The technical problem to be solved by the present invention is to provide a cultural media book placement device that can place books and periodicals neatly, beautifully, not easily lost or damaged, and reduce economic losses. In order to solve the above technical problems, the present invention provides such a cultural media book placement device, including a base plate, etc.; an adjustment device is provided on the top of the base plate, and a movable plate is connected to the adjustment component of the adjustment device. The movable plate is vertically arranged symmetrically on the left and right, and the lower part of the inner side surface of the movable plate is connected to a fixing by bolt connection. The outer side of the top of the fixed block is vertically connected to a positioning rod by bolt connection. A telescopic device is provided between the two movable plates, and a positioning hole is opened on the telescopic device, and the positioning rod is located in the positioning hole. The present invention achieves the effect of placing books and periodicals neatly, beautifully, not easily lost or damaged, and reducing economic losses.

[0004] A telescopic device is provided between the two movable plates of the device, so that the two ends of the book can be stretched by the telescopic device, but the device does not have a structure for stretching the upper and lower ends of the book. Books are relatively soft objects. If the two ends of the books are not stretched and supported, the books will fold together, which not only affects the aesthetics of the books, but also easily causes the books to be deformed if placed like this for a long time.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original structure of the book placement device. Utility Model Content

[0015] Compared with the prior art, the beneficial effect of the utility model is that the book placement device is provided with:

[0016] 1. The stretching structure fixes the upper and lower ends of the books and periodicals on the outside of the adjustment rod. By running the servo motor, the output end of the servo motor drives the counter-rotating threaded rod to rotate. The rotation of the counter-rotating threaded rod drives the threaded connectors connected at both ends to move in the opposite direction, so that the upper and lower ends of the books and periodicals are stretched up and down, so that the books and periodicals are placed flat on the outside of the book placement device, improving the aesthetics of the book placement;

[0017] Furthermore, when the adjusting rod moves up and down, the sliding block will slide along the outer side of the limiting rod, so that the adjusting rod is limited in angle by the sliding of the sliding block, thereby preventing the adjusting rod from rotating when it moves up and down;

[0018] Furthermore, a guide wheel is installed at the lower end of the support base, and the user can adjust the position of the book placement device through the guide wheel, so that the book placement device is placed in a suitable position;
