SCISSORS

WIPO Patent Application WO/2017/020871

A1

A pair of scissors, comprising two blade bodies (1 and 2) and a fastening connector component. The fastening connector component comprises a threaded bolt (3), a fastening nut (4), a rotation-stopping sleeve (5), a flexible cushion element (7), and a rotation-stopping sleeve limiting element (6). Provided on the wall of a rotation-stopping hole (9) and/or the rotation-stopping sleeve is an extraction structure (12) for extracting the rotation-stopping sleeve mounted on the exterior of the fastening nut of the threaded bolt and within the rotation-stopping hole. An outer threaded part (21) of the threaded bolt runs through a through hole on the two blade bodies and the cushion element to be connected with the fastening nut. The threaded bolt and the fastening nut rotatably mount the two blade bodies together. A first rotation-stopping part (11) fits a second roatation-stopping part (13) to restrain rotation of the fastening nut relative to the rotation-stopping sleeve. A third rotation-stopping part (17) fits a fourth rotation-stopping part (25) to restrain rotation of the rotation-stopping sleeve relative to the threaded rod. The threaded rod and the fastening nut are non-rotatably mounted together. The fastening nut does not rotate in reverse and come loose relative to the threaded rod, thus allowing the moving blade body and the static blade body to remain at the set optimal position, and allowing the rotation-stopping sleeve to be extracted conveniently, quickly, and reliably from the rotation-stopping hole.
