Disclosed is a quick coupler for a construction machine to allow the detachable attachment of attachments such as a bucket to the bottom of an arm. According to the present invention, the quick coupler for a construction machine to fixate an attachment to the bottom of a work tool includes: a coupler body connected to the bottom of the work tool, wherein a guide hole is formed in the coupler body in a horizontal direction; a first hook fixated to a connection pin horizontally moving along the guide hole to be locked to or unlocked from a first joint pin of the attachment; a second hook mounted on one side of the coupler body by a fixating pin to be rotated in order to be locked to or unlocked from a second joint pin opposed to the first joint pin; and a hydraulic cylinder of which one end is connected to the connection pin and the other end is connected to a predetermined position of the second hook. The hydraulic cylinder adjusts a distance between the first and second hooks to correspond to a distance between the first and second joint pins while driving, moves the first hook in a horizontal direction to lock or unlock the first hook to or from the first joint pin, and rotates the second hook around the fixating pin to lock or unlock the second hook to or from the second joint pin.
