[0040] When the user moves the hand away from the infrared sensor 4 above, the motor 62 is turned off, and the lifting mechanism 6 and the rotating mechanism 7 are stopped as a whole, making it convenient for people to take out books; then people manually move the hand closer to the infrared sensor 4 below, and the infrared sensor 4 below detects that the distance between the hand and the infrared sensor 4 reaches the preset value, thereby controlling the motor 62 to start, and the output shaft of the motor 62 rotates to drive the threaded rod 63 to rotate, and then the threaded rod 63 is driven upward by the action of the fixed threaded tube 5, and the threaded rod 63 drives the motor 62, the sliding frame 61, the fixed box 64, the fixed cam 71, the rotating plate 72, the first bevel gear 73, the motor 74 and the second bevel gear 75 to move upward. 5 drives the first bevel gear 73 to rotate, and then drives the rotating plate 72 to rotate, and the rotating plate 72 drives the books to rotate, which makes it convenient for people to find books, and there is no need to walk around the bookcase to find books. When people find the books they need, they can take their palms off the infrared sensor 4 below, the motor 74 is turned off, the rotating mechanism 7 stops running, and people can take out the books they need; when people manually approach the upper infrared sensor 4 again, the upper infrared sensor 4 detects that the distance between it and the hand reaches a preset value, and then controls the motor 62 to reverse, reset and shut down, the output shaft of the motor 62 reverses and drives the threaded rod 63 to reverse, and then drives the threaded rod 63 downward under the action of the fixed threaded tube 5, and the threaded rod 63 drives the motor 62, the sliding frame 61, the fixed box 64, the fixed cam 71, the rotating plate 72, the first bevel gear 73, the motor 74 and the second bevel gear 75 to move downward, reset and retract, so as to reduce the accommodation space and avoid the bookcase occupying the limited space in the room.

After accessing, the cover 91 is reversed and closed, and the sliding buckle 93 is released. Then, the sliding buckle 93 is driven to move backward and reset under the action of the second telescopic spring 94. The sliding buckle 93 limits the cover 91 to prevent children from damaging the books in the shell 2.

Then, under the action of the fourth telescopic spring 112 being reset, the second sliding plate 111 is driven to move upward to limit the book, preventing the book from moving inward and separating from the clamping plate 105. When the book needs to be taken out, the second sliding plate 111 is moved downward to reset, the fourth telescopic spring 112 is compressed, and the rotating buckle 113 is reversed again.
