DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Please refer to Figures 1-4 The oral support device for tooth correction in the embodiment comprises a main body 1, a bidirectional threaded rod 2 is rotationally connected inside the main body 1, two threaded sleeves 3 are threadedly connected outside the bidirectional threaded rod 2, two arc-shaped support plates 4 are arranged on the front side of the main body 1, and an auxiliary mechanism 5 is arranged between the arc-shaped support plates 4 and the main body 1.

[0025] Specifically, the auxiliary mechanism 5 comprises a support rod 501, the front side of the threaded sleeve 3 is connected with the support rod 501, the front side of the support rod 501 is hinged with a mounting plate 502, a connecting seat 503 is arranged between the two mounting plates 502, the upper and lower ends of the connecting seat 503 are hinged with adjusting rods 504, the side away from the connecting seat 503 of the adjusting rod 504 is provided with an adjusting groove 505, the inside of the adjusting groove 505 is mounted with a telescopic spring 506, one end of the telescopic spring 506 is connected with a moving rod 507, the left and right ends of the connecting seat 503 are fixedly mounted with L-shaped connecting rods 508, a cross rod 509 is mounted between the two L-shaped connecting rods 508, the rear side of the main body 1 is fixedly mounted with a mounting frame 510, the mounting frame 510 is slidingly connected with a push rod 511, the outside of the push rod 511 is sleeved with a reset spring 512, by arranging the telescopic spring 506, when the two arc-shaped supporting plates 4 move, the stretching and compression of the telescopic spring 506 can adapt to the movement of the arc-shaped supporting plates 4, and the size of most people's oral cavities does not differ greatly, so the spacing adjustment range between the two arc-shaped supporting plates 4 does not need to be adjusted too much, and the telescopic range of the telescopic spring 506 can adapt to the adjustment range; in addition, by pulling the push rod 511 outward, the L-shaped connecting rod 508 will be driven to move towards the main body 1, when the connecting seat 503 translates, the two adjusting rods 504 rotate, thereby driving the angle of the moving rod 507 to incline, so that the mounting plate 502 and the arc-shaped supporting plate 4 can be driven to incline to a certain extent, and the telescopic spring 506 can be extruded in the process of inclining, so that the oral cavity of the patient can be prevented from being further expanded, and then the arc-shaped supporting plate 4 can be smoothly taken off the teeth.

[0026] Specifically, the adjacent side walls of the two mounting plates 502 are provided with arc-shaped sliding grooves, and arc-shaped sliding blocks are slidingly connected in the arc-shaped sliding grooves, when the arc-shaped supporting plate 4 inclines to a certain extent, the arc-shaped sliding blocks will move in the arc-shaped sliding grooves to adapt to the movement of the arc-shaped supporting plate 4.

[0027] In implementation, the following steps are performed:

[0028] 1) first, the mouth of the patient is opened, and the two arc-shaped supporting plates 4 are placed between the teeth of the patient, then the rotating handle is rotated to drive the two arc-shaped supporting plates 4 to approach the teeth of the patient and support the oral cavity;

[0029] 2) then, if the patient needs to spit out saliva during the supporting process, the doctor only needs to pull the push plate 6 outward to incline the two arc-shaped supporting plates 4, at this time, the inner side of the teeth of the patient is separated from the limiting of the arc-shaped supporting plate 4, and then the support device can be taken off;

[0030] 3) finally, when installing, the push plate 6 is also pulled outward, the arc-shaped supporting plate 4 is aligned with the teeth of the patient, then the arc-shaped supporting plate 4 is slowly loosened to rotate, and finally the teeth of the patient are clamped again.

[0031] In summary, the oral cavity support device for tooth correction, by setting the auxiliary mechanism 5, only need to use the device first by using the two-way threaded rod 2 two arc-shaped support plate 4 according to the size of the patient's mouth adjusted to the appropriate spacing, if the patient needs to spit mouth during the support process, the doctor only need to pull the push plate 6 outside to make two arc-shaped support plate 4 tilt, so as to facilitate the patient's teeth from the arc-shaped support plate 4 off, installation, same reason, the doctor only need to push and pull the push plate 6, convenient and fast operation, reduces the treatment time of the patient, improves the treatment efficiency, solves the problem of the comparative device in the installation and removal of the support device is inconvenient to operate.
