Rotate the main unit and the bottom plate to open, and adjust the main unit and the bottom plate to a suitable angle. When the main unit is opened, the shaft is driven to rotate, so that the cam at the bottom of the shaft contacts the positioning teeth, and the positioning teeth are fixed at an angle by cooperating with the tooth grooves of the cam; S2. Press down the pressing column on the top of the housing, so that the stop column and the motion block are forced to compress the spring, so that the fixed teeth on the top of the motion block are disengaged from the fixed opening on the pressure plate, so that the pressure plate is rotated out from the inside of the placement slot by the tension of the tension spring; S3. Prevent the book from being on the top of the bottom plate, so that one side of the book is close to the side of the housing, and the pressure plate is located on the top of the book, so that the paper of the book is relatively flat through the pressure plate; S4. Scan the information on the book through the camera, and display the content of the textbook selected by the outline box, and use the button panel on the housing to operate the box selection module to adjust the size of the outline box; S5. Operate the mode drive module through the key panel to switch the host to the reading mode or the follow-up mode in sequence; S6. Operate the voice switching module through the key panel to switch the host to English mode or Chinese mode in sequence; S7. Use the reading pen matched with the host to circle the content on the book, the camera captures the circling action, the motion recognition module recognizes the circling action, and enables the host to read out the circled book content. Use the reading pen matched with the host to click on the content on the book, the camera captures the clicking action, the motion recognition module recognizes the clicking action, and enables the host to pause reading the content.

4. The point reading operation method for primary school students according to claim 3 is characterized in that: In step S7, the movement of the finger is captured by the camera, and when the finger stays at the designated position for a time exceeding a threshold, it is determined that a circle selection action is made, the image captured by the camera is analyzed, and the circled area on the book is calculated by a difference frame algorithm.
