Hair pin

Abstract

The present invention relates to a hair pin capable of holding hair in a bundle form, in which a connection region of a joint device connected to an upper gripper is in a non-contact state at an upper portion of an pushing part of the upper gripper, so that frequent breakage of the connection region of the joint device, which occurs in a conventional hair pin that is manufactured in a small size, can be prevented from occurring. In the hair pin, a lower gripper and an upper gripper are coupled to each other in a form of a gripper through lower and upper hinge parts, a collecting part is rotatably connected to a front end of the upper gripper, and a joint part is connected between the collecting part and the upper gripper.

What is claimed is: 
     
         1 . A hair pin in which a lower gripper and an upper gripper are coupled to each other in a form of a gripper through lower and upper hinge parts, a collecting part is rotatably connected to a front end of the upper gripper, and a joint part is connected between the collecting part and the upper gripper,
 wherein the upper gripper is provided with a separation preventing part protruding forward of an upper pushing part in a ‘reverse-L’ shape to prevent a hinge shaft part of the joint part from being separated, and   the joint part includes:
 a pair of guide parts formed at both ends of the joint part; 
 the hinge shaft part formed at rear ends of the guide parts while being disposed inward of the separation preventing part of the upper gripper, and restrained so as not to be separated to an outside of the joint part; and 
 a latching shaft formed inward of U-shaped front ends of the guide parts and fitted into a connection groove of the collecting part. 
   
     
     
         2 . The hair pin of  claim 1 , wherein the upper gripper includes:
 an upper pressing part for pressing hair;   the upper pushing part for widening or narrowing the upper pressing part about a shaft pin;   an upper hinge part coupled with a lower hinge part of the lower gripper;   the separation preventing part protruding forward of the upper pushing part in a ‘reverse-L’ shape to prevent a hinge shaft part of the joint part from being separated; and   a coupling part formed at a front end of the upper pressing part and coupled to an end of an extension part of the collecting part.
