         2 . The hair curler according to  claim 1 , wherein one end of the at least one first connecting rod ( 31 ) is a limited end (A), and the limited end (A) can only rotate around a connection point, or move close to the hinge shaft ( 32 ) in the second direction while rotating around the connection point. 
     
     
         3 . The hair curler according to  claim 2 , wherein the limited end (A) is rotationally connected to the sliding groove ( 22 ) or to the housing ( 1 ). 
     
     
         4 . The hair curler according to  claim 1 , wherein the hinge shaft ( 32 ) is limited to movement in the first direction only. 
     
     
         5 . The hair curler according to  claim 1 , wherein the hair curler further comprises a chute ( 4 ), wherein the chute ( 4 ) is connected to the driving assembly ( 3 ) and formed on the housing ( 1 ) to provide a track of movement in the second direction. 
     
     
         6 . The hair curler according to  claim 1 , wherein the hair curler further comprises a braking member ( 5 ), wherein the braking member ( 5 ) is connected to the driving assembly ( 3 ) for driving the driving assembly ( 3 ) to move. 
     
     
         7 . The hair curler according to  claim 6 , wherein the hair curler further comprises a second connecting rod ( 6 ), wherein one end of the second connecting rod ( 6 ) is connected to the braking member ( 5 ), and the other end thereof is connected to the driving assembly ( 3 ). 
     
     
         8 . The hair straightener and curler according to  claim 7 , wherein the braking member ( 5 ) is slidably connected to the housing ( 1 ), one end of the second connecting rod ( 6 ) is rotationally connected to the braking member ( 5 ), and the other end thereof is rotationally connected to a free end of the first connecting rod ( 31 ). 
     
     
         9 . The hair straightener and curler according to  claim 7 , wherein when the first heating element ( 2 ) is in a state of a limit position of moving up or down, the second connecting rod ( 6 ) form a first preset comprised angle or a second preset comprised angle with the second direction, respectively. 
     
     
         10 . The hair curler according to  claim 1 , wherein the hair curler further comprises second heating elements ( 7 ) respectively arranged on two sides of the first heating element ( 2 ), and each of the second heating elements ( 7 ) is fixedly connected to the housing.
