[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-5 An angle-adjustable writing practice board includes a writing board 1, on which an adjustment mechanism 2 is provided; the adjustment mechanism 2 includes a base 201, with universal wheels 202 fixedly installed at each of the four corners of the base 201, and a swivel seat 203 fixedly installed on one side of the base 201. Several positioning grooves 204 are arranged side by side on the upper part of the swivel seat 203, and a shaped seat 205 is rotatably installed through the positioning grooves 204. A first support rod 206 is fixedly installed on the upper side of the shaped seat 205.

[0024] See Figure 2 and Figure 3 Furthermore, it is found that each of the four casters 202 is fixedly installed with a long plate between it and the base 201, the swivel seat 203 is located at the upper 1 / 4 position of the base 201, the spacing between the several positioning grooves 204 is consistent, and the first support rod 206 is adapted to the several positioning grooves 204.

[0025] Specifically, four long plates connect the casters 202 to the base 201, allowing the base 201 to move freely. This further controls the swivel base 203 at the 1 / 4 position on the base 201, increasing the stability of the first support rod 206. The swivel base 203 has several positioning slots 204 evenly spaced to ensure that the first support rod 206 is positioned on the base 201 without external force. When an external force is applied to the first support rod 206, it can rotate on the swivel base 203, thereby achieving the effect of adjusting the angle of the writing board 1.

[0026] Example 2

[0027] Combination Figure 1 and Figure 4 The writing board 1 is provided with a fixing mechanism 3, which includes a first support 301 and a second support 302. The first support 301 and the second support 302 are fixedly installed side by side at the lower ends of the writing board 1. A second support rod 303 is rotatably installed inside the second support 302. A buckle groove 304 is opened on the first support rod 206. A first limiting groove 305 is opened on one side of the writing board 1. A column 306 is fixedly installed at one end of the base 201. A second limiting groove 307 is opened at one end of the column 306.

[0028] See Figure 4 Furthermore, based on Embodiment 1, the first support 301 is rotatably connected to the first support rod 206, the second support 302 is adapted to the buckle groove 304, and a rubber strip is fixedly installed inside the buckle groove 304. The second support rod 303 is adapted to the first limiting groove 305 and the second limiting groove 307 respectively, and a rubber strip is fixedly installed inside both the first limiting groove 305 and the second limiting groove 307.

[0029] Specifically, by installing a first support 301 and a second support 302 on the writing board 1, and rotating the first support 301 onto the first support rod 206, when rotating the first support 301 so that the second support 302 is embedded in the buckle groove 304, the writing board 1 is vertically installed and can be rotated in conjunction with the first support rod 206. When rotating the first support 301 so that the second support 302 is perpendicular to the base 201, the second support rod 303 is further controlled to rotate and be embedded into the second limiting groove 307, thus fixing the writing board 1. The rubber strip serves to increase friction.

[0030] In actual operation, the casters 202 are connected to the base 201 by four long plates, allowing the base 201 to move freely. This further controls the swivel seat 203 at the 1 / 4 position on the base 201, increasing the stability of the first support rod 206. The swivel seat 203 has several positioning grooves 204 evenly spaced on it, ensuring that the first support rod 206 is positioned on the base 201 without external force. When an external force is applied to the first support rod 206, it can rotate on the swivel seat 203, thereby achieving the effect of adjusting the angle of the writing board 1.

[0031] By installing a first support 301 and a second support 302 on the writing board 1, and rotatably mounting the first support 301 on the first support rod 206, the writing board 1 is vertically mounted when the first support 301 is rotated so that the second support 302 is embedded in the buckle groove 304. The writing board 1 can be rotated in conjunction with the first support rod 206. When the first support 301 is rotated so that the second support 302 is perpendicular to the base 201, the second support rod 303 is further controlled to rotate and be embedded in the second limiting groove 307, thus fixing the writing board 1. The rubber strip serves to increase the friction.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
