A door lock for a handle, comprises a housing, a rotatable connector inside the housing, a first elastic element and a second elastic element both arranged inside the housing. The rotatable connector is interacted with the handle. The first elastic element is at least configured to provide a restoring force for the handle to return to its origin position when the handle is rotated upward to lock the door, and the second elastic element is configured to provide a restoring force for the handle to return to its origin position when the handle is rotated downward to unlock and open the door, as well as to provide enough resistance to remain handle at its origin position when the handle is released. The door lock is effort-saving for the users to rotate the handle upward, and also adapted for various handles having different weights, to be remained at the origin position when the handle is released.
