Abstract
A door lock includes a lock with a latch. An inside face plate and an outside face plate of the door lock are respectively mounted to an inside plate and an outside plate of the door lock. A washer plate is sandwiched between the inside face plate and the outside face plate. An inside cylinder and an outside cylinder are connected between the inside plate and the outside plate. An inside collar is connected between the inside face plate and the inside cylinder, and an outside collar is connected between the outside face plate and the outside cylinder. When the door lock is set in ready-to-open mold, the door can be opened by either rotating the shafts or the door handle by one hand. When the door lock is set in locked mold, the door cannot be opened by simply rotating the door handle.
