The present invention provides a door lock device having an inner side main body capable of releasing automatically a forced locking set of a locking unit when an door inner side handle is rotating, including a rotation drive part arranged on the inner side main body rotatablely and connected with the door inner side handle; a first bar part capable of contacting with the rotation drive part and rotating toward a direction when contacting along the rotation of the rotation drive part; a forced locking bar arranged on the inner side main body, capable of moving in a straight-line back and forth in a right-and-left, for setting or releasing the forced locking state of the locking unit according to different movement positions; and a second bar part, arranged on the inner side main body rotatablely, rotating through the first bar part and changing the position of the forced locking bar. Under the forced locking state, the moving directions of the second bar part and the forced locking bar are parallel, such that it is capable of moving the forced locking bar to the position for releasing the forced lock by using a less external force comparing with the existing technique.
