Fix the right leg 31 at the starting point of the slope to be measured, pull the left leg 21 to move the left leg 21 along the slope, and the left leg 21 will pull the inner rod 2 out of the outer rod 3 . And along with the left supporting foot 21 moves on the slope, the upper end of the left supporting foot 21 and the upper end of the right supporting foot 31 can produce height difference, make ruler rod 1 produce inclination.

The spherical wheel 211 makes the sliding of the left supporting foot 21 smoother, so that the left supporting foot 21 can move along the slope better.

After the ruler bar 1 is tilted, the right leg 31 will rotate around the hinge, and a certain angle will be generated between the fixed plate 33 so that the right leg 31 can remain perpendicular to the ruler bar 1 . The lower surface of the fixed plate 33 is fully in contact with the ground, so that the slope gauge can not be turned over due to the inclination of the right supporting foot 31. The friction pad 34 can increase the friction between the fixed plate 33 and the ground, so that there will be no slipping between the fixed plate 33 and the ground, and the stability of the gradient scale can be increased.
