Since some die-casting products have no clamping parts on their bodies, the only option is to clamp the material handle to achieve product removal. The special clamp for clamping the material handle is called a material handle removal clamp. However, the current material handle removal clamp can only contact with the two sides of the die-casting when removing the parts, so as to achieve the removal and clamping of the die-casting. This clamping method has the problem of the die-casting falling off the clamp when subjected to external force during the removal process. In view of this, the utility model is proposed to provide a clamp claw for clamping the material handle of the die-casting to solve the above problem. Utility Model Content
