[0025] A posture controller 5 and an inclination sensor 6 connected therewith are arranged below the mounting base plate 1, which monitors the horizontal state of the device in real time, the posture controller 5 controls the work of the plurality of telescopic cylinders 903 at the same time, and then the plurality of vibration sensors 8 can be adjusted in angle synchronously;
