[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 , the utility model provides a technical solution:

[0025] A marking device for teaching English comprises a mounting shell 1 and an adjusting plate 2. The adjusting plate 2 is provided with four groups of limit slots 3 at equal intervals inside. The four groups of limit slots 3 are provided with writing components 4 for marking. The mounting shell 1 is provided with a cavity inside. The cavity is provided with a lifting component 5 for adjusting the height of the adjusting plate 2. The adjusting plate 2 is connected to the moving end of the lifting component 5. The utility model can complete the marking operation at one time, which is beneficial to improving the marking efficiency. The lines are spaced uniformly and evenly distributed, which is beneficial to improving the teaching quality.

[0026] The writing assembly 4 includes four sets of sleeves 401, which are slidably connected to the inside of four sets of limiting slots 3, and the inside of the four sets of sleeves 401 is slidably plugged with chalk sleeves 402, one end of the four sets of sleeves 401 is fixedly connected to a fixing plate 403, and one side of the fixing plate 403 is fixedly connected to a pull plate 404;

[0027] The backing spring 6 is also included. One end of the backing spring 6 is fixedly connected to the inner wall of one side of the sleeve 401. The other end of the backing spring 6 is fixedly connected to one end of the chalk sleeve 402. By setting the backing spring 6, when one end of the chalk contacts the blackboard, a certain buffering effect is achieved. During the writing process, the friction force on the chalk may be different, resulting in different wear and tear of the chalk, resulting in different lengths. By setting the backing spring 6, it can be ensured that one end of each chalk can directly contact the blackboard.

[0028] Each group of limit slots 3 is provided with a slide groove 7 at the inner top and the inner bottom. The slide groove 7 is slidably connected to the limit block 8. The sleeve 401 is slidably inserted into the limit block 8. The slide groove 7 and the limit block 8 are used in coordination to limit the sleeve 401. When a group of lines is drawn, the pull plate 404 can be pulled to move the sleeve 401 to the side away from the blackboard, so that one end of the chalk is separated from the blackboard, thereby facilitating the lifting assembly 5 to adjust the height of the writing assembly 4.

[0029] The lifting assembly 5 includes a ball screw 501, the two ends of which are rotatably mounted on the inner top and inner bottom of the mounting shell 1, respectively. The top of the ball screw 501 passes through the mounting shell 1 and is connected to a drive motor 502. The drive motor 502 is fixedly mounted on the top of the mounting shell 1. The drive motor 502 is configured as a forward and reverse stepping motor. A drive block 503 is threadedly connected to the outer wall of the ball screw 501. A connecting block 504 is fixedly connected to one side wall of the driving block 503. The adjusting plate 2 is fixedly connected to one side wall of the connecting block 504.

[0030] A first rectangular groove 9 is formed on one side wall of the mounting shell 1, and the connecting block 504 is slidably connected to the inside of the first rectangular groove 9;

[0031] A grating ruler 10 is fixedly connected to one side wall of the mounting shell 1, a second rectangular groove 14 is provided on one side wall of the mounting shell 1, a mounting block 11 is slidably connected inside the second rectangular groove 14, the mounting block 11 is fixedly connected to one side wall of the driving block 503, a reading head 12 adapted to the grating ruler 10 is fixedly connected to one side wall of the mounting block 11, the reading head 12 and the grating ruler 10 can detect the position of the adjustment plate 2 in real time, and feed back the position information to the control system (not shown in the figure), and the control system adjusts the position of the adjustment plate 2 according to the fed-back position information, thereby realizing high-precision position control;

[0032] Four groups of anti-sliding blocks 13 are fixedly mounted on one side wall of the mounting shell 1 , and the four groups of anti-sliding blocks 13 are symmetrically arranged in pairs.

[0033] Working principle: When the utility model is used, the chalk is inserted into the inside of the chalk sleeve 402, and the ball screw 501 is driven to rotate by the output shaft of the driving motor 502, so that the driving block 503 can be driven to reciprocate in the vertical direction, and then the adjusting plate 2 can be driven to reciprocate in the vertical direction through the connecting block 504, so as to achieve the effect of adjusting the height of the writing component 4. The initial position of the writing component 4 is located in the limiting groove 3 and close to the side of the mounting shell 1. After adjusting the writing component 4 to a suitable position, the pull plate 404 is manually pulled to move the fixed plate 403 toward the side away from the mounting shell 1. While pulling the pull plate 404, the pull plate 404 is pressed slightly toward the direction of the blackboard, so that four groups of lines can be drawn at one time, and then the writing component is moved to a suitable position, and the above steps are repeated again to complete the marking work of another group of lines, which can greatly improve the marking efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
