Level gauge convenient to level

The level gauge comprises a level gauge body and a support, the support comprises a first platform, a second platform, a left pushing mechanism and a right pushing mechanism, and the first platform and the second platform are connected through a hinge joint. The left pushing mechanism and the right pushing mechanism are symmetrically arranged and fixed on the first platform, and the level gauge body is mounted at the center of the top surface of the second platform; the device further comprises a U-shaped pipe installed on the first platform, liquid is injected into the U-shaped pipe, observation balls float on the two liquid levels of the liquid, two observation holes are formed in the side face of the second platform, the observation holes are communicated with the interior of the penetrating hole, and when the second platform is horizontal, the observation balls float on the two liquid levels of the liquid. And the two observation balls can be respectively observed from the two observation holes. Leveling
