Abstract: A firing control system with multiple safeties is disclosed. It comprises a base, a return spring, a firing pin releaser, and a trigger connecting bar. The trigger connecting bar is connected with the trigger of the pistol and has a firing safety portion with a T shape. The design of the firing safety portion with a limit protrusion portion of the firing pin releaser of the present invention form a safety mechanism for unintentional discharge of the pistol, which improves the problem that the existing improved products are easy to cause the pistol to fire under an unfired state.

Abstract: An energy-saving hydraulic system includes an exerting hydraulic device, a buffering receptacle arranged at one side of the exerting hydraulic device, an impetus hydraulic device connecting to the exerting hydraulic device, and a recovering hydraulic device. The exerting hydraulic device has a loading receptacle selectively disposed at a first high position and a first low position. The impetus hydraulic device has a transferring receptacle selectively disposed at a second high position, a recovering position, and a second low position. The second low position is lower than the buffering receptacle. The recovering hydraulic device connects the exerting hydraulic device and the impetus hydraulic device, and includes a sustaining portion. When the impetus hydraulic device is lowering to the second low position, it contacts the sustaining portion of the recovering hydraulic device to push working liquid to flow back the exerting hydraulic device from the recovering hydraulic device.
