[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The two ends of the second rotatable plate 1 are fixedly mounted on the outer ends of the two arc-shaped extension plates 1, and the two ends of the second rotatable plate 1 are fixedly mounted on the outer ends of the two arc-shaped extension plates 1.

[0024] Working principle: When in use, the arc-shaped expansion plate 1 is placed in the patient's oral cavity. According to the contour of the patient's oral cavity, the distance between the first rotating seat 21 and the second rotating seat 22 and the arc-shaped expansion plate 1 can be adjusted through the plug-in connection between the plug-in plate 32 and the plug-in sleeve 3. According to the size of the patient's oral cavity, the two arc-shaped expansion plates 1 can be expanded outward through the rotation connection between the first rotating seat 21 and the second rotating seat 22. The patient's oral cavity can be positioned by cooperating with the positioning groove 11. Then, the connection between the first rotating seat 21 and the second rotating seat 22 can be positioned by plugging the positioning gear rod 25 and the first positioning tooth hole 23 and the second positioning tooth hole 24. This can prevent the arc-shaped expansion plate 1 from loosening in the patient's oral cavity and ensure the positioning effect of the device on the patient's oral cavity.

[0025] Different saliva suction devices can be installed and positioned by means of the arc-shaped clamping plates 14 that are offset from each other on the upper and lower sides. The saliva suction devices can collect saliva and blood secreted from the patient's mouth, thereby maintaining the patient's oral hygiene and ensuring the health and safety of the patient and medical staff.

[0026] As a further description of the above technical solution: a threaded curved groove 26 is opened on the periphery of the positioning gear rod 25 , and a threaded ring 27 threadedly connected to the threaded curved groove 26 is rotatably installed at the front end of the second rotating seat 22 .

[0027] Specifically, at the front end of the second rotating seat 22, the threaded ring 27 is rotated, and the first positioning tooth hole 23 is plugged into the positioning gear rod 25 to restrict the movement direction of the positioning gear rod 25. The rotating threaded ring 27 can drive the positioning gear rod 25 to move through the threaded connection between the threaded ring 27 and the threaded curved groove 26, so that the positioning gear rod 25 is plugged into the first positioning tooth hole 23 and the second positioning tooth hole 24, thereby achieving the positioning effect of the rotating connection between the first connecting seat 12 and the second connecting seat 13.

[0028] As the further description of the above technical scheme: the plug sleeve 3 is provided with a plug cavity 31, the plug plate 32 is plug-connected and installed in the plug cavity 31, the plug cavity 31 is provided with a positioning tooth groove 33 on both sides of the inner cavity, the plug plate 32 is provided with a positioning tooth block 34 which is plug-connected with the positioning tooth groove 33 and is slidingly installed on both sides of the plug plate 32; the plug plate 32 is provided with a movable cavity 341, the movable cavity 341 is provided with a limiting cavity 342 on both upper and lower sides, the positioning tooth block 34 is slidingly installed in the limiting cavity 342, and the limiting cavity 342 is fixedly provided with a limiting clamping plate 343 which is clamped with the limiting cavity 342; the inner side of the positioning tooth block 34 is fixedly provided with a sliding rod 353 through a connecting plate 352, the movable cavity 341 is rotatably provided with a rotating disc 35, the rotating disc 35 is provided with a sliding cavity 351 which is slidingly connected with the sliding rod 353, and the sliding cavity 351 is inclinedly arranged; the plug plate 32 is provided with a limiting rotating cavity 36 at the front end, the limiting rotating cavity 36 is rotatably provided with a rotating plate 363, the rotating plate 363 is fixedly connected with the rotating shaft of the rotating disc 35, the limiting rotating cavity 36 is fixedly provided with a first connecting block 361 on the periphery, the first connecting block 361 is fixedly provided with an arc-shaped limiting rod 362 between the first connecting block 361, the rotating plate 363 is fixedly provided with a second connecting block 364 which is slidingly connected with the arc-shaped limiting rod 362 on the periphery, and the second connecting block 364 is fixedly provided with a spring 365 which is sleeved on the periphery of the arc-shaped limiting rod 362 between the second connecting block 364 and the first connecting block 361.

[0029] Specifically, when the expansion length between the plug sleeve 3 and the plug plate 32 is adjusted, the rotating plate 363 is rotated in the limiting rotating cavity 36, the rotating disc 35 is rotated in the movable cavity 341, the positioning tooth block 34 is limited in the movement direction through the plug connection between the limiting cavity 342 and the positioning tooth block 34, and the rotating rotating disc 35 can drive the positioning tooth block 34 to shrink inwardly into the limiting cavity 342 through the sliding connection between the sliding cavity 351 and the sliding rod 353.

[0030] The expansion length of the plug sleeve 3 and the plug plate 32 is adjusted through the plug connection between the plug plate 32 and the plug cavity 31, then the rotating plate 363 is loosened, the rotating plate 363 and the rotating disc 35 are reversely rotated under the action of the spring 365 which restores the deformation, and then the positioning tooth block 34 is reversely expanded to be plug-connected with the positioning tooth groove 33, so that the connection between the plug sleeve 3 and the plug plate 32 can be positioned.
