[0038] Working principle: When using the present invention, Figure 1 , 2 , 3 and Figure 4 As shown, the teacher can authenticate the identity through the identity authentication module 607 in the teacher terminal 6 to enter the operation interface, and then use the task distribution module 606 to distribute the homework, and then the student uses the identity authentication module 8 in the student terminal 1 to authenticate the identity to enter the class interface, and then use the task receiving and replying 7 to accept and reply to the homework, and then Figure 4 , 5 , 6, 7 and Figure 8 As shown, the student can use a pen to write normal homework on the homework book, and then use the handheld shell 10 after writing, and then press the second trigger button 13 to scan the answers written on the homework book through the input instrument body 202 and upload it to the student terminal 1, and then transmit it to the server 4 until it is distributed to the teacher terminal 6. The teacher uses the correction module 601 to check the homework. In this process, it is completely avoided that the student does not receive the computer and affects the homework efficiency.

[0039] like Figure 5 , 6 , 7 and Figure 8 As shown, by pressing the first trigger button 9, the motor 17 is started to drive the first rotating shaft 15 to rotate, and the first rotating shaft 15 drives the internal threaded sleeve 21 to rotate by the transmission of the universal joint 23. Because the internal threaded sleeve 21 is threadedly connected with the threaded rod 20, the threaded rod 20 can be driven to move inside the internal threaded sleeve 21 while the internal threaded sleeve 21 rotates, thereby driving the data entry instrument body 202 to move, thereby adjusting the height of the data entry instrument body 202, thereby expanding and reducing the data entry width of the data entry instrument body 202, and then using the second pulley 16 and the second synchronous belt 19, the winding rod 24 can be driven to wind the metal wire 25, so that the metal wire 25 is used to pull the two rotating plates 143 to expand and reduce, so as to expand the matching range;

During the movement, the telescopic rod 142 can be used to limit the verticality of the two moving blocks 144 to the plane of the desk. Then, the rolling friction of the mounting groove 145 can be used to drive the synchronous shaft 28, the first pulley 29 and the first synchronous belt 30 to rotate, thereby driving the friction belt 146 to rotate. The rotation of the friction belt 146 can cause the friction rolling between the planes to prevent the moving block 144 from moving in a straight line during the movement process, thereby preventing students from entering pictures in a curved shape and affecting the teacher's marking. The whole process is more suitable for students' use, more suitable for the non-discriminatory interaction between students and teachers, and can also increase students' writing ability.
