Inclined plane angle measuring instrument

The utility model provides an inclined plane angle measuring instrument, which belongs to the technical field of measuring tools and comprises two supports, a dial plate, a fixing mechanism and a pointer. The number of the dial plates is two, the dial plates are in a semi-circular ring shape, the two dial plates are arranged on the two supports respectively and are symmetrical about the axis of the center shaft, scale lines distributed along the arc line are arranged on the dial plates, and when the two dial plates are located on the same plane, the two dial plates form a whole circular ring shape. The fixing mechanism is used for fixing the two dial plates on the same plane; the two pointers are fixedly connected and located on the same straight line, the joint of the two pointers is rotationally connected with the center shaft, and when the two dial plates form a whole ring, the connecting point of the two pointers and the center shaft is the circle center of the whole ring; and thetwo balancing weights are
