The invention discloses a fingerprint door lock. The fingerprint door lock comprises a handle rotating shaft provided with a handle shaft body and an annular main body arranged on the peripheral surface of the handle shaft body in a sleeving mode, a clutch rotating shaft, and an elastic torsion component, wherein a limiting convex column extends out from the surface of the annular main body, and the handle shaft body is provided with a pin hole; the clutch rotating shaft is provided with a clutch pin which can be inserted into the pin hole and two limit wings with preset phase difference existing in the circumferential rotating direction, and the limit convex column is connected with one of the two limit wings so as to transmit torque between the handle rotating shaft and the clutch rotating shaft; the elastic torsion component is provided with two limiting support legs with preset phase difference; the elastic torsion component generates a restoring force which pushes the handle rotating shaft and the clutch rotating shaft to coaxially rotate until the limiting convex column and the two limit wings return to respective initial positions, so that the clutch pin and the pin hole arealigned in real time, and a door is stably and reliably opened.
本发明公开了一种指纹门锁，指纹门锁包括：把手转轴，把手转轴具有把手轴体和套设在把手轴体周面的环状主体，环状主体的表面伸出限位凸柱，把手轴体开设有销孔；离合转轴，离合转轴具有可插入销孔的离合销、在周向旋转方向上存在预设相位差的两个限位翼，限位凸柱与两个限位翼中的一个连接、以在把手转轴与离合转轴之间传递扭矩；弹性扭转部件，弹性扭转部件具有存在预设相位差的两个限位支脚；弹性扭转部件产生推动把手转轴和离合转轴同轴转动至限位凸柱和两个限位翼回复至各自的初始位置的回复力，从而使得离合销与销孔实时对准，从而稳定、可靠地将门打开。
