Protective damping instrument

The utility model relates to the technical field of automation instruments, in particular to a protective damping instrument. The device comprises a protective shell, a damping mechanism and an instrument. The damping mechanism is arranged in the protective shell, and a plurality of fixing mechanisms are arranged on the surface of the damping mechanism. The damping mechanism comprises a damping plate, a supporting column, a damping frame and a damping spring. The supporting columns are symmetrically arranged at the bottom of the damping plate, and the damping springs are arranged outside the supporting columns in a sleeving mode and located in the damping frame. The instrument is fixed on the damping plate through a fixing mechanism. When the outside of the protective shell is impacted, vibration is generated in the protective shell, and the springs are mounted outside the supporting columns, so that when the damping springs work, the instrument fixed on the damping plate can be damped and buffered through th
