Tape measure is one of the tools that people often use, but the current tape measure function has certain limitations and cannot meet the special needs in the application. "Double-headed tape measure" is a tape measure that can pull out equal-length scales at both ends at the same time. This special design can bring more convenience to users and has more advantages: 1. It can quickly and accurately find the midpoint of the measured object; 2. It can easily measure the scale of higher objects; 3. It can conveniently and accurately measure the internal distance of the concave space
