    摘要: A tape measure frame assembly is provided for installation within the handle of a hand tool. The assembly includes a gearing connection between the tape and a retracting spring, which enables the assembly to be elongated in conformity with the tool handle. When the hand tool is used, the tape measure is always present when needed.
