The invention discloses an energy saving lever mechanism. The mechanism comprises a supporting point, a power arm is arranged on one side of the supporting point, a resisting arm is arranged on the other side of the supporting point, the power arm is provided with an energy storage mechanism, the free end of the power arm is used for exerting force to the upper side of the free end, and the free end of the resisting arm is used for obtaining force. Operation driving force and limit free of use space are reduced, and the problems that a traditional mechanism wastes labor, and use space is limited are solved.
