The invention relates to a spring operating mechanism and a closing latch thereof. The closing latch comprises a latch body rotatably arranged on an installation rack of an operating mechanism. The latch body is provided with an electric closing member, which can be pushed by a closing electromagnet to drive the latch body to rotate. The closing latch is separately and fixedly provided with a manual closing member, which can be pushed by a manual closing push rod to drive the latch body to rotate. When closing operation is needed, not only the closing electromagnet can push the electric closing member to drive the latch body to rotate to leave an energy storage maintaining position, but also the manual closing push rod can also push the manual closing member to drive the latch body to rotate to leave the energy storage maintaining position, that is, both manual closing and electric closing can be realized, so that even if the electric closing part has fault, normal closing can still be kept through the manual
