As shown in fig. 15 and 16, the housing 16 is further provided with a corner limiting table 162, and the reversing column 15 and the corner limiting table 162 can abut against each other in the rotation direction of the handle rotation shaft 11 to form a corner limiting for the handle 12, so that the rotation angle of the handle 12 of the fingerprint door lock 10 that is lifted up or pressed down can be effectively limited, that is, when the door lock is opened or closed after being lifted up or pressed down and the handle 12 is continuously lifted up or pressed down, the clamping wing abuts against the reversing column 15, so that the handle rotation shaft 11 is blocked by the reversing column 15 to continuously rotate, and further, the door lock failure caused by excessive lifting up or pressing down is effectively avoided.

In a specific embodiment, the fingerprint door lock 10 further includes a clutch driving member 19, the clutch driving member 19 has a retractable driving portion, the clutch rotating shaft 13 is provided with a clutch pin 131, the outer peripheral surface of the handle rotating shaft 11 is provided with symmetrically arranged pin holes 1111, and the clutch rotating shaft 13 drives the clutch pin 131 to enter and exit the pin holes 1111 through the retractable driving portion, so as to achieve disconnection between the clutch rotating shaft 13 and the handle rotating shaft 11.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
