The invention discloses a vibration reduction receiver supporting seat with the adjustable levelness. The vibration reduction receiver supporting seat comprises an upper flange, a supporting plate, a base, vibration reduction elements, telescopic sleeves and telescopic rods. The upper flange and the supporting plate are of disc-shaped structures. The base is of a reversely-buckled bowl-shaped structure. The vibration reduction elements are cylindrical in appearance and are wholly composed of springs, bolts and vibration reduction rubber in a vulcanization mode. The supporting plate and the base are integrally connected through the vibration reduction elements, and the three vibration reduction elements are arranged in a central symmetry mode on the plane of the upper flange. One ends of the telescopic sleeves are fixedly connected with the upper surface of the supporting plate, one ends of the telescopic rods are fixedly connected with the bottom face of the upper flange, and the telescopic rods and the telescopic sleeves are distributed in central symmetry on the respective connecting surfaces. Locking bolts penetrate through sleeve walls in the radial direction of the telescopic sleeves to lock the telescopic rods. The supporting seat has a good vibration reduction effect, the receiving precision of a receiver can be improved, the levelness degree of the supporting seat can be conveniently adjusted, and it is ensured that the receiver is in the optimal working state.
