During the movement of the two mounting blocks 302 under force, the sliding guiding action of the sliding groove 901 and the sliding bar 902 causes the two mounting blocks 302 to move closer to or away from each other after being subjected to force. During the movement of the two mounting blocks 302, the arc support plate 303 is pulled to move toward or away from the mounting sleeve 2 under force through the connection transmission action of each component on the elastic component 4, and the use position of each arc support plate 303 is adjusted. By adjusting the use position of each arc support plate 303, the entire mouthpiece can be placed in the oral cavity of different users for support and fixation.

[0025] Preferably, the driving component 11 includes a connecting shaft 1101 rotatably connected to one end of the mounting sleeve 2, one end of the connecting shaft 1101 is fixed to one end of the double-headed screw rod 1001, a second gear 1102 is fixed to one end of the connecting shaft 1101, and a ring gear 1103 is connected to the outer side of the mounting sleeve 2 through the mounting component 12, and the ring gear 1103 and the second gear 1102 are meshed with each other; the ring gear 1103 is rotated, and during the rotation of the ring gear 1103, the mutual meshing transmission between the ring gear 1103 and the second gear 1102 drives each connecting shaft 1101 to rotate, and during the rotation of the connecting shaft 1101, the double-headed screw rod 1001 is driven to rotate.

[0026] Preferably, the mounting assembly 12 includes an annular groove 1201 opened on the inner side of the gear ring 1103, and an annular plate 1202 is rotatably connected to the annular groove 1201, and the annular plate 1202 is fixed to the outer side of the mounting sleeve 2; through the annular plate 1202 and the annular groove 1201, the gear ring 1103 can be rotatably connected to the outer side of the mounting sleeve 2.

[0027] Working principle: During the non-painless gastroscopy, a mouthpiece is used to fix the user's mouth. Before the mouthpiece is used to fix the user's mouth, the support position of each arc-shaped support plate 303 is adjusted according to the diameter of the inner side of the user's mouth. During the adjustment process, the ring gear 1103 is rotated. During the rotation of the ring gear 1103, the mutual meshing transmission between the ring gear 1103 and the second gear 1102 drives each connecting shaft 1101 to rotate. During the rotation of the connecting shaft 1101, the double-headed screw rod 1001 is driven to rotate. Because the threads at both ends of the double-headed screw rod 1001 are arranged in opposite directions, during the rotation of the double-headed screw rod 1001, the two threads are engaged with each other. The sleeves 1002 are respectively meshed with the two ends of the double-headed screw rod 1001 to drive the two mounting blocks 302 to move under force. During the movement of the two mounting blocks 302 under force, the sliding guide action of the sliding groove 901 and the sliding bar 902 causes the two mounting blocks 302 to move closer to or away from each other after being subjected to force. During the movement of the two mounting blocks 302, the arc-shaped support plate 303 is pulled to move toward or away from the mounting sleeve 2 through the connection and transmission action of each component on the elastic component 4, and the use position of each arc-shaped support plate 303 is adjusted. By adjusting the use position of each arc-shaped support plate 303, the entire mouthpiece can be placed in the oral cavity of different users for support and fixation. After the use position adjustment of each arc support plate 303 is completed, the mouthpiece is inserted into the user's oral cavity. During the insertion process, the upper teeth of the user's upper and lower oral cavity are abutted against the arc support plate 303, and the inside of the user's oral cavity is supported by each arc support plate 303, which plays the effect of fixing the user's mouth during non-painless gastroscopy. During the non-painless gastroscopy, when the user bites nervously, the arc support plate 303 is pushed to move toward the installation sleeve 2 through the bite action. During the movement of the arc support plate 303, the transmission rod 403 pushes the slide plate 402 to slide inside the installation cylinder 401. During the sliding process, the slide plate 402 squeezes the first spring 404 to generate elastic force. The elastic force of the first spring 404 is used to elastically support the arc support plate 303 that moves after being stressed. The elastic support alleviates the stress movement of the arc support plate 303 during the bite process, thereby reducing the probability of the gastroscope being bitten / damaged clinically. In the process of pushing the arc support plate 303 toward the installation sleeve 2 through the patient's bite, the push plate 701 is driven to move synchronously with the movement of the arc support plate 303. During the movement of the push plate 701, the interaction between the inclined groove 702 and the transmission pin 703 drives the rack 602 to move under force. During the movement of the rack 602, the rack 602 is forced to move horizontally on one side of the arc support plate 303 through the sliding guide effect of each sleeve 803 and the slide rod 804 on the connecting component 8. The rotating shaft 502 is driven to rotate through the mutual meshing transmission between the rack 602 and the first gear 601. During the rotation of the rotating shaft 502, the rubber protrusions 504 on the driving disk 503 are driven to contact the arc support plate 303 in turn, and the arc support plate 303 is intermittently knocked. The arc support plate 303 and the teeth that contact with each other vibrate through the knocking action. Through the vibration action, the patient in the process of tense biting is warned not to continue to bite hard, thereby further reducing the probability of the gastroscope being bitten / damaged in clinical practice.
