1. A driving device adapted for use in an electric nail gun, the electric nail gun including a supporting frame, a rotatable flywheel that is pivotally mounted to the supporting frame, and an impact member, said driving device comprising:
a swing arm unit pivotally mounted to the supporting frame, including an abutment surface, adapted to permit the impact member to be movably mounted thereto, and swingable between a standby position and a shooting position such that, when said swing arm unit is at the standby position, the impact member is spaced apart from the flywheel, and when said swing arm unit is at the shooting position, the impact member is in contact with the flywheel; a control unit including a control member that has a driven end portion, and an abutting end portion opposite to said driven end portion and slidably abutting against said abutment surface of said swing arm unit; and a driving unit for driving said driven end portion of said control member to rotate between a driving position and a non-driving position such that, when said driven end portion of said control member is at the driving position, said swing arm unit is at the shooting position, and when said driven end portion of said control member is at the non-driving position, said swing arm unit is at the standby position; wherein said driving unit includes a main body, and a valve rod movable relative to said main body for rotating said driven end portion of said control member between the driving position and the non-driving position; and wherein said driving unit further includes a control-member biasing resilient member disposed between said driven end portion of said control member and the supporting frame, for providing a resilient force to push said driven end portion of said control member to abut against said valve rod so as to maintain said driven end portion of said control member at the non-driving position. |
