Abstract
This invention concerns about a tubular door lock which makes use of humps attached on a cylinder for guiding and restricting the movement of a rotating shell and an extending shell enabling assembling plates hooked with the bottom of the extending shell to alter the position of the center of a fan-shaped gear on it so that the teeth of the fan-shaped gear can engage with those of the dead bolt to make up an action of pulling the dead bolt back.
