[0027] Embodiment 3

[0028] The difference from the first and second embodiments is that:

[0029] See also Figure 1 In the embodiment of the utility model, a positioning bolt 21 is screwed into the upper part of the slope measuring plate 2 at one side of the limit plate 5, a bolt hole 41 matching the positioning bolt 21 is provided on the upper part of the shaft body 4, and a stopper 22 is hingedly connected to the upper front side of the slope measuring plate 2 at one side of the slot 3.

[0031] Working principle: Put the horizontal plate 1 on the ground, and the flatness of the road can be known through the horizontal bubble 7. Then rotate the limit plate 5 to make it in a vertical state, and then fix the positioning bolt 21 to the bolt hole 41 on the shaft body 4 to fix the limit plate 5 in a vertical direction. Then, under the rotation of the slope measuring plate 2, the slot 3 will fit with the road. When the road has a slope, under the gravity of the counterweight block 63, the pointer 64 will always be in a vertical downward state. The corresponding data on the protractor 65 pointed by the pointer 64 is the slope value of the road.

[0032] When the ball joint 69 does not move smoothly, open the cover 68 and add lubricating oil into the oil filling cylinder 66. The lubricating oil enters the hinge groove through the oil leakage groove 67 to lubricate the ball joint 69, thereby improving the smoothness of the movement of the ball joint 69 and making the pointer 64 always in a vertical downward state;

[0033] After the measurement is completed, the positioning bolt 21 is unscrewed from the shaft body 4, and then the limit plate 5 is rotated to be received in the slot 3 on the slope measurement plate 2, and then the stop block 22 is rotated to block the upper part of the limit plate 5 to fix it.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
