Summary:The utility model relate to technical field of a vacuum circuit-breaker, particularly an energy-storing bending arm of a vacuum circuit-breaker. One end of original bending arm is connected with a pin (1-2) directly by forge to form as a whole. Manual assembling procedures are avoided, production efficiency is improved, accuracy of pieces are guaranteed by adopting mass production by mold; at the same time, fastness and aesthetic properties of parts are improved.
