Claims

[Scope of utility model registration request]

A variable blade for construction machinery in which a main blade and a sub-blade arranged in front of the main blade are connected by a hydraulic cylinder for extending and retracting the blade on the same side. It has a wing edge, a longitudinally long side edge that is in contact with the end surface of the wing edge, and an end bit that is overlapped with the wing edge and a part of the side edge and is fixedly installed so as to protrude from the extreme end. A variable blade for a construction machine, characterized in that the side edge is formed so that the bolt hole position and outer shape are vertically and horizontally symmetrical from the center line.
