The present invention relates to a device for measuring the rotation angle of a blade comprising a main body (20), a fixing device (60), and a mount (80). A housing (22) forms the appearance of the main body (20), and a potential meter (52) is installed in a frame (26) inside the housing (22). An interlocking hole (32) rotated with a potential rotating shaft (54) of the potential meter (52) is installed in the frame (26). The interlocking hole (32) is rotated with a mount (80). A rotation center shaft (40) is installed to be exposed to the lower part of the housing (22) by being penetrated into the center of the interlocking hole (32), and the rotation center shaft (40) is mounted on a central axis hole (86) equipped in the rotation center of the mount (80). A coupling pin hole (88), into which a coupling pin (46) equipped in the main body (20) is inserted, is formed in the upper side of the mount (80), and a mount handle (90) is equipped to operate the mount (80). The angle change value is detected by using the voltage change amount measured in the potential meter (52), and indicated in a display. According to the present invention, the rotation angle of a blade (18) can be easily measured. |
