In addition, a second spring 53 is further included, one end of the second spring 53 is connected to the end of the drawing roller 51, and the other end of the second spring 53 is connected to the frame 1. The second spring 53 plays a role of returning the drawing roller 51 and also provides a reaction force. In addition, the combined pressing roller 31 is pressed down by the resistance generated by the reaction force generated by the first spring 35 and the second spring 53, and compared with the resistance provided by only using the first spring 35, the resistance is prevented from being too large because the bearing force of the first spring 35 is too large, and the first spring 35 is prevented from being too thick.

The foregoing describes the technical principles of the present invention in conjunction with specific embodiments, which are intended to illustrate the principles of the present invention and are not to be construed as limiting the scope of the present invention in any way. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
