The supporting device includes a bidirectional drive motor 3 fixedly installed on the middle inner side of the inclinometer body 1, a threaded rod 4 fixedly connected to the output end of the bidirectional drive motor 3, two threaded blocks 5 threadedly connected to the outer side of the threaded rod 4, a connecting rod 6 rotatably sleeved on the lower side of the threaded block 5, an industrial suction cup 7 rotatably sleeved on the lower side of the connecting rod 6, and an air pump 9 connected to one side of the industrial suction cup 7.

[0025] Among them, the counterweight assembly includes a hook 18 fixedly connected to the front end surface of the lower side of the pointer 14 and a counterweight block 15 sleeved on the outside of the hook 18. The surface of the dial 12 is provided with a plurality of grooves 13 matched with the rotating roller 16. The plurality of grooves 13 are arranged equidistantly below the inner scale line of the dial 12. Four rollers 2 are bolted to the lower side of the inclinometer body 1. The four rollers 2 are respectively installed at the four corners of the lower side of the inclinometer body 1.

[0026] The working principle of the above embodiment is:

[0027] The inclinometer body 1 moves at a specified slope through the roller 2. During the movement, the counterweight 15 will continue to keep the pointer 14 in a vertical structure with the horizontal plane, and the back of the pointer 14 will roll in the groove 13 through the rotating roller 16 under the action of the counterweight 15. In order to better observe the slope, the two threaded blocks 5 on the outside of the threaded rod 4 can be driven by the bidirectional drive motor 3 to approach each other. The connecting rod 6 on the lower side of the threaded block 5 adjusts its own angle to move the lower side of the industrial suction cup 7 to the ground and fit it, and then the vacuum pump 9 is started to drive the connecting pipe 8 to generate suction to absorb the air in the industrial suction cup 7 to generate negative pressure and firmly adsorb it to the ground, so as to keep the inclinometer body 1 at the slope position to avoid movement. At this time, the rotating roller 16 will also roll to the corresponding position of the groove 13, and the rotating roller 16 will be stuck in the corresponding groove 13 under the elastic action of the spring 17, so that the accurate slope angle of the pointer 14 in the dial 12 can be clearly observed.
