Abstract

According to the ring capable of conveniently opening the express package, a rotating shaft is mounted in a mounting groove, a blade is connected with the rotating shaft through a mounting block, and power is provided for rotation of the rotating shaft through a torsional spring; the blade can be matched and installed with a middle hole formed in the rotating shaft in a penetrating mode and a limiting block installed on the inner side wall of the middle hole through a shaft pin and a protruding block arranged on the outer side face of the shaft pin, and therefore the rotating shaft can be locked through the shaft pin; according to the ring capable of conveniently opening the express package, the rotating shaft is further prevented from rotating due to the acting force of the torsional spring, so that the wearing safety of the ring capable of conveniently opening the express package is improved, the engraving grooves are formed in the outer side face of the ring body, self-defined engraving can be conducted in the engraving grooves, the ring body can be more conveniently worn and taken down through the finger grooves, and the service life of the ring is prolonged. The outer side surface of the ring body is provided with the chamfer, so that the outer side surface of the ring body is smoother.
