[0047] Reference Figure 6 and Figure 7 In a preferred embodiment, the internal support mechanism 4 includes a V-shaped inner bracket 410, and a groove 2 413 is provided on the inner wall of the top end of the V-shaped inner bracket 410, and the groove 2 413 is filled with a U-shaped cushion 401, and a through groove 2 412 is provided through the center position of the groove 2 413 and the U-shaped cushion 401, and a through groove 1 402 is provided through one side of the V-shaped inner bracket 410.

[0048] Reference Figure 6 and Figure 7In a preferred embodiment, the inner wall of the through groove 402 is fixedly connected to a support plate 403, and the inner wall of the support plate 403 is fixedly connected to a suction pipe 404, one end of the suction pipe 404 is provided with a connecting port 405, and the connecting port 405 is connected to an external suction machine, the inner wall of the suction pipe 404 is fixedly connected to a grid plate 414, and two cotton threads 407 are symmetrically fixedly connected to the inner wall of one side of the V-shaped inner bracket 410, and one end of each cotton thread 407 is fixedly connected to an elastic hook 406.

[0049] Reference Figure 6 and Figure 7 In a preferred embodiment, one side of the V-shaped inner bracket 410 is symmetrically provided with a perforation 411, and each cotton thread 1 407 is movably sleeved with a cotton sleeve 409, and the cotton sleeve 409 partially passes through the perforation 411, and one side of the cotton sleeve 409 is connected to a cotton thread 2 408, and one end of the cotton thread 2 408 is twisted with the middle section of the cotton thread 1 407. In the inner support mechanism 4, the V-shaped inner bracket 410 can be placed in the oral cavity, located between the lower jaw and the root of the tongue, and the bottom of the tongue is attached to the U-shaped cushion 401. The tongue provides support, and based on the softness of the U-shaped cushion 401, the comfort of the tongue contact surface can be optimized. Based on the second groove 412 set at the center, when the tongue is lifted, the saliva secreted from the bottom can drip from the second groove 412 to the bottom of the V-shaped inner bracket 410, that is, it is retained between the lower jaw and the tongue root. After that, it is connected to the connecting port 405 through an external suction machine, and the retained saliva can be sucked out through the straw 404 and discharged. During the process, the saliva can be filtered by the setting of the grid 414 to avoid saliva clogging due to thick saliva. The straw 404 or the suction machine is plugged in, and based on the setting of the cotton thread 1 407 on both sides, wherein the cotton thread 1 407 is distributed on both sides between the lower jaw and the tongue root, and based on the fact that the cotton thread and the cotton sleeve 409 both have a moisture absorption function, saliva can be prevented from overflowing from both sides into the pharynx during the retention process, and based on the setting of the cotton thread 2 408, by pulling the cotton thread 2 408 outward, the cotton sleeve 409 can be moved horizontally along the cotton thread 1 407 and pass through the perforation 411, so that the cotton sleeve 409 can be separated from the inside of the oral cavity. Due to the different physical conditions of the human body, the tongue is stimulated. The amount of saliva secreted after the root is also different. Pulling out the cotton sleeve 409 can be used by people with small secretion, avoiding the cotton sleeve 409 from excessively absorbing saliva inside the mouth and causing discomfort, and has higher adaptability. The setting of the elastic hook 406 can be respectively connected to the inner support rod 103 and the limiting sleeve 106, and can support the cotton thread 407 to facilitate the pulling out of the cotton sleeve 409. At the same time, it also avoids the V-shaped inner bracket 410 from being stuck in the throat due to incorrect installation, and the V-shaped inner bracket 410 is limited by establishing a connection with the expansion mechanism 1.

[0050] Reference Figure 8 A method for using a mouth opening and shaping device for oral examination includes the following specific steps:

[0052] S2: Adjust the angle between the first connecting rod 111 and the second connecting rod 112 so that the V-shaped cushion 114 completely fits the chin;

[0053] S3: Insert the inner support mechanism 4 so that the tongue base is placed on the U-shaped cushion 401, and clamp the two elastic hooks 406 to the inner support rod 103 or the outer side of the limiting sleeve 106 respectively;

[0054] S4: Connect the external suction machine to the connection port 405;

[0055] S5: According to the inspection position, the rotating sleeve 109 on the other side is rotated in the opposite direction to relax the U-shaped inner support arm 3 on that side. As the inspection position changes, the rotation operation of the rotating sleeve 109 changes accordingly;

[0056] S6: If the amount of saliva secretion in the oral cavity is small, the cotton sleeve 409 is pulled out and separated from the oral cavity.

[0057] Working principle: When using the device, first fit the V-shaped cushion 114 to the chin, and relatively stabilize the position of the V-shaped base frame 113 by the shape of the V-shaped base frame 113 and the fit of the V-shaped cushion 114. Then, symmetrically support the two U-shaped inner support arms 3 at the corners of the mouth. Through the structure of the connecting rod 111 and the connecting rod 2 112 and the hinge structure of the side bracket 101 and the side support plate 2 107, the position of the V-shaped cushion 114 and the position of the U-shaped inner support arms 3 can be adjusted accordingly to adapt to the shape of the human oral cavity and bone structure. After installation, it can be rotated in the opposite direction according to the oral position being treated at that time. The rotating sleeve 109, under the limiting action of the connection structure between the limiting sleeve 106 and the inner support rod 103, shortens the distance between the support rod 110 and the screw 108, thereby relaxing the oral cavity on the other side, avoiding the mouth corners from being torn due to the oral cavity being fully open for too long, effectively protecting the soft tissue, and improving the comfort of the examination. The setting of the bracket 104 can establish the connection between the limiting sleeve 106 and the support rod 110 by the interference fit movement of the support rod 110 in the arc groove 105, thereby providing a certain supporting force to each other, avoiding the generation of deformation, and ensuring the service life.
