[0002] English word formation has its rules, and only when the word formation rules are well mastered, can the words be well, quickly and accurately remembered. The core part of the English word formation method is the root, and the meaning of the word is mainly embodied by the root of the word. The root can form a word alone or combine with each other to form a word, and the prefix and suffix can change the part of speech and meaning of the word. (Root and affix are called word formation elements) That is, a word is generally composed of three parts: root, prefix and suffix. The root determines the meaning of the word, the prefix changes the meaning of the word, and the suffix determines the part of speech of the word.
[0003] The existing root demonstration device uses a root plate that is separate, and in order to let the learner see clearly, the root plate is not small, so the root that can be accommodated on the demonstration device is limited, and when learning more root usage, the root plate on the demonstration device needs to be replaced, which is more troublesome.

[0007] As a further description of the above technical scheme:
[0008] The demonstration box is provided with three groups of unwinding rollers and winding rollers, the selection element includes a control gear rotatingly arranged in the demonstration box, an unwinding gear fixedly sleeved on the unwinding roller and a winding gear fixedly sleeved on the winding roller, a plurality of recesses are arranged on the rear side of the demonstration box, the mounting shaft of each control gear penetrates out of the demonstration box and is fixedly connected with a lever, and the demonstration box is provided with a positioning element for fixing the lever.
[0009] As a further description of the above technical scheme:
[0010] The positioning member comprises a positioning plate fixed on the outer surface of the demonstration box at the edge of the recess, and a plurality of positioning holes are uniformly arranged in the positioning plate, and a positioning rod is slidably arranged in the dialing rod and is inserted into the positioning hole.
[0011] Further description of the above technical solution:
[0012] The positioning rod is in L shape, and an outer fixing sleeve is provided with a limiting ring block for preventing the positioning rod from being separated from the dialing rod.
[0013] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are:
[0014] In the present application, the flexible root band is matched with the adjusting member, so that the demonstration device can accommodate more roots, and is more convenient to use, and the original hard root plate does not need to be frequently replaced. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0021] Embodiment 1:
[0022] As Figures 1-4As shown, an English word root demonstrator includes a demonstrator box 1 and supports 2 on both sides of the demonstrator box 1. The demonstrator box 1 has three parallel demonstrator openings 3 on its front side. A back plate 4 is fixedly installed inside the demonstrator box 1. The demonstrator box 1 is equipped with flexible prefix tape, word root tape 7, and suffix tape. The prefix tape, word root tape 7, and suffix tape are all attached to the side of the back plate 4 facing the demonstrator openings 3. The demonstrator box 1 is equipped with three sets of adjustment mechanisms for controlling the prefix tape, word root tape 7, and suffix tape, respectively. By utilizing the cooperation of the flexible word root tape 7 and the adjustment mechanisms, the demonstrator can accommodate more word roots, making it easier to use and eliminating the need to frequently replace the original rigid word root board.
[0023] Example 2:
[0024] The technical solution is basically the same as that in Embodiment 1, except that, as Figures 1-4 As shown, the demonstration box 1 contains three sets of unwinding rollers 5 and rewinding rollers 6. The selection components include a control gear 8 rotatably mounted inside the demonstration box 1, an unwinding gear 9 fixedly sleeved on the unwinding roller 5, and a rewinding gear 10 fixedly sleeved on the rewinding roller 6. Multiple recesses are provided on the rear side of the demonstration box 1. The mounting shaft of each control gear 8 extends through the demonstration box 1 and is fixedly connected to a lever 11. The lever 11 rotates the control gear 8, which in turn rotates the unwinding gear 9 and the rewinding gear 10, causing the corresponding unwinding roller 5 and the rewinding roller 6 to unwind and rewind synchronously, achieving the effect of changing the display surfaces of the prefix strip, root strip 7, and suffix strip. The demonstration box 1 is equipped with a positioning component for fixing the lever 11. The positioning component includes a positioning plate 12 fixedly mounted on the outer surface of the demonstration box 1 at the edge of the recess. Multiple positioning holes are evenly distributed within the positioning plate 12. A positioning rod 13, which slides within the lever 11, is inserted into the positioning hole. The positioning rod 13 is L-shaped and is externally fixed with a limiting ring block 14 to prevent the positioning rod 13 from disengaging from the lever 11. When the prefix band, root band 7 and suffix band rotate to the display surface, the positioning rod 13 is inserted into the corresponding positioning hole in the corresponding positioning plate 12, which can fix the lever 11 and thus fix the control gear 8, unwinding gear 9 and rewinding gear 10, preventing the prefix band, root band 7 and suffix band from loosening.
[0025] Working principle: When using this demonstrator, the prefix band, root band 7, and suffix band need to be adjusted in sequence. Moving the corresponding lever 11 will rotate the control gear 8, which in turn rotates the unwinding gear 9 and the rewinding gear 10, causing the corresponding unwinding roller 5 and rewinding roller 6 to unwind and rewind synchronously, thus achieving the effect of changing the display surface of the prefix band, root band 7, and suffix band. Then, the positioning rod 13 is inserted into the corresponding positioning hole in the corresponding positioning plate 12, which can fix the lever 11 and thus fix the control gear 8, unwinding gear 9, and rewinding gear 10, preventing the prefix band, root band 7, and suffix band from becoming loose.
[0026] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
