Abstract

The utility model provides a nearsightedness-proof book clamp for the technical field of stationery. The utility model is characterized in that the nearsightedness-proof book clamp is provided with an upper and a lower clamp sheets which are movably connected through a rotary shaft which is provided with a torsional spring of which the head and the tail ends are respectively used for topping the upper and the lower clamp sheets, the lower clamp sheet is provided with two supporting legs and the middle of the lower clamp sheet is provided with an opening. Because the utility model adopts the technical scheme, an elevation angle formed between a book surface and a tabletop forms the optimal reading visual angle for achieving the purpose of preventing nearsightedness. Both hands can also be released for easily taking notes. Books can not be damaged regardless of the time of clamping. The nearsightedness-proof book clamp has the advantages of convenient use and no damage of the books, and can also be used for preventing the nearsightedness.

Description

The myopia prevention book clamp

Technical field

The utility model belongs to the stationery technical field, is specifically related to a kind of myopia prevention book clamp.

Background technology

People study take notes or the reader when reading books, need lie on the desk by books or books with hand rest, just can carry out, like this, it is very inconvenient to use, moreover of a specified duration, because the page and the eyes visual angle of books are not good, the reader can feel eye fatigue, causes myopia easily, also fragile books.

Summary of the invention

The purpose of this utility model is a kind of easy to use, myopia prevention book clamp that can not damage books of design.

The technical scheme that the utility model is taked is to have upper and lower intermediate plate, and upper and lower intermediate plate flexibly connects by rotating shaft, and rotating shaft is provided with torsion spring, and torsion spring head, end head on upper and lower intermediate plate respectively, are provided with two supporting legs on lower clamping piece, is provided with opening in the middle of it.

Because the utility model has been taked technique scheme, during reading, books are opened, opening book clamp clamps books from top, opening portion is just crossed spine, clamp the left and right sides of spine, like this, neither can damage spine for a long time, also can not cause the written written distortion after opening and influence reading because of reading a book, the more important thing is, because the support of two legs of book clamp not only makes the position of the following end in contact desktop of book form the firm situation of 3 one sides with two legs of book clamp, and make written and acclivitous slightly elevation angle of desktop formation, make the people when reading, reach an optimal viewing angle, thereby can alleviate the visual fatigue that caused for a long time because of reading a book; If when reading takes notes while seeing, use this book clamp just can remove left hand from by book, the trouble that the right hand is write can be avoided the fatigue of the health that causes by book because of two hands; No matter see which page or leaf, book clamp can keep duty always during people's rest, is placed on the desk and letter submitted to one's superior is opened shape, removes the trouble of turning over book when continuing to read again from, does not worry pressing from both sides book and crosses for a long time and the damage books; Both made when not reading a book, the handicraft that also this book clamp can be used as a fineness is positioned over to be received on the table, because it seems to resemble a model aircraft of spreading its wings to fly.The utility model makes the elevation angle that forms between written and desktop, constitutes best reading visual angle, reaches the purpose of pre-myopia prevention; Both hands can also be freed, can do notes very easily; How long no matter press from both sides, book can not damaged.
