An innovated doorknob structure consisting of a main unit, a handle, an arrester plate, a spindle and an elastic member is assembled on one side of a door panel. The handle is capable of being turned and has one end inserted and hinged in the main unit. The arrester plate is assembled on the main unit to arrest the handle, and is engaged with the hinge of the handle, so the handle is capable of turning but not falling off from the main unit. The spindle and the elastic member are assembled to one end of the handle that is located inside the main unit. When the handle is turned, the spindle is pushed away from the handle; thereby one end of the spindle drives another doorknob structure, releasing the engagement between the doorknob and the doorframe to open the door panel. The foregoing configuration is simplified operation of opening a door by turning the handle.
