[0035] See also Figure 1 -4. The utility model provides a book clamping board, including a main board 1, a sub-board 2 and a support board 3. The front of the main board 1 is provided with at least one clamping board 4, the back bottom of the main board 1 is provided with a rotation hole, the sub-board 2 is provided with a first rotation axis 21 that cooperates with the rotation hole, the sub-board 2 rotates around the first rotation axis 21, the sub-board 2 is provided with an opening 22, the edge of the opening 22 is provided with a second rotation axis 23, the support board 3 rotates around the second rotation axis 23, and a positioning member is provided between the support board 3 and the main board 1;

[0036] The utility model has the following two states:

[0037] In the idle state, i.e., the first state, the support plate 3, the auxiliary plate 2, and the main plate 1 are all parallel, the support plate 3 is accommodated in the opening 22, and the auxiliary plate 2 and the main plate 1 are folded together;

[0038] When in the working state, that is, the second state, the sub-plate 2 is unfolded, and the support plate 3 is flipped toward the main plate 1. The support plate 3 and the main plate 1 are fixed by positioning parts. The main plate 1, the sub-plate 2 and the support plate 3 form a triangular support structure, so that a fixed angle is formed between the main plate 1 and the sub-plate 2, which is convenient for the main plate 1 to carry the book. The user places the book on the main plate 1 and then clamps the book with the clamping plate 4 to fix the book, which is convenient for reading and marking, providing users with good conditions for reading and marking, and cultivating good reading habits.

[0039] The utility model can quickly switch between the first state and the second state through the mutual cooperation between the main board 1, the auxiliary board 2 and the support board 3. It is simple to operate and easy to use. When in the idle state, the support board 3 and the auxiliary board 2 can be folded and gathered, which can effectively reduce the overall occupied space. The structure is simple and easy to carry.

[0040] See also Figure 5 -11, as an embodiment of the present invention, at least one buckle 11 is provided on the back of the main board 1, and the sub-board 2 is provided with a number of buckles 24 that are equal to and one-to-one corresponding to the buckles 11. When the book clamp is in an idle state, the support plate 3 and the sub-board 2 are folded and gathered toward the main board 1. After the gathering is completed, the user buckles the buckle 11 into the corresponding buckle hole 24, and the position between the sub-board 2 and the main board 1 is fixed through the snap connection between the buckle 11 and the buckle hole 24, avoiding the undesirable phenomenon of looseness or even accidental expansion between the sub-board 2 and the main board 1 in the idle state, thereby improving the overall reliability and stability. When the user needs to use the book clamp, he only needs to gently pry open the sub-board 2 to separate the buckle 11 from the buckle hole 24, thereby expanding the sub-board 2 and switching the book clamp to the working state.

[0041] As an embodiment of the present utility model, the back edge of the main board 1 is provided with an extension plate 12 extending toward the sub-board 2. The extension length of the extension plate 12 is X, and the thickness of the sub-board 2 is H, X≥H. When the book clamp is in an idle state, the sub-board 2 can be placed in a accommodating chamber composed of the main board 1 and the extension plate 12. The extension plate 12 can effectively protect the sub-board 2 to avoid unnecessary damage to the sub-board 2. At the same time, it can also prevent dust and other impurities from entering the gap between the sub-board 2 and the main board 1, causing unnecessary influence on the flipping of the sub-board 2, and improving the cleanliness of the inside of the book clamp.

[0042] As an embodiment of the present invention, a first limiter 13 is provided at the bottom back of the main board 1. The first limiter 13 limits the rotation of the sub-board 2 and limits the rotation angle of the sub-board 2 so that the angle between the main board 1 and the sub-board 2 is less than 90°, which not only meets the use requirements, but also can avoid the sub-board 2 from expanding at too large an angle during use and colliding with other devices, causing unnecessary damage to the sub-board 2 or other devices, thereby improving the safety of use. A second limiter 25 is provided at the edge of the opening 22. The second limiter 25 limits the rotation of the support plate 3 and limits the rotation angle of the support plate 3 so that the support plate 3 can only rotate toward the main board 1 and cannot rotate away from the main board 1, thereby avoiding meaningless rotation of the support plate 3. When the support plate 3 is folded and retracted, the support plate 3 can be confined between the main board 1 and the sub-board 2, thereby improving working reliability and stability.

[0043] As an embodiment of the present invention, there are two second rotating shafts 23, and the two second rotating shafts 23 are respectively located on two opposite sides of the opening 22. Both sides of the support plate 3 are provided with rotating arms 31 that cooperate with the second rotating shafts 23. By rotating the rotating arms 31 on both sides around the second rotating shafts 23, the balance of the rotation of the support plate 3 can be effectively improved, avoiding the undesirable phenomenon of deflection or twisting of the support plate 3 during the rotation process, and improving the overall stability and reliability.

