The contactor is an electric appliance which uses a coil to flow current to generate a magnetic field in industrial electricity so as to close a contact to control a load. The contactor is widely applied to a control circuit of a fire pump, and under the normal condition of the control circuit, after a coil of the contactor is electrified, current flowing through the coil generates a magnetic field to enable an armature to attract an iron core and drive a main contact of the contactor to be closed, and a main loop is connected. When the coil of the contactor is powered off, the current flowing through the coil disappears, the electromagnetic attraction force of the armature also disappears, and the armature is released under the action of the release spring, so that the main contact of the contactor is separated, and the main circuit is disconnected. The power for the contactor action is due to the magnetic field generated by the passage of current through the ferrous coil. Therefore, under the condition that the controller fails or the control circuit fails, the conventional contactor loses a power source for action, so that the main contact cannot act. At this time, if a fire occurs, the fire pump cannot be started, and the fire control system fails. Therefore, a mechanical emergency starting device for controlling a contactor is appeared on the market, and the mechanical emergency starting device is mainly used for starting the fire pump by a person with management authority in an emergency or other occasions requiring mechanical emergency starting of the fire pump in an emergency when a fire pump cabinet controller or a contactor secondary circuit for controlling the fire pump fails. However, the structural design of the emergency starting device of the existing emergency starting alternating-current contactor is unreasonable, the emergency starting device cannot be adapted to the alternating-current contactors of different specifications, the height of the emergency starting device cannot be matched with the height of the alternating-current contactor, the universality is poor, and the emergency starting alternating-current contactor also has the defects of complex structure, unreliable performance and inconvenient assembly.
