Automatic Pop-Open Hair Clip

Abstract

An automatic pop-open hair clip, which comprises a first clip body, a second clip body, and a helical clutch shaft; the helical clutch shaft is pivotally set between the first clip body and the second clip body, capable of providing the spring force necessary for the automatic pop-opening of the first and second clip bodies; the helical clutch shaft includes a first shaft body, a second shaft body, a cap, a resilient telescopic torsion element, and a shaft; when the user presses both the first and second clip bodies at the same time, the helical clutch shaft can perform a multi-stage closing and clamping operation, and when the user presses both ends of the helical clutch shaft simultaneously, the aforementioned resilient telescopic torsion element can automatically cause the first and second clip bodies to pop open.

I claim: 
     
         1 . An automatic pop-open hair clip, comprising
 a first clip body ( 1 ), a second clip body ( 2 ), and a helical clutch shaft ( 3 ); wherein   the first clip body ( 1 ) and the second clip body ( 2 ) are disposed correspondingly and can rotate relatively to jointly clamp an object;   the helical clutch shaft ( 3 ) is pivotally disposed between the first clip body ( 1 ) and the second clip body ( 2 ), capable of providing a spring force for the automatic pop-open of the first and second clip bodies;   the helical clutch shaft includes a first shaft body ( 31 ), a second shaft body ( 32 ), a cap ( 33 ), a resilient telescopic torsion element ( 34 ), and a shaft ( 35 );   one side of the first shaft body ( 31 ) connects to the first clip body ( 1 ), and along the axis direction, is sequentially provided with a first stop piece ( 311 ), a first helical rack ( 312 ), a guide part ( 313 ), with a first wing part ( 314 ) at the connection point with the first clip body;   one side of the second shaft body ( 32 ) connects to the second clip body ( 2 ), and along the axis direction, is sequentially equipped with a second stop piece ( 321 ), a spacer part ( 322 ), a second helical rack ( 323 ), a sleeve ( 324 ), with a second wing part ( 325 ) at the connection point with the second clip body;   the second stop piece ( 321 ), located outside the first stop piece ( 311 ), serves as a restraint for the use of the first stop piece;   the spacer part ( 322 ) accommodates the first stop piece ( 311 ) and the first helical rack ( 312 ), enabling both to move along the axis within this space;   a first tooth part ( 3121 ) of the first helical rack ( 312 ) is positioned on the side of the first shaft body ( 31 ) away from the first wing part ( 314 );   a second tooth part ( 3231 ) of the second helical rack ( 323 ) is positioned on the side of the second shaft body ( 32 ) away from the second wing part ( 325 );   the first and second tooth parts ( 3121 ,  3231 ) are correspondingly positioned and can interlock with each other;   the cap ( 33 ), positioned at the free end of the guide part ( 313 ), corresponds to the sleeve ( 324 ) and fits over the sleeve ( 324 ), with one side corresponding to the free end of the first wing part ( 314 ) being provided with a third wing part ( 331 ) that can be positioned on the first wing part ( 334 );   the resilient telescopic torsion element ( 34 ), placed between the sleeve ( 324 ) and the cap ( 33 ), with both ends respectively pressing against the sleeve and the cap, utilizes the spring force to provide the meshing force between the first helical rack ( 312 ) and the second helical rack ( 323 ), enabling the helical clutch shaft ( 3 ) to disengage during pressing;   the shaft ( 35 ) passes through the first stop piece ( 311 ), the second stop piece ( 321 ), crosses over the spacer part ( 322 ), the second helical rack ( 323 ), and secures at the top end of the sleeve ( 324 ).   
     
     
         2 . The automatic pop-open hair clip according to  claim 1 , wherein the sleeve ( 324 ) has an inner bottom surface corresponding to the resilient telescopic torsion element ( 34 ), further provided with a first coupling groove ( 3241 ) for engaging and positioning an end of the resilient telescopic torsion element ( 34 ); the inner bottom surface of the sleeve ( 324 ) corresponding to the resilient telescopic torsion element ( 34 ) is also provided with a second coupling groove ( 332 ) for engaging and positioning an end of the resilient telescopic torsion element ( 34 ). 
     
     
         3 . The automatic pop-open hair clip according to  claim 2 , wherein the connection between the first clip body ( 1 ) and the first shaft body ( 31 ) is equipped with a first slot ( 11 ) for engaging and positioning with the first wing part ( 314 ), and the first clip body ( 1 ) at the location corresponding to the second stop piece ( 321 ) is further equipped with a first pressing piece ( 12 ); the connection between the second clip body ( 2 ) and the second shaft body ( 32 ) is equipped with a second slot ( 21 ) for engaging and positioning with the second wing part ( 325 ), and the second clip body ( 2 ) at the location corresponding to the cap ( 33 ) is further equipped with a second pressing piece ( 22 ). 
     
     
         4 . The automatic pop-open hair clip according to  claim 3 , wherein at the ends of the first slot ( 11 ) distant from the first shaft body ( 31 ), a first positioning block ( 13 ) is provided for engaging and positioning the first wing part ( 314 ); at the ends of the second slot ( 21 ) distant from the second shaft body ( 32 ), a second positioning block ( 23 ) is provided for engaging and positioning the second wing part ( 325 ). 
     
     
         5 . The automatic pop-open hair clip according to  claim 4 , wherein the resilient telescopic torsion element ( 34 ) at its engagements with the first coupling groove ( 3241 ) and the second coupling groove ( 334 ) is provided with a torsion section ( 341 ), which can rotate synchronously with the respective first coupling groove ( 3241 ) and the second coupling groove ( 332 ).
