ABSTRACT:
This invention relates to a tubular door lock which mainly includes a basic shell, an extending shell, a dead bolt, two assembling plates, a safety bolt, a locking plate and an unlocking plate. Through apertures, notches and holes disposed thereon, it can connect seletively together in a short (60 mm) or long (70 mm) position, and is therefore able to change the distance between the knob and the faceplate of the lock via adjustment of the extending shell.
