It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0021] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides an oral opener with a dynamometer, including an instrument 1. A dynamometer box 2 is fixedly arranged on the surface of the instrument 1. Two springs 3 are symmetrically and fixedly arranged on an inner surface of the dynamometer box 2. One ends of the two springs 3 are fixedly connected with a moving plate 4, and the bottom of the moving plate 4 is fixedly arranged on the instrument 1. The instrument 1 includes a connecting member 101. Two pliers bodies 102 are symmetrically arranged on one side of the connecting member 101. Pressure plates 103 are fixedly arranged at one ends of the two pliers bodies 102 far away from the connecting member 101. One ends of the two pliers bodies 102 close to the connecting member 101 are rotatably connected to the connecting member 101 through pins. The dynamometer box 2 is fixedly arranged on the connecting member 101. A screw 104 is threadedly connected to the middle of the connecting member 101. One end of the screw 104 is rotatably connected with a circular plate 105 through a bearing, and the other end is fixedly connected with an operation plate 106.

[0022] The effect achieved by the entire Embodiment 1 is that the opening of the pliers body 102 is relatively small, and a pressing plate 103 is fixed, which can contact the patient's teeth. The operating plate 106 facilitates the medical staff to smoothly rotate the screw 104. Under the cooperation of the threads, the screw 104 drives the movement of the round plate 105 to drive the opening and closing of the pliers body 102, so as to apply pressure on the upper and lower jaws through the upper and lower teeth to achieve the purpose of opening the mouth. When using the instrument 1 for mouth opening training, the moving plate 4 will move correspondingly as the pliers body 102 opens, stretching the spring 3. The moving distance of the moving plate 4 can correspond to the corresponding force value, so as to reflect the corresponding value of the force applied by the mouth opener to the oral cavity. And rubber sleeves are sleeved and fixed on the surface of the pressing plate 103 and the end surface of the pliers body 102 close to the pressing plate 103 to soften the hardness of the part of the pliers body 102 entering the oral cavity.

[0023] Embodiment 2 is as follows Figures 1 - 4 As shown, the difference between this embodiment and Embodiment 1 is only that one end of each of the two pliers bodies 102 close to the connecting member 101 is slidably connected with a round rod 107 through a support plate. Ear blocks 108 are sleeved on the surfaces of the round rods 107, and the two ear blocks 108 are both fixed on the round plate 105; a connecting rod 109 is fixed on the surface of the round plate 105. The top of the connecting rod 109 sequentially penetrates through the top of the connecting member 101 and the bottom of the force measuring box 2 and is fixed to the bottom of the moving plate 4; a threaded hole 110 adapted to the screw 104 is provided in the middle of the connecting member 101, and an avoidance groove 111 adapted to the round plate 105 and the connecting rod 109 is provided at one end of the threaded hole 110 close to the round plate 105; a strip-shaped through port 5 adapted to the connecting rod 109 is provided at the bottom of the force measuring box 2, and the connecting rod 109 is slidably connected in the strip-shaped through port 5; the force measuring box 2 is a transparent box body, and a force value scale line 6 is provided at its top.

[0024] The effect achieved by the entire Embodiment 2 is that under the connection action of the connecting rod 109, when the screw 104 drives the round plate 105 to move, the moving plate 4 can be driven to move correspondingly in the force measuring box 2. Through the transparent force measuring box 2, the corresponding mouth opening force value can be obtained by referring to the force value scale line 6. The avoidance groove 111 is for the round plate 105 to be smoothly hidden in the connecting member 101 when the pliers bodies 102 are closed, so that the two pliers bodies 102 can be closed to a close state, so that the insertion end of the pliers body 102 is the smallest and it is convenient to insert into the patient's oral cavity.

[0025] Working principle: When in use, medical staff first place the thinnest end of the pliers body 102 between the upper and lower teeth of the patient, and rotate the pliers body 102 so that the two pressing plates 103 can be clamped on the upper and lower teeth. At this time, the two pressing plates 103 are respectively in contact with the upper and lower teeth of the patient. After placement, the medical staff rotate the operation plate 106, which can drive the screw rod 104 to rotate. Since the round rod 107 and the ear block 108 can limit the round plate 105, the round plate 105 will not be driven by the screw rod 104, but will move in cooperation with the movement of the screw rod 104. With the cooperation of the movement of the round plate 105 and the round rod 107 sliding on the pliers body 102, the other ends of the two pliers bodies 102 can be opened. Under the action of the connecting rod 109, the round plate 105 can drive the moving plate 4 in the force measuring box 2 to move correspondingly. Thus, pressure can be applied to the upper jaw and the lower jaw through the pressing plates 103 to achieve the purpose of opening the mouth. And while applying pressure, through the transparent force measuring box 2, the applied force value can be directly viewed by comparing with the force value scale line 6.

[0026] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
