[0025] As a technical optimization solution of the present invention, a stylus pen 7 is installed on the handwriting screen body 1, a hanging rope 8 is installed between the stylus pen 7 and the handwriting screen body 1, a placement slot 9 is provided on the handwriting screen body 1, a connecting block 208 is fixedly connected to the support base 203, and two fans 10 are installed in the installation frame 201. When used in summer, the handwriting screen body 1 can be cooled by the fans 10 to ensure the smoothness of use of the handwriting screen body 1.

[0026] As a technical optimization solution of the present invention, the mounting frame 201 is installed with the handwriting screen body 1 through a mounting structure 3, and the mounting structure 3 includes two mounting rods 301 fixedly connected to the bottom of the handwriting screen body 1, and the mounting rods 301 are slidably connected to the mounting frame 201. There are two mounting blocks 302 slidably connected in the mounting frame 201, and the two mounting blocks 302 are respectively engaged with the two mounting rods 301. A screw rod 303 is rotatably connected in the mounting frame 201, and the mounting block 302 is threadedly connected to the screw rod 303. The thread directions at both ends of the screw rod 303 are opposite, and both ends of the screw rod 303 are provided with an inner hexagonal groove for use with a hexagonal wrench. The cross-section of 302 is an "L"-shaped structure, and the length of the screw rod 303 is the same as the length of the mounting frame 201. When the handwriting screen body 1 needs to be installed between the mounting frame 201, the mounting rod 301 at the bottom of the handwriting screen body 1 can be connected to the mounting frame 201, and then the hexagonal wrench is inserted into the hexagonal groove at the end of the screw rod 303. The screw rod 303 is rotated by the hexagonal wrench. When the screw rod 303 rotates, the thread drives the two mounting blocks 302 to slide toward each other. The mounting blocks 302 will slide until they are engaged with the mounting rod 301, thereby completing the installation of the handwriting screen body 1. The handwriting screen body 1 is installed by driving the two mounting blocks 302 through the screw rod 303, thereby improving the installation efficiency of the handwriting screen body 1.

[0027] As a technical optimization solution of the present invention, a limiting structure 4 is provided between the mounting frame 201 and the support seat 203, and the limiting structure 4 includes a sliding column 401 slidably connected to the mounting frame 201, and a limiting column 402 is fixedly connected to the sliding column 401. A plurality of limiting holes 403 are provided on the support seat 203, and the limiting column 402 is engaged with one of the limiting holes 403. A pull plate 406 is fixedly connected to the sliding column 401, and a plurality of the limiting holes 403 are distributed in a circular array about the center of the fixed shaft 202. The sliding column 401 is fixedly connected to the limiting column 402. There is a fixing ring 404, and a spring 405 is provided between the fixing ring 404 and the mounting frame 201. When writing is needed on the handwriting screen body 1, the user takes the stylus 7 to write on the handwriting screen body 1. When in use, the anti-peep and explosion-proof film 6 can prevent others from peeping at the personal information of the user on the handwriting screen body 1, and can also prevent the handwriting screen body 1 from being broken by external force. When the angle of the handwriting screen body 1 needs to be adjusted, the pull plate 406 is pulled, and the pull plate 406 drives the slide column 401 to slide, and the slide column 401 drives the fixing ring 404 to move. When the handwriting screen body 1 is in the state of being moved, the spring 405 contracts when the fixing ring 404 moves, and at the same time, the sliding column 401 drives the limiting column 402 to no longer engage with the limiting hole 403. At this time, the handwriting screen body 1 and the fixed shaft 202 and the support base 203 can be rotated. When rotating, the support frame 206 will rotate downward under the action of gravity. When it is rotated to a certain angle, the support frame 206 is located in two of the adjustment grooves 207. The support frame 206 contacts the support base 203, which is convenient for supporting the handwriting screen body 1, thereby improving the stability of the handwriting screen body 1. Moreover, the handwriting screen body 1 can be rotated to cooperate with the support base 203. The use of the support frame 206 makes it easy to adjust the angle of the handwriting screen body 1 according to the table at different heights, thereby improving the user comfort. At the same time, the pull plate 406 can be loosened, so that the limiting column 402 is engaged with one of the limiting holes 403 under the action of the spring 405. By engaging the limiting column 402 with the support base 203, the adjusted handwriting screen body 1 is conveniently fixed, thereby improving the stability of the handwriting screen body 1. At the same time, through the mounting hole on the connecting block 208, bolts can be passed through the mounting hole on the connecting block 208, and then the support base 203 can be fixed to the place where it is used.

[0028] When the present invention is in use, when it is necessary to write on the handwriting screen body 1, the user takes the stylus 7 to write on the handwriting screen body 1. When in use, the anti-peep and explosion-proof film 6 can prevent others from peeping at the personal information of the user on the handwriting screen body 1, and can also prevent the handwriting screen body 1 from being broken by external force. When it is necessary to adjust the angle of the handwriting screen body 1, the pull plate 406 is pulled, and the pull plate 406 drives the slide column 401 to slide, and the slide column 401 drives the fixed ring 404 to move. When the fixed ring 404 moves, the spring 405 contracts, and the slide column 401 drives the limit column 402 is no longer engaged with the limiting hole 403, and the handwriting screen body 1 and the fixed shaft 202 and the support base 203 can be rotated at this time. During the rotation, the support frame 206 will rotate downward under the action of gravity. When it is rotated to a certain angle, the support frame 206 is located in two of the adjustment slots 207. The support frame 206 conflicts with the support base 203, which is convenient for supporting the handwriting screen body 1 and improving the stability of the handwriting screen body 1. In addition, the handwriting screen body 1 can be rotated, and the use of the support base 203 and the support frame 206 is convenient for adjusting the angle of the handwriting screen body 1 according to the table at different heights, thereby improving The user can use the comfort, and at the same time, the pull plate 406 can be loosened, so that the limiting column 402 is engaged with one of the limiting holes 403 under the action of the spring 405, and the limiting column 402 is engaged with the support seat 203, which is convenient for fixing the adjusted handwriting screen body 1, thereby improving the stability of the handwriting screen body 1. At the same time, through the mounting hole on the connecting block 208, the bolt can be passed through the mounting hole on the connecting block 208, and then the support seat 203 can be fixed to the place where it is used. When it is necessary to install it between the handwriting screen body 1 and the mounting frame 201, the mounting rod 301 at the bottom of the handwriting screen body 1 can be connected to the mounting frame 201. The mounting frame 201 is plugged in, and then inserted into the hexagonal groove at the end of the screw rod 303 through the hexagonal wrench, and the screw rod 303 is rotated by the hexagonal wrench. When the screw rod 303 rotates, the thread drives the two mounting blocks 302 to slide toward each other, and the mounting blocks 302 will slide until they are engaged with the mounting rod 301, thereby completing the installation of the handwriting screen body 1. The screw rod 303 drives the two mounting blocks 302 to install the handwriting screen body 1, which improves the installation efficiency of the handwriting screen body 1. When used in summer, the fan 10 can be used to dissipate heat from the handwriting screen body 1 to ensure smooth use of the handwriting screen body 1.
