Pull-out resistant and striking free swing-trough dummy bar head

The utility model provides a pull-out resistant and striking free swing-trough dummy bar head. An L-shaped circular hole is formed in a dummy bar head; and a fixing pin hole, which runs through the left side surface and the right side surface of the dummy bar head, penetrates through the L-shaped circular hole. Before starting, an L-shaped steel reinforcing bar is inserted into the L-shaped circular hole, a fixing pin is inserted into the fixing pin hole, and the L-shaped steel reinforcing bar, the dummy bar head and a steel blank are firmly welded together through molten steel after the molten steel is injected; and during starting, as the striking operation of a swing-trough is not needed, pull-out accidents cannot be caused during starting and the blank pulling operation can be smoothly finished during starting. The utility model has the advantages that the start-casting time is shortened, and the swing-trough is not needed in each casting operation when casting is directly started; meanwhile, the steel ca
