The invention relates to a book holder that holds books in an open position, thus leaving the hands free for reading. It consists of a central joint for adjusting the opening angle of the book, linear guides for adapting to different book sizes, and clamps comprising a hook with transparent tips and a spring system in which the book halves are clamped. The book holder can be used lying down, standing up, or sideways on various surfaces (table, bed, lap, in the hand). It is foldable and easily portable, ideal for mobile use. The flexible design securely holds books of different types and sizes and allows for easy page turning without having to reposition the book. The book holder is suitable for relaxed reading as well as for research or studying.

The utility model discloses an achievement conversion information acquisition system, and relates to the technical field of information service. The storage device comprises the main body and the storage mechanism, the storage mechanism comprises the fixing plate, the storage mechanism is arranged, the sliding blocks are clamped in the sliding grooves in a sliding mode, and the storage bag is fixedly connected between every two sliding blocks, so that an operator can select different storage bags for classified storage according to different achievements; the information management efficiency and accuracy are improved, the sliding blocks can slide in the sliding grooves, the positions and the intervals of the storage bags can be flexibly adjusted according to actual needs, when more information needs to be stored, the intervals of the adjacent storage bags can be properly increased so as to contain more data, when the information is less, the intervals can be reduced, the applicability and the use experience are improved, and the practicability is high. Operators do not need to switch among multiple devices, the working efficiency is improved, and the printer on the inner side of the printing opening in the outer surface of the main body can print information in the system in a paper form.

The invention relates to the technical field of stationery, in particular to an exercise book anti-tilt positioning clamp with an inclination angle monitoring and reminding function, which comprises a positioning clamp main body, an automatic inclination angle testing system, a control module, a reminding module, a power supply module and an adjusting key, the device is clamped at the edges of an exercise book and a desktop through the clamping assembly, after a power supply is started, the inclination angle automatic test system collects a gravity component signal, and angle data is obtained through calibration, filtering and conversion and is transmitted to the control module. And the control module adopts a dynamic adaptive threshold comparison algorithm to judge whether the angle exceeds the standard or not, triggers acousto-optic reminding if the angle exceeds the standard, and stops reminding after the angle is recovered. According to the invention, a user can customize parameters by adjusting the keys to adapt to different scenes. The device is light in structure, accurate in detection and easy and convenient to operate, and can better remind students of standardizing exercise book placement in time by monitoring the inclination angle so as to assist in developing a good writing habit.
