ABSTRACT:
An improved structure for a pair of scissors with pincer-clip, especially for the control of the scissors' opening angle when it's opened, and the locking of the scissors when it's closed. This pair of scissors with pincer-clip can achieve its function by moving on one side. The limitation of its opening is achieved by a O-shape buckle that connects to the spring coils on one side and a long groove of the handle on the other side. Following the opening of the pair of scissors, the O-shape buckle moves up and down in the long groove, thus controlling the opening angle of the pair of scissors by the distance between the spring coils and the pivot, and locking the pair of scissors when it's closed.
