The invention relates to a stress sensor fixing clamp of a fiber bragg grating, and belongs to the technical field of steel wire stress detection. Comprising a clamping piece, an upper groove is formed in the top of the clamping piece, a steel pipe is arranged on the upper groove, and a stress sensor is arranged in the steel pipe; the clamping piece is arranged in the hoop and is connected with the hoop in a clamping manner; a lower groove is formed in the bottom of the clamping piece, a wire penetrating cavity is defined by the lower groove and the bottom of the hoop, and a steel wire penetrates through the wire penetrating cavity. Side grooves are symmetrically formed in the two sides of the clamping piece, and the two side faces of the hoop are clamped in the corresponding side grooves. The hoop is a U-shaped structural member. Supporting legs are symmetrically arranged at the top of the hoop, hoop screw holes are symmetrically formed in the two supporting legs, and screws are arranged in the hoop screw ho
