal of the finger; and when the biological signal of the finger is determined as an authorized signal, the controller controls the first electric driver to operate to drive the first lock bolt to retract, thereby unlocking the door leaf.
