The present application discloses a blade mechanism and an electric scissors having the blade mechanism. The blade mechanism includes a setting blade, a moving blade, and a rotating shaft assembly. The rotating shaft assembly respectively passes through the setting blade and the moving blade to allow the setting blade and the moving blade being rotatablely connected. The cutting edge of the moving blade is automatically ground when the moving blade frictionally rotates relative to the setting blade. According to the present application, the moving blade and the setting blade of the blade mechanism open or close to generate friction, allowing the cutting edge of the moving blade to be automatically ground by the setting blade, thus the durability of the moving blade is improved.

A pair of scissors for opening a box includes a first cutting member and a second cutting member. The first cutting member is provided with a first handle on an end thereof, and the second cutting member is provided with a second handle on an end thereof. The scissors further include a connecting nail and a movable hole defined on the first cutting member. The movable hole is arranged for the connecting nail to move, and the connecting nail passes through the movable hole and is connected with the second cutting member, so that the first cutting member pivots around the second cutting member by the connecting nail. The connecting nail is movable in the movable hole which allows the first cutting member to move relatively to the second cutting member. The scissors have the advantages of simple structure, low cost and convenient operation.
