A rotating ring 6 is fixedly sleeved on the outer side of the threaded sleeve 4, and a connecting rod 7 is fixedly connected to the top of the threaded rod 5. A protractor 8 is fixedly connected to one side of the connecting rod 7, and a rotating shaft 9 is rotatably connected at the center of the protractor 8. A pointer 10 is fixedly sleeved on the outer side of the rotating shaft 9, and a card slot is opened on one side of the base 1;

[0033] See also Figure 1 and Figure 4 , an auxiliary component is provided on the outside of the threaded rod 5, including a pull ring, which is fixedly connected to the top of the connecting rod 7, the threaded sleeve 4 is movably connected to the movable frame 3 through a bearing, and the rotating rod 2 is movably connected to the base 1 through a bearing, which can make the connecting rod 7 and the threaded sleeve 4 more stable when rotating, thereby extending the life of the device;

[0034] See also Figure 1 , Figure 2 and Figure 4 , both the front and rear sides of the movable frame 3 are provided with limiting grooves, and limiting blocks 11 are embedded in the two limiting grooves. The two limiting blocks 11 are fixedly connected to the front and rear sides of the threaded rod 5 respectively. Two positioning grooves are provided on the front side of the movable frame 3, and a spring 12 is fixedly connected to the front side of the base 1. A handle 14 is fixedly connected to the front side of the spring 12. A latch 15 is fixedly embedded in the handle 14. The two limiting grooves cooperate with the two limiting blocks 11 to limit the threaded rod 5, so that the threaded rod 5 can drive the connecting rod 7 to move up and down more stably;

[0035] See also Figure 1 and Figure 4The rear side of the latch 15 passes through the spring 12 and extends to one of the positioning grooves. Guide plates 16 are fixedly connected to both sides of the handle 14. The two guide plates 16 are symmetrically arranged with the center line of the handle 14 as the axis.

When the latch 15 is away from one of the positioning grooves, the pull ring can be held again to rotate the movable frame 3 upward by ninety degrees. After it is in a vertical state, the handle can be released again, and the spring 12 will rebound without being stressed, and the latch 15 can be driven by the handle to move backward and extend to the other positioning groove to position the movable frame 3. Then, according to the current use environment, the base 1 can be fixed by placing the foot in the groove, and then the threaded sleeve 4 can be rotated. Because the limit blocks 11 on both sides of the threaded rod 5 are matched with the two limit grooves respectively, the threaded rod 5 can drive the connecting rod 7 to move vertically up and down, and the connecting rod 7 drives the protractor 8, the rotating shaft 9 and the pointer 10 to move;

[0037] Through the above structure, the height of the device can be adjusted according to the needs of the surveyor, and the problem of the existing highway slope measuring device, which has a complex structure and poor portability, resulting in inconvenient use, poor flexibility and practicality, is solved.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
