Hair clip with a ring spring

Abstract

A hair clip including a left clamping portion, a right clamping portion, a positioning pin, and a ring spring. The internal side of the left and right clamping portions is provided with a pair of projecting ears near the center of the upper portion for a pivotal connection. The projecting ears include pin holes for the insertion of the positioning pin. A groove is formed slightly above the projecting ears of the left and right clamping portions, respectively, such that the ring spring is positioned against the external side of the grooves when the ring spring is forced in an open position. In this way, a resilient force created by the ring spring may act upon both of the left and right clamping portions, thereby forming a proper inward clamping force.

What is claimed is: 
     
         1 . A hair clip, comprising a left clamping portion, a right clamping portion, a positioning pin, and a ring spring, the internal side of the left and right clamping portions being provided with a pair of projecting ears near the center of the upper portion for a pivotal connection, the projecting ears having pin holes for the insertion of the positioning pin,
 wherein a groove is formed slightly above the projecting ears of the left and right clamping portions, respectively, such that the ring spring is positioned against the external side of the grooves when the ring spring is forced in an open position,   whereby a resilient force created by the ring spring may act upon both of the left and right clamping portions, thereby forming a proper inward clamping force.   
     
     
         2 . The hair clip of  claim 1 , wherein the ring spring is bent in a polygonal shape.
