The clamping piece is rotationally connected with the bottom plate, for example, the clamping piece is rotationally connected with the bottom plate through a rotating shaft, and the clamping piece can also be indirectly connected with the bottom plate through a transmission part.

The book holder of the utility model can also have linkage function, the said retaining piece is connected with the transmission part, when the clamping piece moves to the direction of the bottom plate, the retaining piece moves to the direction away from the bottom plate, when the clamping piece moves to the direction away from the bottom plate, the retaining piece moves to the direction of the bottom plate, compared with the book holder without linkage function, the utility model can finish the clamping of thicker pages under the condition of less clamping piece pressing down distance, the utility model provides two schemes, as for the concrete connection mode of the retaining piece and the bottom plate, in some embodiments, the retaining piece is rotationally connected with the bottom plate, for example, the retaining piece can be rotationally connected with the bottom plate through a rotating shaft, in other embodiments, the retaining piece is slidingly connected with the bottom plate, for example, the bottom plate is provided with a through hole for the retaining piece to pass through, and the retaining piece is slidingly connected with the bottom plate through the through hole.

The driving part can be directly connected with the transmission part, also can be indirectly connected with the transmission part through the retaining piece, when the driving part drives the clamping piece through the retaining piece, the clamping piece moves towards the direction far away from the bottom plate, the retaining piece moves towards the direction of the bottom plate, the external force presses down the clamping piece, and when moving towards the direction of the bottom plate, the retaining piece moves towards the direction far away from the bottom plate.

The torsion spring for generating clamping force of the existing book end is usually exposed in the visible range of consumers, which is not beneficial to the appearance, and the utility model does not limit the position of the driving part in particular, for example, the driving part can be arranged on the back of the bottom plate completely, can not be visible to consumers, and can be arranged on the front of the bottom plate completely and is wrapped completely. Of course, there are also some driving parts provided on the front surface of the base plate and some driving parts provided on the back surface of the base plate, and then some driving parts provided on the front surface of the base plate are completely wrapped.
