[0033] like Figure 1 As shown in the figure, as a preferred embodiment, based on the above method, further, the inner side walls of the upper support plate 1 and the lower support plate 2 are inlaid with mutually cooperating magnets 8. It should be noted that, through the provision of the magnets 8, the upper support plate 1 and the lower support plate 2 are attracted to each other when they are folded together, thereby fixing the upper support plate 1 and the lower support plate 2 together.

[0034] like Figure 1 and Figure 3 As shown in the figure, as a preferred embodiment, based on the above-mentioned method, further, the back of the upper support plate 1 and the lower support plate 2 are provided with a plurality of evenly distributed connecting pieces 3, and the storage grooves 7 are used to store the elastic pieces 4. It should be noted that the provision of the storage grooves 7 makes it convenient to insert the disassembled elastic pieces 4 into the interior, thereby facilitating the storage of the elastic pieces 4 and preventing the elastic pieces 4 from being lost.

After each exercise, the length of the limit rope 501 can be gradually increased to improve the patient's exercise effect. At the same time, the first limit screw 502 and the second limit screw 503 can also limit the elastic sheet 4 installed inside the slide groove 104 to prevent the elastic sheet 4 from falling out from the inside of the slide groove 104.

[0038] Specifically, the working principle of the adjustable oral exerciser for nasopharyngeal carcinoma radiotherapy is as follows: when in use, the upper support plate 1 and the lower support plate 2 are opened, and then an appropriate number of elastic sheets 4 are selected according to the patient's own exercise needs and installed into the inside of the slide groove 104, and at this time, the upper support plate 1 and the lower support plate 2 are pressed inward at the same time, and the first limiting screw 502 and the second limiting screw 503 are respectively screwed into the limiting holes 105 on the upper support plate 1 and the lower support plate 2, thereby limiting the opening angle of the upper support plate 1 and the lower support plate 2, and at the same time, the length of the limiting rope 501 needs to be adjusted according to the degree to which the patient's mouth can be opened. After the assembly is completed, the upper support plate 1 and the lower support plate 2 are pressed to send them into the patient's mouth, so that the patient's upper and lower rows of teeth bite on the anti-slip gasket 6, and at this time, the elastic sheet 4 will open the upper support plate 1 and the lower support plate 2 under the action of its own elastic force, thereby opening the patient's mouth, and at the same time, the patient can squeeze the upper support plate 1 and the lower support plate 2 through his teeth. The elastic sheet 4 between the upper support plate 1 and the lower support plate 2 is used for bite training. Since the support plate 1 and the lower support plate 2 are completely inside the patient's mouth, the patient can also close the mouth with his lips during the training process to prevent saliva from flowing out. When not in use, the elastic sheet 4 between the upper support plate 1 and the lower support plate 2 is removed from the slide groove 104, and then the first limit screw 502 and the second limit screw 503 are unscrewed from the inside of the limit hole 105. At this time, the upper support plate 1 and the lower support plate 2 can be fully unfolded and thoroughly cleaned and disinfected. When carrying it out, the upper support plate 1 and the lower support plate 2 can be folded together, and the upper support plate 1 and the lower support plate 2 are adsorbed by the magnet 8, and then the elastic sheet 4 is inserted into the storage slot 7 for storage. The limit rope 501, the first limit screw 502 and the second limit screw 503 can be placed in the slide groove 104, thereby completing the storage of the oral exerciser. After storage, its body is in the form of a card, which can be conveniently carried.
