         2 . The hair straightener and curler according to  claim 1 , wherein both the first heating element ( 11 ) and the second heating element ( 12 ) can be extended in a length direction of the clamping plates, and the first heating element ( 11 ) and the second heating element ( 12 ) are at least partially overlapped in an extending direction. 
     
     
         3 . The hair straightener and curler according to  claim 2 , wherein the first heating element ( 11 ) can be arranged on at least one side of the second heating element ( 12 ). 
     
     
         4 . The hair straightener and curler according to  claim 3 , wherein the first heating element ( 11 ) is arranged on both sides of the second heating element ( 12 ), and the first heating surfaces ( 111 ) of the first heating elements ( 11 ) in the same clamping plate are arranged at the same height. 
     
     
         5 . The hair straightener and curler according to  claim 1 , wherein the second heating surface ( 121 ) can be arranged as an upwardly convex arc surface. 
     
     
         6 . The hair straightener and curler according to  claim 5 , wherein a third heating surface ( 21 ) can be arranged inside the accommodating cavity ( 22 ) for cooperating with the second heating surface ( 121 ). 
     
     
         7 . The hair straightener and curler according to  claim 6 , wherein the third heating surface ( 21 ) and the adjacent first heating surfaces ( 111 ) in the same clamping plate form an integrated structure. 
     
     
         8 . The hair straightener and curler according to  claim 1 , wherein the extension and retraction direction of the second heating element ( 12 ) is perpendicular to the first heating surfaces ( 111 ). 
     
     
         9 . The hair straightener and curler according to  claim 1 , wherein the hair straightener and curler further comprises a power assembly for driving the second heating element ( 12 ) to extend and retract, and the power assembly comprises:
 a hinged bracket ( 3 ) with a fixed end and a movable end, the fixed end is connected to the clamping plates, and the movable end is connected to the second heating element ( 12 ), and is extensible and retractable;   a driving member ( 4 ) is connected to the movable end of the hinged bracket ( 3 ), and the driving member ( 4 ) is movable between a third position and a fourth position; and   when the driving member ( 4 ) moves to the third position, the hinged bracket ( 3 ) drives the second heating element ( 12 ) to lower to the first position; and when the driving member ( 4 ) moves to the fourth position, the hinged bracket ( 3 ) drives the second heating element ( 12 ) to rise to the second position.   
     
     
         10 . The hair straightener and curler according to  claim 9 , wherein the hair straightener and curler further comprises a limiting member ( 5 ) arranged in the clamping plate, wherein the limiting member ( 5 ) is elastically movable in a direction perpendicular to a moving direction of the driving member ( 4 ), one of the limiting member ( 5 ) and the driving member ( 4 ) is provided with a protrusion, and the other thereof is provided with a groove that matches the protrusion.
