[0017] The terms "utility model" and "the present utility model" used in this specification are intended to refer broadly to all subject matter of this specification and any patent claims below. Statements containing these terms should not be understood to limit the subject matter described herein or to limit the meaning or scope of any patent claim below. In addition, this specification does not attempt to describe or limit the subject matter covered by any claim of any specific component, paragraph, statement or figure of this application. The subject matter should be understood with reference to the entire specification, all drawings and any claims below. The present utility model may have other embodiments and be practiced or implemented in other ways. Moreover, it should be understood that the wording and terminology used herein are for illustrative purposes and should not be considered as limiting.

[0018] The details of the present invention will now be discussed with reference to the accompanying drawings which illustrate the present invention by way of example only. In the accompanying drawings, similar features or components may be marked with the same reference numerals.

[0019] The use of "including", "having" and "comprising" and variations thereof herein is meant to include the items listed thereafter and their equivalents and additional items. Although reference may be made to directions such as above, below, upward, downward, backward, bottom, top, front, back, etc. in describing the drawings, for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the present invention in any form. In addition, terms such as "first", "second", "third", etc. are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0020] See also Figure 1 As shown, the mouth opening measuring device of the utility model includes a measuring device body, and the measuring device body includes a base 1, the base 1 has a left end 2 and a right end 3, the left end 2 of the base 1 is provided with an angle measuring device 4 for measuring the mouth opening degree, and the right end 3 of the base 1 is provided with a distance measuring device 5 for measuring the distance between incisors.

[0021] In a preferred embodiment, the base 1 is in the shape of a long handle.

[0022] Furthermore, the angle measuring device 4 includes a rotating indicator 6 and a scale display 7, the rotating indicator 6 has a rotating connection portion and an indicating portion, the rotating indicator 6 is rotatably connected to the front of the left end portion 2 of the base 1 through the rotating connection portion, the scale display 7 is located in the middle area of ​​the base 1, and an arc-shaped scale 8 is provided on the front of the scale display 7. The arc-shaped scale 8 is distributed with the rotation axis of the rotating connection portion of the rotating indicator 6 as the center of the circle. When the measuring angle is less than 90°, the indicating portion of the rotating indicator 6 points to the arc-shaped scale 8 of the scale display 7.

[0023] Specifically, the rotating indicator 6 is in the shape of a long handle, and the scale display 7 is in the shape of an arc strip. In this way, a hollow is formed between the scale display 7, the rotating indicator 6 and the base 1, which makes it more convenient to observe the lip shape.

[0024] The distance measuring device 5 is a ruler, the bottom of which is rotatably connected to the back of the right end 3 of the base 1, and the front of the ruler has a scale indication and a corresponding color prompt. Specifically, the distance is 0-6cm, and the smallest scale unit is 0.5cm, of which 0-0.5cm is filled with red, 0.5-1cm is orange, 1-2cm is filled with yellow, 2-3cm is filled with green, and above 3cm is filled with blue. The ruler and the rotating indicator 6 are respectively located on the front and back of the base 1, so that it can be folded and convenient to carry.

[0025] It is easy to understand that the rotating indicator 6 and the distance measuring device 5 both need to be temporarily stopped after rotation. The stopping method can be temporary pressing by hand or increasing the rotational friction. Increasing the rotational friction can be achieved by using rough surfaces in contact with each other, which belongs to the prior art.

[0026] Reinforcement plates (not shown in the figure) are respectively provided on the front and back surfaces of the rotation axis at both ends of the base 1.

[0027] The main body of the measuring instrument is made of soft magnetic material, which is convenient for temporary adsorption to a fixed place when idle. The reinforcement plate is made of plastic material, which can effectively reduce rotational wear, extend the service life of the product, and have low manufacturing cost.

[0028] When measuring the mouth opening, align the upper edge of the base 1 with the upper edge of the lower lip, push the rotating indicator 6 until the indicating center line of its indicating part is basically aligned with the lower edge of the upper lip, and read the indicating scale of the indicating part; when measuring the distance between the incisors, push the ruler to a vertical position, align the 0 scale with the upper edge of the lower incisors, and read the indicating scale and color zone of the lower edge of the upper incisors.

[0029] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
