     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The present invention will be further explained in conjunction with the accompanying drawings. 
     As shown in  FIG.  1    to  FIG.  3   , the multifunctional hair straightening and curling device includes an upper main body  1 , a lower main body  3  and a handle  6 . The upper main body  1  and the lower main body  3  are disposed oppositely, and one end of each of the upper main body  1  and the lower main body  3  is mounted on the end part of the handle  6 . An upper heating body  2  and a lower heating body  4  are disposed between the upper main body  1  and the lower main body  3  respectively. The upper heating body  2  is disposed on the upper main body  1 , and the lower heating body  4  is disposed on the lower main body  3 . One end of the upper heating body  2  and one end of the lower heating body  4  are rotatably connected by a rotary shaft  7 . A button  8  is disposed on the upper main body  1 . An elastic component is arranged in the upper heating body  2  and the lower heating body  4 . After the upper heating body  2  and the lower heating body  4  are opened and release the hair, the button controlling the upper heating body  2  and the lower heating body  4  to be opened is loosened, and the upper heating body  2  and the lower heating body  4  automatically clamp the hair. The button  8  is capable of controlling the upper heating body  2  and the lower heating body  4  to perform opening-closing movement. The upper surface of the upper main body  1  is provided with first air outlets  101 , and the upper main body  1  is provided with a first air outlet passage  102  therein. The lower surface of the lower main body  3  is provided with second air outlets  301 , and the lower main body  3  is provided with a second air outlet passage  302  therein. The handle  6  is provided with a fan  5  therein. The fan  5  is capable of blowing generated wind out from the first air outlets  101  through the first air outlet passage  102 . The fan is capable of blowing the generated wind out from the second air outlets  301  through the second air outlet passage  302 . 
     According to the present invention, the upper surface of the upper main body  1  is provided with the first air outlets  101 , and the upper main body  1  is provided with the first air outlet passage  102  therein. The lower surface of the lower main body  3  is provided with the second air outlets  301 , and the lower main body  3  is provided with the second air outlet passage therein  302 . The handle  6  is provided with the fan  5  therein.

The hair is heated by the upper heating body  2  and the lower heating body  4 , and is then wound on a cylindrical body combined by the upper main body  1  and the lower main body  3 . Under the radiating action of wind, the hair is cooled and set instantly, and moves toward the direction opposite to hair roots. The multifunctional hair straightening and curling device will generate a continuous hair curling effect, and thus saves a lot of time. Multiple different hair set effects can be curled according to the moving speed of the multifunctional hair straightening and curling device. 
     Further, the upper heating body  2  and the lower heating body  4  are capable of opening for a certain angle, and the vertical width between the upper heating body  2  and the lower heating body  4  ranges from 1 mm to 8 mm. 
     As shown in  FIG.  4    to  FIG.  5   , the upper heating body  2  and the lower heating body  4  are connected in a scissor shape by a rotary shaft  7 . A rotary handle  9  is disposed on the right end of the upper heating body  2  and the lower heating body  4 . The left end of the rotary handle  9  is provided with a boss part  91  capable of abutting against the right end of the lower heating body  4 . The right end of the rotary handle  9  is provided with an extending part  92  capable of abutting against the right end of the upper heating body  2 , and the extending part  92  is bent rightwards and extends upwardly and is connected to the lower end of the button  8 . 
     During the use of the present invention, the button  8  is pressed, and the button  8  downwardly pushes the extending part  92  of the rotary handle  9 , so as to drive the rotary handle  9  to rotate clockwise. When the rotary handle  9  rotates clockwise, the boss part  91  of the rotary handle  9  upwardly pushes the lower heating body  4  to rotate counterclockwise around the rotary shaft  7 , so that the lower heating body  4  is opened downwardly. While the rotary handle  9  rotates clockwise, the extending part thereof also pushes the upper heating body  2  to rotate clockwise around the rotary shaft  7 , so that the upper heating body  2  is upwardly opened. 
     The foregoing is not limitative to the technical scope of the present invention in any way. Any amendments, equivalent changes and modifications made on the above embodiments according to the technical essence of the present invention all belong to the scope of the technical solution of the present invention.
