Patent ID: 7448293

Claim:
A control system for driving a motor to perform a plurality of actions, comprising: a motor gear set having a first operating mode and a second operating mode; a first switch gear set matched with the motor gear set, wherein the first switch gear set produces a first switch mode and a second switch mode via the first operating mode and the second operating mode, respectively; a first action gear set matched with the first switch gear set for rotation, wherein the first action gear set produces a raising mode and a downward pressing mode via the first operating mode of the motor gear set and the first switch mode of the first switch gear set, respectively; a second switch gear set matched with the first switch gear set, wherein when the first action gear set is in the raising mode, the second switch gear set produces a third switch mode via the second switch mode of the first switch gear set, and when the first action gear set is in the downward pressing mode, the second switch gear set produces a fourth switch mode via the second switch mode of the first switch gear set; a second action gear set matched with the second switch gear set, wherein the second action gear set produces a rotation mode via the third switch mode of the second switch gear set; and a third action gear set matched with the second switch gear set, wherein the third action gear set produces a rotation mode via the fourth switch mode of the second switch gear set.
