Multi-arm vertical inclination measuring mechanism

The utility model discloses a multi-arm vertical inclinometry mechanism, which is used for vertically detecting the inclination degree of a plane to be detected and comprises a detection device used for detecting an inclination angle generated after the plane to be detected inclines. The sensing device is connected with the side wall of the detection device, and the sensing device is used for sensing the stress when the plane to be detected inclines. And the counterweight device is connected with the detection device. The sensing device senses the stress direction and size of a to-be-detected plane through the output quantity, the counterweight device reflects the inclination angle of the to-be-detected plane through the included angle between the counterweight device and the direction of the output quantity of the sensing device, and the detection device inclines according to the included angle between the sensing device and the counterweight device and directly shows the inclination degree of the to-be-dete
