Connecting structure of LVDT (Linear Variable Differential Transformer) displacement sensor

The utility model relates to the field of power plants. The utility model discloses an LVDT (Linear Variable Differential Transformer) displacement sensor connecting structure, which comprises a first connecting piece connected with a mandrel connecting rod of an LVDT displacement sensor, and a second connecting piece connected with a mandrel connecting rod of the LVDT displacement sensor, the second connecting piece is used for connecting a piece to be tested; the first connecting piece and the second connecting piece are connected through the movable piece, and the movable piece can move relative to the radial direction of the mandrel connecting rod. According to the utility model, when the valve rod deviates, the radial displacement of the movable part along the mandrel connecting rod can reduce the force acting on the mandrel connecting rod due to the deviation of the valve rod, so that the mandrel connecting rod is prevented from being snapped, the accuracy of feedback information of the sensor is improv
