When the two vertical plates 10 are bent out, the two vertical plates 10 can be slid, and the diameter and width can be measured by the two adjacent vertical plates 10. The first bolt 5 is rotated to slide the swing plate 6, and different angles can be measured by the scale pointed to by the pointer plate 4. The instrument can measure angles, widths and diameters, and has wider practicality.

[0036] An inner groove 8 is provided on the inner top surface of the semicircular block 1, and the upper side of the swing plate 6 is slidably arranged on the inner wall of the inner groove 8.
