The working principle of the utility model is as follows:

initially, the book supporting plate 2 is in a folded state, completely hidden in the groove 11 and supported by the small convex column 13, the sealing plate 41 or/and the supporting plate 43, the back surface of the book supporting plate 2 faces upward and is coplanar with the tabletop 1, the sliding block 45 is at a rear dead point position, the sealing plate 41 naturally droops under the constraint of the inclined supporting block 42, a certain gap is formed between the sealing plate and the buffer spring on the limiting block 14, and the elastic supporting piece 46 is separated from the support 12.

When the book support frame needs to be opened, the rear end of the back surface of the book support plate 2 is lightly pressed by a hand to enable the book support plate 2 to rotate around the small convex column 13, while the rear end of the book support plate 2 swings downwards, the sealing plate 41 swings forwards (the swing amplitude is limited by the limit block 14) around the hinge point of the front end of the sealing plate, the front end of the book support plate 2 tilts, then the thumb extends into the through groove between the two cushion blocks 21 of the book support plate 2, the book support plate 2 is held to pull forwards along the trend, the sealing plate 41 swings backwards, along with the gradual forward movement and the rising of the book support plate 2, the bottom support strip 461 at the bottom end of the elastic support piece 46 contacts the bottom stop block 122 firstly, then the elastic support piece 46 gradually generates bending elastic deformation forwards, the bottom support strip 461 at the lower end of the elastic support piece 46 slides upwards at the front end of the bottom stop block 122 in a blocking manner, when the bottom support strip 461 slides to the blocking critical point of the bottom stop block 122, the slider is at a front dead point, meanwhile, the bottom supporting bars 461 start to move backwards under the elastic force of the elastic supporting pieces 46 until the bottom supporting bars 461 abut against the included angle between the support 12 and the bottom stop 122, the limiting piles 121 are sleeved at the lower ends of the elastic supporting pieces 46, and when the bottom supporting bars 461 slide to the blocking critical point of the bottom stop 122, the sealing plate 41 swings and rises to the highest position, the sealing plate 41 just covers the groove 11, the upper surface of the sealing plate 41 is flush with the upper surface of the table top 1, and then the sealing plate 41 is supported and stabilized by the elastic supporting pieces 46 at the left side and the right side; and finally, the book supporting plate 2 is turned backwards to enable the book supporting plate 2 to be completely opened, the front face of the book supporting plate 2 forms an obtuse angle with the desktop 1, and the book supporting plate 2 is supported by the inclined supporting block 42, so that not only is the book supporting plate 2 not to exceed the vertical plane (shown in figure 2) where the rear end face of the desktop 1 is located, but also the highest point of a book does not exceed the vertical plane where the rear end face of the desktop 1 is located after the book is supported, and the influence on the free movement of front-row students is avoided. In the above process, the limiting pile 121 plays a role in protecting, and prevents the bottom support bar 461 from moving upwards excessively to cause extrusion between the front end face of the sealing plate 41 and the front groove wall of the groove 11.

After the book supporting plate 2 is opened, a book is placed on the supporting plate 43, the spine of the book is positioned in the through groove between the two cushion blocks 21, the left half part and the right half part of the book are respectively clamped by the book clamps 3 attracted to the corresponding sides of the cushion blocks 22, and at the moment, the book can be read. Or the top end of the book is abutted against the vertical front end face of the cover plate 452, the bottom end of the book is aligned with the front indication line 15 on the desktop 1, then the book holder 3 is taken down according to the method for taking down the book holder, the front end of the book holder 3 is aligned with the rear indication line 15 on the desktop 1, then the book is clamped, and finally the book and the book holder 3 are moved onto the book supporting plate 2 according to the method for placing the book holder. When a note is needed, the book and the book holder 3 are taken off together from the book supporting plate 2 by the above-mentioned method for taking off the book holder, and then the book is placed on the desktop 1 for taking a note on the book, and of course, the right book holder 3 can be removed for taking a note again when necessary. After the notes are taken, the books and the book clamps 3 are quickly placed on the book supporting plate 2 together according to the method for placing the book clamps.

When the tablet computer is required to be used for learning, the book end 3 is firstly taken down from the cushion block 21, the magnetic force of the magnet is utilized to be placed on the inclined supporting block 42, then the two rotating supporting plates 431 are opened to be perpendicular to the supporting plate 43, at the moment, the two rotating supporting plates 431 can be used for supporting the bottom of the tablet computer together, and the tablet computer leans against the book supporting plate 2. Due to the fact that the books are placed on the book supporting frame in good smoothness, when the tablet personal computer is used, the books do not need to be taken down, and the tablet personal computer can be directly leaned on the books after the rotary supporting plate is screwed out through the handle below the supporting plate.
