The utility model provides a hair is received space (19) and is provided modified human engineering that flexibly convolutes around a section of thick bamboo (16) and sends out curly hair hair iron (1, 401) of tuft (20), and it gets into through providing opening (18) that form through main part (11, 411) around main part (11, 411) of a section of thick bamboo (16). Opening (18) provide the passageway that is used for the hair to include the circumference part (18a) of extending around the distal end (16b) of a section of thick bamboo (16) and from circumference part (18a) towards the axially extended slot part of near -end (16a) (18b). Slot part (18b) is set up the vertical tip department at curly hair hair iron (1) to it is on a parallel with the groove extension and by traverse push tuft (20) to be configured as to be used for receiving. The finger -like piece can be installed main part (11, 411), and it is stuck out with common closed slot part (18b) and will send out tuft (20) and keeps in space (19) are received to the hair. The finger -like piece can flexibly be deflected to be passed through in order to allow sending out tuft (20).
