Referring to fig. 3-6, a liquid chamber 7 is disposed at a position on the left side of the deflection chamber 3 inside the force applying member 1, an extruding plate 8 is sealingly and slidably mounted in the liquid chamber 7 (the connection relationship is similar to the connection relationship between an oil cylinder and a piston in the prior art), an air bag 10 is fixedly mounted on the inner side surface of the force applying member 1, the air bag 10 is located at the right side of the hinge point of the two force applying members 1, a liquid guiding hole 11 is disposed at a position between the liquid chamber 7 and the air bag 10 inside the force applying member 1, the outer side of the liquid guiding hole 11 is communicated with a cavity at the inner side of the extruding plate 8 in the liquid chamber 7, the inner side of the liquid guiding hole 11 is communicated with an inner cavity of the air bag 10, a connecting rope 12 (such as a steel wire rope) is fixedly mounted on the inner side surface of the extruding plate 8, the other end of the connecting rope 12 extends into the deflection chamber 3 and forms a fixed connection with the inner side surface of the deflection member 4, and in the process that the deflection member 4 moves outward, will pull the stripper plate 8 to move inwards through the connecting rope 12, and then make the stripper plate 8 squeeze the medium in the fluid chamber 7 into the gasbag 10 through the drain hole 11, make the gasbag 10 in the inboard position of the force application part 1 expand, later, when the medical personnel holds the unstable force application part 1 and the patient closes the oral cavity automatically, the patient's teeth will drive two bracing pieces 2 to approach, and then make the gasbag 10 in the inboard position of two force application parts 1 squeeze each other, cause the medium in the gasbag 10 to exert the outside shifting force to the stripper plate 8, make the stripper plate 8 exert the inside shifting force to the deflection part 4 through the connecting rope 12, because at this moment, the patient's teeth stretch into the interval between bracing piece 2 and the force application part 1, make the deflection part 4 unable to drive the bracing piece 2 to reset through the connecting rod 6, through the above-mentioned action, and then utilize the gasbag 10 to limit the resetting of the force application part 1, therefore, the patient can not close the oral cavity, and the influence of the condition on the examination operation is further reduced through the action.

The inside lateral position that is located sap cavity 7 of application of force spare 1 has seted up the hole of disappointing 9, and the hole of disappointing 9 intercommunication external environment is with the cavity that is located 8 lateral positions in the sap cavity 7.

The cavity body positioned at the inner side of the extrusion plate 8 in the liquid cavity 7 and the inner cavity of the air bag 10 are filled with liquid medium (such as water), and the transmission stroke between the structures cannot be influenced by the gas compression amount through the arrangement of the liquid medium.

The cross-sectional area of the liquid cavity 7 is larger than that of the air bag 10, and rubber pads are arranged on the side faces, opposite to the force application part 1, of the support rod 2, so that the support rod 2 only needs to deflect by a small angle, and the air bag 10 can expand by a large volume.

Referring to fig. 3 and 4, a sealing member 13 is sealingly and slidably mounted at a position between the liquid chamber 7 and the deflection chamber 3 inside the force application member 1, the connection rope 12 is arranged in two segments, a left segment of the connection rope 12 connects an inner side surface of the extrusion plate 8 and a left side surface of the sealing member 13, and a right segment of the connection rope 12 connects a right side surface of the sealing member 13 and an inner side surface of the deflection member 4, and by the arrangement of the above structure, the liquid medium in the liquid chamber 7 is prevented from leaking, and the realization of the above functions is prevented from being affected.

The use method (working principle) of the invention is as follows:

when the medical care personnel works, firstly, the support rods 2 are extended into the oral cavity of a patient by the medical care personnel, then, the medical care personnel applies inward holding force to the annular ends of the two force applying parts 1, so that the two support rods 2 are mutually far away and the oral cavity of the patient is opened, in the process, the tail ends of the support rods 2 can contact the upper jaw and the tongue surface of the patient, as the tail ends of the support rods 2 are subjected to inward acting force applied by the upper jaw and the tongue surface, and the connecting ends of the support rods 2 and the force applying parts 1 are subjected to outward supporting force, so that the tail ends of the support rods 2 are deflected inwards, and the corresponding deflecting parts 4 are driven by the connecting rods 6 to move outwards, so that the deflecting parts 4 extrude the elastic parts 5 by the deflecting parts 4, meanwhile, the connecting ropes 12 and the sealing parts 13 are pulled by the deflecting parts 4 moving outwards, so that the extruding plates 8 move inwards, and part of media in the liquid cavities 7 are extruded into the air bags 10 through the liquid guide holes 11, the air bags 10 at the inner sides of the two force application pieces 1 are expanded, in the deflection process of the supporting rod 2, the gap between the supporting rod 2 and the force application piece 1 is increased, and then the teeth of a patient extend into the gap, and then in long-time examination operation, when medical staff unstably holds the force application piece 1 and the patient automatically closes the oral cavity, the teeth of the patient drive the two supporting rods 2 to approach, so that the air bags 10 at the inner sides of the two force application pieces 1 can extrude each other, a medium in the air bags 10 passes through the liquid guide holes 11, and the extrusion plates 8 are further driven to move outwards, so that the extrusion plates 8 apply inward moving force to the deflection pieces 4 through the connecting ropes 12, because at the moment, the teeth of the patient extend into the gap between the supporting rod 2 and the force application piece 1, the deflection pieces 4 cannot drive the supporting rod 2 to reset through the connecting rods 6, and through the actions, and then utilize gasbag 10 restriction application of force piece 1 to reset to make the unable closed oral cavity of patient, later, after the inspection finishes, make the patient still open the oral cavity, then, make medical personnel apply outside power to two application of force pieces 1, make bracing piece 2 inwards move, and then make patient's tooth break away from above-mentioned clearance, simultaneously, elastic component 5 release elasticity, and two application of force pieces 1 drive corresponding gasbag 10 and extrude each other, make above-mentioned structure position, finally, take out bracing piece 2, this is a duty cycle.
