    Abstract: Aiming at the defect existing in the traditional circuit breaker contact-linked shaft structure, this paper designed a new kind of shaft structure. This paper introduced the existing structure, gave the working principle of new shaft structure and analyzed the strength of new shaft structure. The comparison of the two structure’s strength, reliability, usability and mechanical life verifies that the new structure is easy to assemble reliably, which overcomes the defects including the complex processing technique, rivetingdeformation and working loose of traditional shaft structure, raises the mechanical life of products and verifies the reliability of this shaft.
    Key words: operating mechanism shaft; mechanical life; reliability
