Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 and give, including left right direction and the fixed box 1 that the opening is right, upper and lower both sides in the fixed box 1 articulate respectively has the bracing piece 2 of V-arrangement, the opening of two bracing pieces 2 is relative and can be relative or swing back to back mutually, axial and opening arc 4 to the right side about the connecting plate 3 of bracing piece 2 is equipped with through left right direction's connecting plate, arc 4 is located fixed box 1 right-hand, fixed box 1's right side is equipped with limiting plate 5 that can reciprocate, limiting plate 5's lower terminal surface can with the upper surface contact of connecting plate 3.

In order to enable the two support rods 2 to swing oppositely or back to back, a sliding plate 6 which can move left and right and is in the vertical direction is arranged in the fixed box 1, and the upper end and the lower end of the sliding plate 6 are respectively hinged with the free ends of the support rods 2 on the corresponding sides through connecting rods 7.

In order to enable the sliding plate 6 to move left and right, a push rod 8 is arranged at the left end of the sliding plate 6, a push plate 9 is arranged at the left end of the push rod 8 and penetrates through the fixed box 1, and a spring 10 positioned between the sliding plate 6 and the fixed box 1 is sleeved on the push rod 8.

In order to facilitate pushing the push plate 9, the front end and the rear end of the fixed box 1 are respectively provided with a baffle plate 11.

In order to move the limiting plate 5 up and down, the limiting plate 5 is rotatably connected with a screw 12 in the vertical axial direction, the upper end of the screw 12 penetrates through the fixing box 1 and is in threaded connection with the fixing box 1, and the upper end of the screw 12 is provided with a knob 13.

In order to observe the opening distance of the oral cavity of the patient conveniently, the right end of the limiting plate 5 is provided with a pointer 14, and the right end face of the fixed box 1 is provided with scale marks 15.

In order to improve the comfort of the patient, a fixing belt 16 is arranged between the front end and the rear end of the fixing box 1.

When the utility model is used, the initial state of the device is that the opposite surfaces of the two arc-shaped plates 4 are contacted, the reading of the scale mark 15 corresponding to the pointer 14 is zero, and the reading of the scale mark 15 is increased from bottom to top;

inquiring the maximum distance that the mouth of the patient can be opened, taking out the device, rotating the knob 13 clockwise, the knob 13 driving the screw 12 to rotate clockwise, the screw 12 driving the pointer 14 to move upwards through the limiting plate 5, and simultaneously, observing the reading of the scale mark 15 corresponding to the pointer 14, for example: when the reading of the scale mark 15 corresponding to the pointer 14 is "5", the distance between the two arc-shaped plates 4 is 5mm, and when the reading of the scale corresponding to the pointer 14 is consistent with the maximum distance that the oral cavity of the patient can be opened, the knob 13 stops rotating, and due to the self-locking property of the screw 12, the pointer 14 cannot be driven to move by pushing the limiting plate 5;

the arc-shaped plate 4 is stuffed into the mouth of a patient, the arc-shaped plate 4 is positioned between the upper teeth and the lower teeth of the patient, the fixing belt 16 is pulled, the device is fixed on the head of the patient, the push plate 9 is pushed rightwards, the push plate 9 drives the slide plate 6 to move rightwards through the push rod 8 and stretches the spring 10, the slide plate 6 drives the left ends of the two support rods 2 to swing oppositely through the connecting rod 7, the right ends of the two support rods 2 drive the connecting plate 3 to swing oppositely and synchronously, and the two arc-shaped plates 4 move oppositely and drive the mouth;

when the connecting plate 3 on the upper side of the patient contacts the limiting plate 5, the two connecting plates 3 cannot continuously swing back to back, the oral cavity of the patient is opened to the maximum distance capable of being opened, the push plate 9 is loosened, the push plate 9 is driven by the sliding plate 6 through the push rod 8 to move left under the action of the spring 10, the sliding plate 6 drives the left ends of the two support rods 2 to swing back through the connecting rod 7, the right ends of the two connecting plates 3 drive the connecting plates 3 to synchronously swing oppositely, meanwhile, the connecting plate 3 on the upper side is separated from the limiting plate 5, the distance between the two arc-shaped plates 4 is reduced, and the oral cavity of;

after two arc 4 contacts, this device resumes initial condition, and above-mentioned motion is repeated, constantly makes patient's oral cavity open, close, tempers the ability of opening and shutting of patient's oral cavity.
