The present invention provides a handle replacement type device for opening and closing a door, which includes: a door lock releasing unit which is installed in a door and opens and closes the door by using received power; a push-and-pull unit which is installed on the door while being able to move within a section in order to transmit the power to the door lock releasing unit; and a handle unit which is detachably coupled to the push-and-pull unit. According to the present invention, the device can easily replace the handle by changing the handle to various shapes capable of making a user easily press and pull the handle in correspondence with a structure of opening the door by pressing and pulling the door in an opening direction. The device can also replace the handle to another handle of various designs including character images, beautiful images, logos, and marks to fit the indoor interior environments and situations from time to time, thereby providing decorative and advertisement effects. The device can simplify the structure of the door lock releasing unit by using a slide guide unit which converts the power to be in a direction perpendicular to a section movement direction and a sliding unit moving within a section along the slide guide unit. The device can also significantly reduce the number of components, ensures an easy assembly process to increase productivity, and reduce the product cost to enhance marketability. |
