Bushing used for electric brace rod

The invention discloses a bushing used for an electric brace rod. The bushing comprises a main bushing body which is tubular overall, wherein a plurality of strip-shaped grooves parallel to the axis direction of the main bushing body are formed in the outer peripheral surface of the main bushing body at intervals in the circumferential direction, a first end of the main bushing body is an open end, the tail end positions, located at the first end, of strip-shaped grooves are closed to form first elastic structure, a positioning ring is arranged on the inner peripheral surface of a second end of the main bushing body, the tail end positions, located at the second end, of strip-shaped grooves are of through groove structures, the positioning ring comprises a plurality of arc-shaped sections,the adjacent arc-shaped sections are connected through second elastic structures, and the plurality of arc-shaped sections are fixedly connected with the inner peripheral surface of the second end ofthe main bushing body. 本发
