[0026] Specifically, the inner wall of support 63 is fixedly connected with fixed frame 612, the inner wall of fixed frame 612 is fixedly connected with magnetic plate one 613, the lower side of the rear of body 1 is equipped with recess 614, the inner wall of body 1 at recess 614 is fixedly connected with magnetic plate two 615, the position of magnetic plate one 613 can be supported and fixed through fixed frame 612, to ensure that magnetic plate one 613 can contact with magnetic plate two in the closed state, to ensure the stability of the adsorption between magnetic plate one and magnetic plate two.
[0027] Specifically, the surface of positioning frame 61 and the left side of support 63 is in contact, and the upper end of support 63 is arc-shaped.
[0028] In the embodiment: the left side of support 63 can be supported through the cooperation of positioning frame 61 and pivot 62, and the rotation axis 62 of the left side can be limited, to ensure that support 63 rotates in the specified direction in the rotating state.
[0029] Specifically, the limiting frame 64 is in contact with the surface on the right side of the support 63. Through the cooperation of the limiting frame 64 and the pressing column 69, the right side of the support 63 can be supported, and the rotating shaft 62 in the right side of the support 63 can be limited, so as to ensure that the support 63 rotates in a specified direction during rotation.
[0030] In this embodiment, the catch 68 is in sliding connection with the inner wall of the mounting cavity 65, and the catch 68 penetrates the surface on the right side of the support 63.

[0034] In this embodiment, through the cooperation of the magnetic plate one and the magnetic plate two, the lower end of the support 63 in the closed state can be constrained, so as to ensure the stability of the lower end of the support 63 in the closed state.
[0035] Working principle: when using the handwriting screen, open the switch of the handwriting screen, and the handwriting screen works through the power supply of the battery in the machine body 1. When the handwriting screen works, the user can draw on the handwriting screen through the handwriting pen, and the user can draw with the assistance of the control button 3 on the side of the machine body 1. When the power of the machine body 1 is too low, the user can charge the machine body 1 through the charger and the charging port 4.
[0036] When the user needs to use the handwriting pen, the pressing column 69 is pushed, the pressing column 69 pushes the force bearing plate 66, the force bearing plate 66 extrudes the limiting spring 67, and the catch 68 is pulled and gradually separated from the limiting frame 64. When the catch 68 is completely separated from the limiting frame 64, the catch 68 loses the locking effect on the support 63, and then the support 63 is rotated. The support 63 rotates in a specified direction under the guidance of the positioning frame 61, the rotating shaft 62, the limiting frame 64 and the pressing column 69.
