A driving device is adapted for use in an electric nail gun. The electric nail gun includes a supporting frame. The driving device includes a swing arm unit, a control unit and a driving unit. The swing arm unit is swingable between a standby position and a shooting position. The control unit includes a control member having a driven end portion, and an abutting end portion opposite to the driven end portion. The driving unit is for driving the driven end portion of the control member to rotate between a driving position and a non-driving position, and includes a control-member biasing resilient member disposed between the driven end portion of the control member and the supporting frame.

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; anda 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; andwherein 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. 2. The driving device as claimed in claim 1, wherein said control member is pivotally mounted to the supporting frame at a portion of said control member which is disposed between said driven end portion and said abutting end portion. 3. The driving device as claimed in claim 2, wherein said control unit further includes a pivot pin connecting rotatably said control member to the supporting frame. 4. The driving device as claimed in claim 3, wherein: said swing arm unit includes a swing arm and a rod member;said swing arm has a pivot end pivotally connected to the supporting frame, and a swinging end;said rod member is fixedly received within said swinging end of said swing arm, and is formed with said abutment surface; andsaid abutting end portion of said control member has an abutting surface abutting against said abutment surface of said rod member such that, when said driven end portion of said control member is at the driving position, an angle is formed between an extending line of said abutting surface and a straight connecting line which extends through centers of said rod member of said swing arm unit and said pivot pin of said control unit. 5. The driving device as claimed in claim 4, wherein said swing arm unit further includes a swing-arm biasing resilient member disposed between the supporting frame and said swing arm for biasing said swing arm unit toward the standby position. 6. The driving device as claimed in claim 4, wherein the angle is ranged between 85 to 95 degrees. 7. The driving device as claimed in claim 6, wherein the angle is ranged between 88 to 92 degrees. 8. The driving device as claimed in claim 4, wherein said control member further has a connecting portion connected between said abutting end portion and the portion of said control member which is disposed between said driven end portion and said abutting end portion, and being not parallel to the extending line of said abutting surface of said abutting end portion. 9. The driving device as claimed in claim 1, wherein said driving unit is a solenoid valve.
