Abstract:
1. A clutch transmission mechanism of a printing device for transmitting a driving force of said printing device to a transmission gear module of said printing device, said clutch transmission mechanism comprising: a power input shaft; a power input gear sheathed around and fixed on said power input shaft; a gear-shifting arm comprising a movable shaft collar and a sustaining part, wherein said movable shaft collar is sheathed around said power input shaft, and movable along said power input shaft; a first gear-shifting module comprising: a second gear-shifting module comprising: wherein when said movable shaft collar of said gear-shifting arm is rotated by a first angle and a first pushing force greater than said first elastic force is applied on said movable shaft collar, said sustaining part pushes said first clutch gear to cause engagement between said second claw part of said first clutch gear and said first claw part of said first connecting gear and engagement between said first clutch gear and said transmission gear module, so that said transmission gear module is driven to operate in a first gear-shifting mode, wherein when said movable shaft collar of said gear-shifting arm is rotated by a second angle and a second pushing force greater than said second elastic force is applied on said movable shaft collar, said sustaining part pushes said second clutch gear to cause engagement between said fourth claw part of said second clutch gear and said third claw part of said second connecting gear and engagement between said second clutch gear and said transmission gear module, so that said transmission gear module is driven to operate in a second gear-shifting mode.
