Special detection device for inclination of refueling bolt

The invention provides a special detection device for inclination of a refueling bolt, and relates to the technical field of refueling bolt detection.The detection device comprises a positioning supporting frame used for being installed on a refueling bolt well body, and a measuring scale is rotationally arranged in the middle of the side, facing the refueling bolt well body, of the positioning supporting frame; the measuring scale is parallel to the plane where a well mouth in the refueling bolt well body is located, and the rotating plane of the measuring scale is perpendicular to the refueling bolt well body. A positioning block is arranged on one side, facing the refueling bolt well body, of the measuring scale in a sliding mode, the sliding direction of the positioning block is consistent with the extending direction of the measuring scale, the positioning block is provided with a positioning center column, and the axis direction of the positioning center column coincides with the rotating center of the