[0044] As an embodiment of the present invention, the thickness of the rotating arm 31 is greater than the thickness of the sub-plate 2, and two paving grooves 14 are provided on the back of the main plate 1, and the paving grooves 14 correspond one to one with the rotating arm 31. In the first state, part of the rotating arm 31 is accommodated in the paving groove 14. Since the thickness of the sub-plate 2 and the support plate 3 are both relatively thin, in order to meet the connection strength between the support plate 3 and the sub-plate 2, the size of the rotating arm 31 set on the support plate 3 is relatively large, so that a part of the rotating arm 31 protrudes as a whole. When the book clamp is in an idle state, the protruding part of the rotating arm 31 is accommodated in the corresponding paving groove 14, so that the sub-plate 2 and the main plate 1 are tightly fitted, which can improve the matching performance between the sub-plate 2 and the main plate 1 without affecting the connection strength between the support plate 3 and the sub-plate 2.

[0045] As an embodiment of the present invention, the positioning member includes a positioning groove 15 arranged on the back of the main board 1 and a positioning protrusion 32 arranged on the support plate 3. When the sub-board 2 is unfolded, the user rotates the support plate 3 toward the main board 1, and aligns the positioning protrusion 32 on the support plate 3 with the positioning groove 15 on the main board 1, and inserts the positioning protrusion 32 into the positioning groove 15 to complete the fixation of the support plate 3 and the main board 1.

[0046] As an embodiment of the present invention, there are two positioning protrusions 32, which can improve the fixing strength between the support plate 3 and the main board 1 and improve the working stability. There are multiple positioning grooves 15, two positioning grooves 15 form a group, and multiple groups of positioning grooves 15 are evenly arranged along the length direction of the main board 1. The user can select a suitable positioning groove 15 according to specific usage requirements, and insert the positioning protrusion 32 into the positioning groove 15 to meet specific angle requirements. The angle between the main board 1 and the sub-board 2 is adjustable to meet the reading needs of different users, thereby improving the overall compatibility and practicality of use, and the adjustment operation is simple and easy to use.

[0047] As an embodiment of the present utility model, the splint 4 is arranged in the middle of the upper end of the front side of the main board 1, the length of the splint 4 is L, the width of the main board 1 is S, 0.5S≤L<S, and the use of a wider splint 4 can improve the clamping and fixing ability of the book, and at the same time can also prevent the book from being locally wrinkled during the clamping process, thereby improving the reliability of use.

[0048] As an embodiment of the present invention, a pen clip 5 is provided on the front of the main board 1. When the user is reading, if he needs to make annotations, he can immediately pick up the annotation pen placed on the pen clip 5 to make annotations. If he does not need to make annotations, he can place the annotation pen on the pen clip 5, which meets the convenience and reliability of the user's reading and enables the reader to develop a good habit of marking at will.

[0049] In summary, the utility model provides a book clamp, which can quickly switch between a first state and a second state through the mutual cooperation between the main board 1, the sub-board 2 and the support board 3. It is simple to operate and easy to use. When in the idle state, the support board 3 and the sub-board 2 can be folded and gathered, which can effectively reduce the overall occupied space. The structure is simple and easy to carry. The position of the sub-board 2 and the main board 1 is fixed by the snap connection between the buckle 11 and the snap hole 24, which avoids the undesirable phenomenon of looseness or even accidental unfolding between the sub-board 2 and the main board 1 in the idle state, thereby improving the overall reliability and stability. The extension plate 12 can effectively protect the sub-board 2 and avoid unnecessary damage to the sub-board 2. At the same time, it can also prevent dust and other impurities from entering the gap between the sub-board 2 and the main board 1, causing unnecessary influence on the flipping of the sub-board 2, and improving the internal stability of the book clamp. Cleaning; By rotating the rotating arms 31 on both sides around the second rotating axis 23, the balance of the rotation of the support plate 3 can be effectively improved, and the undesirable phenomenon of deflection or twisting of the support plate 3 during rotation can be avoided, thereby improving the overall stability and reliability; when the book clamp is in an idle state, the protruding part of the rotating arm 31 is accommodated in the corresponding give way groove 14, so that the sub-plate 2 and the main plate 1 fit tightly together, and the matching performance between the sub-plate 2 and the main plate 1 can be improved without affecting the connection strength between the support plate 3 and the sub-plate 2; the user can select a suitable positioning groove 15 according to specific usage requirements, and insert the positioning protrusion 32 into the positioning groove 15 to meet the specific angle requirements. The angle between the main plate 1 and the sub-plate 2 is adjustable to meet the reading needs of different users, thereby improving the overall compatibility and practicality of use, and the adjustment operation is simple and easy to use.
