[0026] The inner side of the body 100 has a spherical cavity 130, which has a diameter slightly larger than that of the elastic ball 300, and the elastic ball 300 is arranged in the spherical cavity 130. This facilitates the placement of the elastic ball 300, avoids the sliding of the elastic ball 300 in the body 100 during biting, and achieves the purpose of exercise. The elastic ball 300 supports the body 100, ensures that the body 100 has elasticity, and can restore deformation, and facilitates the exercise of the masseter muscle.

[0027] The two sides of the body 100 are provided with a fixing buckle 140, which is arranged close to the second face 102 to prevent the fixing buckle 140 from hindering the entry of the body into the oral cavity. The fixing buckle 140 includes a connecting part 141 and a buckle body 142, one end of the connecting part 141 is fixed on the inclined surface on both sides of the body 100, the other end of the connecting part 141 is fixed concentrically on the buckle body 142, the connecting part 141 is cylindrical, the diameter of the connecting part 141 is smaller than that of the buckle body 142, and the fixing band 200 is provided with a corresponding buckle hole 210. The fixing band 200 is fixed to the body 100 through the fixing buckle 140. This facilitates the fixed connection of the fixing band 200 and the body 100, and the fixing band 200 is fixedly connected in a detachable manner, which is convenient to use. Different lengths of fixing bands can be selected according to different head circumferences, and are suitable for patients with different head circumferences.

[0028] The fixing band 200 has two, respectively first fixing band 201 and second fixing band 202, first fixing band 201 and second fixing band 202 are close to one end of the body 100 respectively equipped with the buckle hole 210, the first fixing band 201 is equipped with the button 220 away from one end of the body 100, the second fixing band 202 is equipped with the fixed buckle hole 230 away from one end of the body 100, the button 220 is at least one, the button 220 is along the length direction of the first fixing band 201 is arranged, the fixed buckle hole 230 is at least three, the fixed buckle hole 230 is along the length direction of the second fixing band 202 is arranged.In use, the length of the fixing band 200 can be adjusted according to the size of the head circumference, which is convenient to fix on the head of the patient, frees the hands, improves the adaptability of the device, and the button fixing method is simple and fast, easy to use.

[0029] The first face 101 and the second face 102 are square, the side length of the first face 101 is 0.5cm-1cm, the side length of the second face 102 is 5cm-6cm, the distance between the first face 101 and the second face 102 is 6.5cm-7.5cm, the body 100 is larger, which ensures that the area of the bite is large during the bite exercise, not only the incisors are used for biting, but also the two sides of the canine teeth are used for biting, which ensures the force of the bite exercise and achieves the purpose of masseter muscle exercise and restores the masticatory function. The length of the fixing band 200 is 45cm-60cm. The fixing band can meet the needs of different head circumferences and is convenient to use.
