The angle measuring plate 2 is arranged on the shell 1 and is used for measuring the value of the included angle between the two ruler strips 4. The reference structure is composed of two positioning columns 3 which are arranged in parallel, two ends of each positioning column 3 are connected with the shell wall of the shell 1, and the two positioning columns 3 are separated by a certain distance to form an initial gap 301. The shell 1 is provided with a ruler outlet 101, one end of the ruler strip 4 is connected with the ruler spring structure 5, the other end of the ruler strip penetrates through the initial gap 301 and then stretches out from the ruler outlet 101, and the angle measuring plate 2 is located above the ruler outlet 101.

In the following, the cantilever part 6 is taken as an example, and as shown in fig. 6, the cantilever part 6 has a first measuring point C and a second measuring point D, but the cantilever part 6 has an irregular shape, so that the conventional tape measure cannot be used for straight line measurement. The position O is the measurement zero point of the tape measure of the present utility model, and the position where the initial slit 301 is located is the position O. At this time, one of the tapes 4 is pulled out and abutted against the first measuring point C, so as to obtain a distance L1 between the first measuring point C and the position O. And simultaneously, the other ruler strip 4 is drawn out and is abutted to the second measuring point D, so that the distance between the second measuring point D and the position O is L2. At this time, the throughput corner plate 2 reads the value of the included angle between the two strips 4 as a.
