At this time, the rotation shaft of the drive module is inserted into the shaft coupling hole of the rotation shaft member and then is shaft-coupled to the rotation shaft member, so that the rotation shaft member can rotate together with the rotation of the drive module.

Here, the cross section of the rotation axis of the drive module has a polygonal shape, and the inner diameter of the shaft coupling hole of the rotation axis member also has a corresponding shape, so that the rotation axis of the drive module and the rotation axis member are stably coupled and synchronized with the rotation of the drive module. Rotation of the rotating shaft member becomes possible.

Here, stable fixation between the rotation axis of the drive module and the rotation axis member can be achieved by tightening bolts, etc. With this combination method, the drive module can transmit rotational force no matter which side of the pair of hinges it is mounted on, allowing the user to change the mounting position of the drive module depending on the movement of the left or right hand, making use more convenient. This becomes possible.

Meanwhile, the guide protrusion is formed radially outward from the rotation axis of the rotation axis member. That is, it is formed to protrude from the plate surface of the rotation shaft member at a position eccentric radially outward from the rotation axis of the drive module and the rotation shaft member.

Also, one side of the guide link is rotatably coupled to the rear side of the main body, and the other side is coupled to the other side of the rotation bracket to be able to slide along the rotation bracket.

Here, an arc-shaped guide groove that reciprocates with the guide protrusion inserted is formed in the guide link.

Meanwhile, a sliding protrusion protruding toward the rotation bracket may be formed on the other side of the guide link. Additionally, a sliding groove formed along the longitudinal direction may be formed on the other side of the rotation bracket. Through this, the sliding protrusion is inserted into the sliding groove of the rotary bracket and is coupled to enable reciprocating movement along the longitudinal direction of the rotary bracket.

Also, for example, the rotation axis on one side of the guide link according to an embodiment of the present invention is formed on the main body, that is, on the side wall, at a predetermined distance forward from the rotation axis of the rotation bracket.

At this time, the shape of the guide link is provided in a shape corresponding to the arc shape of the guide groove, so that the other side can be coupled to the other side of the rotation bracket. Here, the other side of the guide link is coupled to the other side of the rotation bracket so as to be slidable along the longitudinal direction of the rotation bracket, as described above.

Meanwhile, the main body according to an embodiment of the present invention may further include a bar insertion portion and a fixing unit.
