Detailed Implementation

[0024] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Please see Figures 1 to 6 The present invention preferably provides the following technical solution: an auxiliary mouth opener, comprising: a first arc-shaped opening and a second arc-shaped opening; an adjusting handle disposed between the first arc-shaped opening and the second arc-shaped opening for adjusting the horizontal distance between the first arc-shaped opening and the second arc-shaped opening; the first arc-shaped opening and the second arc-shaped opening are symmetrically distributed and have the same structure; wherein, the first arc-shaped opening includes an arc-shaped strip 111, and a first extension and a second extension are installed on the upper and lower parts of the arc-shaped strip 111. When the first extension and the second extension work together with the first arc-shaped opening and the second arc-shaped opening to act at the junction of the upper and lower lips and the gums and form an internal support, it is convenient to expose the teeth and clean them.

[0026] This device is as follows Figure 1 ,2 As shown in Figures 1 and 3, the lower part of the symmetrical and identical first and second arc-shaped openings is provided with an adjustment handle for adjusting their horizontal spacing, so as to adapt to the differences in mouth opening of different people and expand the applicability of the device.

[0027] The arc-shaped strip 111, where the first and second arc-shaped openings are located, together with the first and second extensions respectively provided above and below it, can work together at the junction of the upper and lower lips and the gums to form internal support, as shown in the following state: Figure 6 As shown, this allows the teeth to be exposed for cleaning, which not only makes it easier for staff to clean the teeth but also improves the cleaning effect.

[0028] In addition, the structural design of the first and second extensions not only improves the comfort of the internal support, but also allows for adjustment of the degree of internal support according to the size of the user's mouth to meet different mouth opening needs.

[0029] Furthermore, the adjusting handle includes two support rods 118, one end of which is detachably mounted on the lower part of two arc-shaped bars 111, and the other end of which is respectively fixed with a handle rod 119 and a handle sleeve 120. The end of the handle rod 119 extends into the handle sleeve 120 and is provided with an elastic buckle structure 122; and a through hole 121 is opened on the handle sleeve 120 and adapted to engage with the elastic buckle structure 122. Furthermore, the elastic buckle structure 122 includes a vertical hole 1221 opened on the handle rod 119 near the end of the handle sleeve 120, and each vertical hole 1221 is provided with symmetrically distributed top posts 1222; and a spring 1223 connected between the two top posts 1222.

[0030] like Figure 4 , 5 As shown, one end of each of the two support rods 118 is fitted to the lower part of the two arc-shaped bars 111, while the other end is fixed with a handle 119 and a handle sleeve 120 respectively. The handle 119 extends into the handle sleeve 120 and is provided with an elastic buckle structure 122 that is adapted to engage with the through hole 121. Therefore, when the elastic buckle structure 122 is operated so that it enters the appropriate through hole 121, the horizontal distance between the two arc-shaped bars 111 can be adjusted.

[0031] Specific examples Figure 4 As shown, when it is necessary to adjust the horizontal distance between the two arc-shaped bars 111, first press the two top posts 1222, then compress the springs 1223 and 1223. Then pull the handle 119 and the handle sleeve 120 to adjust the horizontal distance between the two arc-shaped bars 111. When the two arc-shaped bars 111 are adjusted to a suitable distance, release the pressure on the top posts 1222. Then the two top posts 1222 can adapt to enter the corresponding through holes 121 to realize the adjustment process of the distance between the two arc-shaped bars 111.

[0032] Furthermore, each support rod 118 is provided with an assembly between it and its corresponding arc-shaped strip 111 for detachable assembly of the support rod 118 and the arc-shaped strip 111. The assembly includes screw holes 215 and mating grooves 214 distributed inside and outside the lower part of the arc-shaped strip 111; and a mating sleeve 211 fixed to the end of the support rod 118 and limited by the mating groove 214. The mating sleeve 211 has an assembly hole 213 in the middle. It also includes a bolt 212. When the bolt 212 passes through the assembly hole 213 and is threadedly connected to the screw hole 215, it is used for detachable installation of the support rod 118 and the arc-shaped strip 111 to facilitate the disassembly and cleaning process of each structure.

[0033] like Figure 4 , 5 As shown, the lower part of the arc-shaped strip 111 is provided with screw holes 215 and mating grooves 214 distributed internally and externally, while the end of the support rod 118 is provided with assembly holes 213 and mating sleeves 211 distributed internally and externally. When the bolt 212 passes through the assembly hole 213 and is threadedly connected to the screw hole 215, the horizontal displacement of the two arc-shaped strips 111 can be locked, and vice versa, the two can be unlocked.

[0034] Furthermore, the first extension includes a first limiting groove 112 formed on the inner wall of the top of the arc-shaped strip 111, a first limiting plate 113 slidably mounted with the first limiting groove 112, and a first support pad 114 detachably mounted on the top of the first limiting plate 113; further, the second extension includes a second limiting groove 115 formed on the inner wall of the bottom of the arc-shaped strip 111, a second limiting plate 116 slidably mounted with the second limiting groove 115, and a second support pad 117 detachably mounted on the bottom of the second limiting plate 116.

[0035] The first extension and the second extension have similar structures. When the first limiting plate 113 and the second limiting plate 116 are pulled out so that the first support pad 114 and the second support pad 117 extend toward the center, the first extension and the second extension can expand the support surface, thereby satisfying the flexible adjustment of different oral cavity support surfaces.

[0036] It is worth noting that the first support pad 114 and the second support pad 117 are detachable and can be easily replaced with first support pad 114 and second support pad 117 of different thicknesses, so as to adjust the degree of internal support according to the user's oral cavity.

[0037] Furthermore, the inclination of the first support pad 114 increases gradually from the inside out, such as... Figure 6 As shown, this is to accommodate the support needs of the upper and lower lips when the mouth is open.

[0038] Furthermore, a medical rubber pad is provided on the inner side of each arc-shaped strip 111; the first support pad 114 and the second limiting plate 116 are both made of medical rubber material to improve comfort while ensuring safety.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0040] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
