Vacuum circuit breaker with novel transmission structure

The invention belongs to the technical field of vacuum circuit breakers and particularly relates to a vacuum circuit breaker with a novel transmission structure. The breaker comprises a shell, arc extinguishing boxes and a motion mechanism, wherein the arc extinguishing boxes which are uniformly arranged are fixedly connected with the inner wall of the shell in the cavity of the shell, the numberof the arc extinguishing boxes is three, a first wire is fixedly connected with an upper part of each arc extinguishing box, first wires are electrically connected with a machine, each arc extinguishing box is internally and fixedly connected with a static contact, the static contact is communicated with the first wire, a moving contact is slidably connected with the position, below each static contact, in the arc extinguishing box, and a movement mechanism is arranged on the right side of each first wire. The breaker is mainly used for solving problems that an existing circuit breaker needs the opening time in the op
