[0022] The utility model provides a tool for measuring a space angle, comprising a plane right-angle measuring ruler 1 and an indicating rod 2, wherein a rotation axis 7 is arranged at the center of the plane right-angle measuring ruler 1, one end of the indicating rod 2 is connected to the rotation axis 7, and a vertical indicating structure 3 is arranged at the other end of the indicating rod 2, the indicating rod 2 can rotate along the circumference of the plane right-angle measuring ruler 1 with the rotation axis 7 as the center, and the surface of the plane right-angle measuring ruler 1 is provided with angle indicating structures 6 distributed along the circumference thereof.

[0023] Place the plane right-angle protractor 1 vertically on the slope surface, and move the indicator rod 2 to the vertical direction to accurately measure the spatial angle.

[0024] In one embodiment, a flat plate 5 is provided on one radial side of the plane right angle ruler 1, and the plane right angle ruler 1 is vertically fixed on the surface of the flat plate 5. Figure 4 As shown, it is only necessary to place the flat plate 5 on the inclined slope to be measured to ensure that the plane right-angle ruler 1 is perpendicular to the slope surface. At this time, the indicating rod 2 is moved to the vertical direction to accurately measure the spatial angle.

[0025] The angle indicating structure 6 includes angle scale lines 61, such as Figure 1 As shown, the angle scale line 1 is marked at 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, and 90° respectively, with an accuracy of 1°.

[0026] In one embodiment, the angle indicating structure 6 further includes an angle hole 62, and the angle hole 62 is aligned with the angle scale line 61 one by one, such as Figure 1 As shown, the angle hole 62 is located on one side of the outer periphery of the angle scale line 61. The angle hole 62 can be used to construct a surface with a specified slope angle, so as to facilitate the inspection of the fixed angle of the slope surface and verify the actual slope according to the determined slope value.

[0027] In one embodiment, the interior of the indicator rod 2 is hollow, and the plane right-angle protractor 1 is inserted into the interior of the indicator rod 2 , so that the angle pointed by the indicator rod 2 can be simultaneously seen on both sides of the plane protractor 1 .
