This die tapping wrench, when tapping, uses the second rotating handle to position the reverse positioning pin in the plug-in slot, and the forward extension rod drives the die to rotate and tap by the right-angle surface of the forward positioning pin against the die positioning slot. When it is rotated to a certain angle, the extension rod is reversely rotated, and the inclined surface of the forward positioning pin contacts the inner wall of the positioning slot and is squeezed and slides out of the positioning slot. When it reaches a suitable angle, the forward positioning pin is again plugged into the positioning slot by the tension of the spring, and the forward extension rod is rotated to continue tapping. Similarly, the forward positioning pin is positioned in the plug-in slot by the first rotating handle, and then the die can be removed from the raw material by reversely rotating the extension rod. Although this solution can achieve the purpose of tapping, it is time-consuming and labor-intensive, which limits the use of this solution.
