Detailed Description

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

Given by fig. 1 to 4, including the flat board 1 of left right direction, but the flat board 1 left and right sides is equipped with horizontal slip's slider 2 respectively, two sliders 2 keep the reverse slip, every 2 upper ends of slider all articulate through connecting block 3 has connecting rod 4, two connecting rod 4 upper ends articulate has the U-shaped pole 5 of left right direction, the axial sliding shaft 6 is controlled to the 5 left and right sides of U-shaped pole sliding connection respectively, the looks remote site of two sliding shaft 6 is equipped with connecting plate 7 of upper and lower direction respectively, the cover is equipped with the spring 8 that is located between U-shaped pole 5 and connecting plate 7 respectively on two sliding shaft 6 outer fringe faces, two connecting plate 7 lower extremes are equipped with arc layer board 9 respectively, the intrados of two arc layer boards 9 are relative.

In order to enable the two sliding blocks 2 to slide left and right, the left side and the right side of the flat plate 1 are respectively provided with a support plate 10 which is arranged in the vertical direction and is positioned outside the two sliding blocks 2, a screw rod 11 in the left-right axial direction is rotatably connected between the two support plates 10, the screw thread rotating directions of the left side and the right side of the screw rod 11 are opposite, and the screw thread rotating directions of the left side and the right side of the screw.

In order to rotate the screw rod 11 conveniently, the right end of the screw rod 11 penetrates through the right supporting plate 10 and is coaxially provided with a rotary disc 12, and the right end of the rotary disc 12 is provided with a left-right axial handle 13.

In order to make the device more stable when in use, the left and right sides of the front and back ends of the flat plate 1 are respectively provided with an outward inclined supporting leg 14.

In order to prevent the sliding shafts 6 from separating from the U-shaped rod 5, cylindrical stoppers 15 are coaxially arranged on the two sliding shafts 6 at the left and right sides of the U-shaped rod 5, respectively.

For better use effect, the two arc-shaped supporting plates 9 are both provided with rubber pads.

When the utility model is used, firstly, the device is placed at the front side of a patient, the flat plate 1 is kept horizontal, then the connecting plates 7 at the two sides are simultaneously pulled outwards by both hands, the flat plates 1 at the two sides respectively drive the sliding shafts 6 corresponding to the flat plates to slide outwards, the springs 8 are simultaneously compressed outwards, the distance between the two connecting plates 7 is gradually increased, and when the distance between the two connecting plates 7 is larger than the width of the lower jaw of the patient, the lower jaw of the patient is horizontally placed on the two arc-shaped supporting plates 9;

the connecting plates 7 are loosened, the two connecting plates 7 move inwards under the action of the elastic force of the springs 8, the two connecting plates 7 respectively drive the arc-shaped supporting plates 9 on the lower sides of the two connecting plates to move inwards, the distance between the two arc-shaped supporting plates 9 is gradually reduced, the lower jaw of a patient is fixed between the two arc-shaped supporting plates 9, then the height of the lower jaw of the patient is adjusted, when the height of the lower jaw of the patient is too low, the handle 13 is rotated from front to back, the handle 13 drives the rotating disc 12 to rotate from front to back, the rotating disc 12 drives the screw rod 11 to rotate from front to back on the two supporting plates 10, and the screw rod;

the two sliding blocks 2 drive the lower ends of the connecting rods 4 corresponding to the sliding blocks to swing inwards through the connecting blocks 3 respectively, the upper ends of the two connecting rods 4 start to move upwards simultaneously, the U-shaped rods 5 are driven to move upwards, the U-shaped rods 5 drive the sliding shafts 6 on the left side and the right side to move upwards simultaneously, the sliding shafts 6 drive the arc supporting plates 9 corresponding to the sliding shafts through the connecting plates 7 to move upwards, the two arc supporting plates 9 drive the lower jaws of patients to move upwards, the patients can be anesthetized when the lower jaws of the patients reach proper heights, when the lower jaws of the patients are too high, the heights of the lower jaws of the patients can be reduced only by rotating the handle 13 from back to front, and the patients can be anesthetized in a more comfortable.
