         2 . The automatic bending apparatus according to  claim 1 , wherein the body comprises casters mounted on the underside thereof so that the body is movable and a discharge hole formed on top thereof to discharge a bent copper pipe connector therethrough. 
     
     
         3 . The automatic bending apparatus according to  claim 1 , wherein the supply part comprises:
 a supply container located on the side portion of the body, wherein the supply container accommodates the copper pipe connector therein;   a plurality of ascending and descending bars vertically located on an inner side of the supply container, wherein the plurality of ascending and descending bars is configured to be moved up and down to allow the copper pipe connector accommodated in the supply container to be lifted above the supply container; and   a guide robot located above the body, wherein the guide robot is configured to hold the copper pipe connector placed on tops of the ascending and descending bars and is configured to move the copper pipe connector to the bending position adjusting part.   
     
     
         4 . The automatic bending apparatus according to  claim 3 , wherein the ascending and descending bars each have a concave grooves formed on top thereof such that the copper pipe connector is being able to be placed stably thereon. 
     
     
         5 . The automatic bending apparatus according to  claim 1 , wherein the bending position adjusting part comprises:
 a first cylinder;   seating stands located on one side of the top of the body, wherein the seating stands are linked to the first bending part and are configured to be moved by the first cylinder such that the copper pipe connector supplied from the supply part is seated thereonto; and   position adjusting rods located on both sides of top of the body, wherein the position adjusting rods is configured to adjust position of the copper pipe connector on the seating stands.   
     
     
         6 . The automatic bending apparatus according to  claim 5 , wherein the seating stands are spaced apart from each other by a shorter distance than a length of the copper pipe connector so as to allow the copper pipe connector supplied through the supply part to be seated thereonto and have seating grooves formed on one side thereof configured to prevent the copper pipe connector from moving or falling. 
     
     
         7 . The automatic bending apparatus according to  claim 6 , wherein the first bending part comprises:
 a first bending body located on top of the body in such a manner as to be linked to the seating stands;   a first support member located on top of the front surface of the first bending body in such a manner as to come into close contact with a portion of the copper pipe connector seated onto the seating stands;   a second cylinder; and   a first bending member connected to the front surface of the first bending body by means of a hinge in such a manner as to rotate around the hinge by the second cylinder, where in the first bending member is configured to bend one side of the copper pipe connector by rotation.   
     
     
         8 . The automatic bending apparatus according to  claim 7 , wherein the first support member has a first bending groove formed rounded on an outer side of the front surface thereof such that one side of the copper pipe connector is curvedly bent when the copper pipe connector is being bent by the first bending member. 
     
     
         9 . The automatic bending apparatus according to  claim 7 , wherein the second bending part comprises:
 a second bending body located on top of the body in such a manner as to face the first bending member;   a third cylinder;   rails located on the underside of the second bending body to move the second bending body by the third cylinder;   a second support member located on top of the front surface of the second bending body in such a manner as to come into close contact with a portion of the copper pipe connector seated onto the seating stands;   a fourth cylinder; and   a second bending member connected to the front surface of the second bending body by means of a hinge in such a manner as to rotate around the hinge by the fourth cylinder, wherein the second bending member is configured to bend the other side of the copper pipe connector by rotation.   
     
     
         10 . The automatic bending apparatus according to  claim 9 , wherein the second support member has a second bending groove formed rounded on an outer side of the front surface thereof such that the other side of the copper pipe connector is curvedly bent when the copper pipe connector is being bent by the second bending member. 
     
     
         11 . The automatic bending apparatus according to  claim 1 , further comprising angle adjusting stands located on side portions of the first bending part and the second bending part, wherein the angle adjusting stands are configured to adjust rotation angles of the first bending member and the second bending member before bending according to bending curvature angles of the copper pipe connector.
