The present invention relates to a quick coupler and, more specifically, to a quick coupler, capable of improving rigidity and durability through an optimal composition and structural deformation which is different from an existing invention, and improving solidity and rigidity by being integrally formed in a casting method in which various components are assembled without welding. The quick coupler includes: an upper body including a connection hole arranged at intervals by being connected to the front end of an excavator by a hinge; and a lower body integrally connected to the lower side of the upper body and including a connection groove for connecting a working machine to one side. The upper body and the lower body are integrally connected by a reinforcing connection unit inclined in a diagonal direction. The upper body, the reinforcing connection unit, and the lower body are integrally formed in the casting method. |
