DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 As shown, a handwriting display that is easy to rotate includes a display 1, and a placement structure 2 is provided on the back of the display 1. The placement structure 2 includes a support base 201, and the support base 201 is rotatably connected to the display 1. A slide groove 202 is provided on the support base 201, and the support base 201 is slidably connected to a lifting block 205 through the slide groove 202. The back of the display 1 is fixedly connected to a guide bar 204, and the side of the lifting block 205 is rotatably connected to a guide wheel 206, and the guide wheel 206 conflicts with the side of the guide bar 204. The bottom side of the lifting block 205 is fixedly connected to a placement groove 203, and the inner side of the placement groove 203 is connected to a fixed structure 3.

[0024] As a technical optimization solution of the present invention, the guide bar 204 is an elliptical structure, and the center point of the guide bar 204 is on the same straight line as the rotating axis of the support seat 201. The support seat 201 is slidably connected to a resistance block 207 through a slide groove 202. A first spring 208 is fixedly connected between the side of the resistance block 207 and the support seat 201. The resistance block 207 and the lifting block 205 are in conflict with each other. The first spring 208 pushes the resistance block 207 so that the resistance block 207 will maintain pressure on the bottom side of the lifting block 205, thereby better keeping the lifting block 205 always near the bottom side of the display 1 as the display 1 rotates, making it convenient to take the electromagnetic pen. The side of the display 1 is provided with a positioning groove 2 09, the positioning groove 209 is in a "cross" shape, and the end of the support seat 201 is slidably connected with a positioning rod 210, and the end of the positioning rod 210 is in a hemispherical structure. The diameter of the positioning rod 210 is equal to the opening diameter of the positioning groove 209, and two positioning rods 210 are symmetrically provided. The spherical end of the positioning rod 210 is in conflict with the display 1 through the positioning groove 209, and a second spring 211 is fixedly connected between the positioning rod 210 and the support seat 201. A positioning rod 210 is provided on the support seat 201, and combined with the "cross" shaped positioning groove 209 on the back of the display 1, the display 1 can be positioned at various rotation angles to ensure the stability of the display 1 during use, and at the same time facilitate the adjustment of the angle of the display 1.

[0025] As a technical optimization solution of the present invention, the fixed structure 3 includes a storage slot 301, and the inner side of the placement slot 203 is rotatably connected to the storage slot 301, and the storage slot 301 is in a "U"-shaped structure. The side of the storage slot 301 conflicts with the placement slot 203, and both ends of the storage slot 301 are fixedly connected to a torsion spring 302, and the other end of the torsion spring 302 is fixedly connected to the inner side of the placement slot 203. Both ends of the storage slot 301 are provided with an extraction slot 303, and the extraction slot 303 is in a semicircular structure. A storage slot 301 for storing the electromagnetic pen is provided in the placement slot 203. The "U"-shaped storage slot 301 can maintain an open state by the action of the torsion springs 302 at both ends, thereby preventing the electromagnetic pen from falling in the storage state. When taking the electromagnetic pen, the electromagnetic pen can be taken out by rotating the storage slot 301 and through the extraction slots 303 opened at both ends of the storage slot 301, which is convenient for use.

A positioning rod 210 is provided on the support base 201. Combined with the "cross" shaped positioning groove 209 on the back of the display 1, the display 1 can be positioned at various rotation angles to ensure the stability of the display 1 during use, while facilitating the adjustment of the angle of the display 1. At the same time, in order to facilitate the user to take and place the electromagnetic pen at different placement angles of the display 1, the placement groove 203 on the lifting block 205 will move as the lifting block 205 slides in the slide groove 202, and when the display 1 rotates, the guide bar 204 on the back of the display 1 will drive the lifting block 205 to move up and down in the vertical direction through the rotation of the guide wheel 206, thereby maintaining the position for placing the electromagnetic pen The placement slot 203 can always be located at the bottom side of the display 1 and remain exposed. At the same time, the first spring 208 pushes the resistance block 207, so that the resistance block 207 will maintain pressure on the bottom side of the lifting block 205, thereby better keeping the lifting block 205 always near the bottom side of the display 1 as the display 1 rotates, thereby achieving the purpose of the user taking and storing the electromagnetic pen at any time. A storage slot 301 for storing the electromagnetic pen is provided in the placement slot 203. The "U"-shaped storage slot 301 can maintain an open state through the action of the torsion springs 302 at both ends, thereby preventing the electromagnetic pen from falling in the storage state. When taking the electromagnetic pen, the storage slot 301 can be rotated and the electromagnetic pen can be taken out through the extraction slots 303 opened at both ends of the storage slot 301, which is convenient for use.
