Through the structures of the first connecting rod 111 and the second connecting rod 112 and the hinge structures of the side supports 101 and the second side support plates 107, the position of the V-shaped soft pad 114 and the position of the U-shaped inner support arms 3 can be correspondingly adjusted to adapt to the oral cavity shape and bone structure of a person. After installation, the rotating sleeve 109 can be reversely rotated according to the oral cavity position being processed at this time. Under the limiting action of the connecting structure between the limiting sleeve 106 and the inner support rod 103, the distance between the first support rod 110 and the screw rod 108 is reduced, so as to relax the oral cavity on the other side, avoid tearing of the corners of the mouth caused by excessive time of fully opening the oral cavity, effectively protect the soft tissues, improve the comfort of the examination, and the setting of the first support 104 can establish the connection between the limiting sleeve 106 and the first support rod 110 through the interference movement of the first support rod 110 in the arc-shaped groove 105, so as to provide a certain supporting force for each other, avoid the generation of deformation, and ensure the service life.

[0042] Referring to Figure 3 , in a preferred embodiment, a clamping groove 117 is provided on the inner wall of the rotating sleeve 109. Clamping rings 118 are symmetrically and fixedly sleeved on the first support rod 110. Each clamping ring 118 is correspondingly rotatably clamped in the clamping groove 117. A plurality of first convex strips 115 are equidistantly arranged on the outer side of the rotating sleeve 109.

In the connecting mechanism 2, when the U-shaped support frame 202 on the U-shaped inner support arm 3 is inserted from the notch 205 and attached to one outer wall of the third bracket 209, the bottom end of the abutting frame 201 abuts against one side of the square support plate 211 to provide a limit at the same time. Subsequently, by rotating the knob 210, the third bracket 209 and the arc-shaped limiting frame 206 can be driven to rotate, so that the arc-shaped limiting frame 206 is attached to the outer wall of the second bracket 203, and the friction between the arc-shaped limiting frame 206 and the second bracket 203 is increased by the arrangement of the second protrusions 204 and the third protrusions 207. Thus, through the limits of the arc-shaped limiting frame 206 and the abutting frame 201, the U-shaped inner support arm 3 can be stably installed on the side bracket 101, making the U-shaped inner support arm 3 detachable. Since the V-shaped soft pad 114 is connected to the V-shaped bottom frame 113 by the adhesion of the first magic tape 120 and the second magic tape 121, the disassembly of the V-shaped soft pad 114 is also convenient. Based on the disposable use of the V-shaped soft pad 114 and the U-shaped inner support arm 3, the use safety of the instrument can be guaranteed.

A first through groove 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 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 one side inner wall of the V-shaped inner bracket 410 is symmetrically fixedly connected to two cotton threads 407, 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 penetrated with a perforation 411, each cotton thread 1 407 is movably sleeved with a cotton sleeve 409, and the cotton sleeve 409 partially passes through the perforation 411, 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 tongue root, and the tongue bottom 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, and then connected to the connecting port 405 through an external suction machine, and the retained saliva can be sucked and discharged through the straw 404. During the process, the saliva can be filtered through the setting of the grid plate 414 to avoid saliva clogging. The suction tube 404 or the suction machine is plugged, 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 hygroscopic effect, it can prevent saliva 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 translated along the cotton thread 1 407 and pass through the perforation 411, so that the cotton sleeve 409 can be separated from the oral cavity, and 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 the 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, which is convenient for pulling out the cotton sleeve 409, and also avoids the V-shaped inner bracket 410 from being installed incorrectly and causing throat jam. 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 comprises the following specific steps:

[0051] S1: Insert the two U-shaped inner support arms 3 into the corners of the mouth, and adjust the distance between the two U-shaped inner support arms 3 by rotating the rotating sleeve 109;

[0052] S2: adjusting 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, place the tongue root on the U-shaped cushion 401, and clamp the two elastic hooks 406 to the inner support rod 103 or the outside 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 this side. As the inspection position changes, the rotating 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 frame 113 by the shape of the V-shaped 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 hinged 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 arm 3 can be adjusted accordingly to adapt to the shape of the oral cavity and the bone structure of the person. After installation, it can be rotated in the opposite direction according to the position of the oral cavity being treated at that time. The rotating sleeve 109, under the limiting effect of the connection structure of 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 opened 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 through 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 occurrence of deformation, and ensuring the service life.
