Inclined plane ground inclination angle tester

A slope ground inclination angle tester belongs to the technical field of technical measurement. The angle ruler is composed of an angle ruler body 1, a damping pad 2, a reading ruler 3, a positioningruler 5, a hinge shaft 7 and a ruler body 8. The goniometer 1 is riveted between the two aluminum strips 10 through rivets 9. And the reading scale 3 is arranged at an angle origin on one side of thegoniometer 1 by a hinge shaft 7, is clung to the goniometer 1 and can swing around the angle origin. The positioning ruler 5 is horizontally arranged at one end of the ruler body 8 and is perpendicular to the central axis of the ruler body 8. The damping pad 2 is clamped between the inner end face of the hexagonal head of the hinged shaft 7 and the angle ruler 1, and the reading ruler 1 is allowed to swing by hand and can stop at an adjusted position to indicate reading by means of elasticity of the damping pad 2. During angle measurement, the scale 5 is positioned to enable the scale body 8to be perpendicular to a tr
