Paper folding device for opening window on notebook

Abstract

The invention relates to a paper folding device for opening a window on a notebook. The paper folding device is characterized by comprising a base; a positioning cavity is formed in the base; and an extension base is arranged in the positioning cavity. The paper folding device further comprises a driving mechanism for driving the extension base to extend out of and shrink back from the positioning cavity, wherein the extension base includes an inner base and an outer base arranged in a split manner; the outer base is positioned on the outer side of the inner base; a paper folding flange is arranged at the outer side end of the outer base; a pushing mechanism for pushing the outer base to outwards expand when extending the extension base out of the positioning cavity is arranged between the inner base and the outer base; and a return mechanism for pushing the outer base to inwards return when shrinking the extension base from the positioning cavity is arranged between the outer base and the inner wall of the positioning cavity. The paper folding device for opening the window on the notebook, provided by the invention, can automatically fold a paper on a window opening inner side, and is high in working efficiency and excellent in paper folding effect; and the paper is not easy to damage.

Description

Technical field [0001] The invention relates to a paper folding device, in particular to a paper folding device used for opening windows on notebooks. Background technique [0002] Such as figure 1 As shown, the notebook with open windows includes a notebook body 1', and a window 11' is provided on the front side of the notebook body 1'. In order to prevent scratches on the notebook, it is necessary to wrap paper on the notebook body. At the time, first wrap the paper on the front side of the notebook body, and then fold the paper toward the inside of the window at the opening position. At present, the paper folding operation at the 11' position of the window is done manually, which is low in efficiency and , The effect of origami is poor, and the paper is easily damaged. Summary of the invention [0003] The purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a paper folding device for opening windows on notebooks, ...
