Abstract: A door handle module and a door lock using the same are disclosed. The door handle module according to the present invention is provided with a hollow rotating piece, a torsion spring enclosing an outer circumference of the rotating piece and being engaged with the locking protrusion formed in the mounting recess by both ends thereof, and a hollow operating piece being fixed to the outside of the rotating piece and includes a shoulder edge formed on a circumference thereof to mount the both ends of the torsion spring and an operational edge formed on an inner circumference thereof to be connected to the handle. Accordingly, the handle that has been turned to open the door can be turned back by a recovery force of the torsion spring so as to be able to maintain its neutral position, and the structure of the door handle module and the door lock can be simplified.

Abstract: The present invention relates to a convertible door lock device with a removable supporting pipe, which guarantees compatibility in construction according to a type of a door, being capable of selectively employing a movement preventing structure implemented by a supporting pipe according to the door type. The door lock device according to the embodiment of the present invention comprises the supporting pipe constituted by a pipe body including a fastening hole therein and a head part formed at one end of the pipe body, and a seating recess formed on an inner surface of the outer bracket for selective insertion of the head part of the supporting pipe. The head part of the supporting pipe is inserted in the seating recess of the outer bracket and the pipe body is inserted in a supporting hole dedicatedly formed on the door at a position outer than the mounting hole to be bolt-connected at the inside of the door through the fastening hole.
