People with refractive errors will have lower naked eye vision than normal, but after wearing glasses, it can be corrected to normal vision 1.0. Vision testing is the primary reference value for eye examinations and an important criterion for evaluating the quality of human eyes. It can also provide effective auxiliary diagnosis for other eye diseases and disease stages. Usually, the head needs to be fixed when testing vision.

[0032] When in use, the motor 4 is started to control the rotation of the bidirectional threaded rod 5. The rotation of the bidirectional threaded rod 5 can make the two moving blocks 7 slide relatively along the two adjusting transverse grooves 6, and the two L-shaped moving plates 8 can be moved to the opposite sides by the movement of the two moving blocks 7 until the two rubber side plates 10 are in contact with the face of the tester and then closed. The two clamping plates 9 and the two rubber side plates 10 can keep the head of the tester in a relatively stable position during the test, reducing the influence of the head shaking on the accuracy of the test result. After use, the two L-shaped moving plates 8 and the two rubber side plates 10 can be moved to the inside of the two storage boxes 1 for storage by starting the motor 4 to reversely control the rotation of the bidirectional threaded rod 5, thereby increasing the service life of the two rubber side plates 10 and improving the durability of the device.

There is an arc groove 32, the upper surface of the two L-shaped movable plates 8 and the rear surface of the two clamping plates 9 are rotatably connected with an adjusting cylinder 33 through a rotating shaft, the output ends of the two adjusting cylinders 33 are respectively rotatably connected with the opposite sides of the two clamping plates 9 through a rotating shaft, the lower surface of the upper pressure plate 19 is fixedly connected with a buffer box 34, the interior of the buffer box 34 is slidably connected with a sliding plate 35, the lower surface of the sliding plate 35 is fixedly connected with a plurality of connecting rods 36, the bottom ends of the plurality of connecting rods 36 all extend to the bottom of the buffer box 34, and are fixedly connected with an arc top plate 37, the upper surface of the sliding plate 35 and the inner upper surface of the buffer box 34 are fixedly connected with a plurality of springs 38;

[0034] After the head of the inspector is initially fixed by the two rubber side plates 10, the motor 2 15 is started to control the rotation of the bidirectional threaded rod 2 17. The rotation of the bidirectional threaded rod 2 17 can make the two sliding blocks 18 slide relatively inside the sliding vertical groove 16, and the lower support plate 2 and the upper pressing plate 19 can be moved to the opposite sides by the movement of the two sliding blocks 18, so as to shorten the distance between the lower support plate 2 and the upper pressing plate 19. When the upper pressing plate 19 moves to a certain position, the arc top plate 37 will be squeezed by the head of the inspector, and the arc top plate 37 drives the sliding plate 35 through the multiple connecting rods 36. By sliding upward inside the buffer box 34 and compressing the multiple springs 38, the dynamic buffering adjustment can be continuously performed according to the slight movement or pressure change of the head of the inspected person when fixing the head of the inspected person, ensuring that the head is always in a stable and appropriate support and fixation state, ensuring the accuracy of the test result, and at the same time, the arc groove 32 can provide an effective placement point for the chin of the inspected person, and the two adjusting cylinders 33 can adjust the angles of the two rubber side panels 10, so that the heads of people with different head circumferences can be preliminarily fixed, thereby increasing the flexibility of the device.

A guide rod 47 is symmetrically fixedly connected to the lower surface of the upper extension plate 46, and the outer side walls of the two guide rods 47 are respectively slidably connected to the two extension plates 46 located below the connecting plate 45;

[0038] By setting up two guide rods 47, the lower support plate 2 and the upper pressure plate 19 can be moved relative to each other to fix the head of the inspector, thereby ensuring that the lower support plate 2 and the upper pressure plate 19 maintain vertical movement, thereby achieving accurate positioning and stable support effect for the inspector's head.

[0039] like Figure 1 , Figure 3 and Figure 6 As shown, a liquid storage tank 20 is provided on the upper surface of the upper pressing plate 19, and L-shaped delivery pipes 21 are fixedly connected to the left and right sides of the liquid storage tank 20, and electromagnetic valves 48 are provided on the outer walls of the two L-shaped delivery pipes 21. The ends of the two L-shaped delivery pipes 21 away from the liquid storage tank 20 extend to the bottom of the upper pressing plate 19, and are rotatably connected to the infusion hoses 22. The interiors of the two storage boxes 1 are integrally formed with extrusion chambers 23, and the interiors of the two extrusion chambers 23 are slidably connected with piston plates 1 24, and the opposite sides of the two piston plates 1 24 are fixedly connected with resistance blocks 25, and the opposite sides of the two resistance blocks 25 are respectively in contact with the opposite sides of the two L-shaped movable plates 8, and the opposite sides of the two piston plates 1 24 are respectively fixed with the interiors of the two extrusion chambers 23.

[0040] When the device is used, the two L-shaped movable plates 8 move to move the two rubber side plates 10 to the inside of the two storage boxes 1. The two abutment blocks 25 are squeezed by the two L-shaped movable plates 8 to drive the two piston plates 1 24 to slide in opposite directions inside the two extrusion chambers 23, and at the same time stretch the multiple springs 1 26. The two piston plates 1 24 slide to transport the airflow inside the two extrusion chambers 23 to the inside of the two cleaning boxes 3 through the two air delivery hoses 27 provided, so that the two piston plates 28 can slide forward inside the two cleaning boxes 3, and the two rotating tubes 30 can be respectively extended to the inside of the two storage boxes 1 through the two protruding circular holes 29, and the storage can be opened by opening the solenoid valves 48 outside the two L-shaped delivery pipes 21.

That is, when the two rubber side panels 10 are retracted into the inside of the two storage boxes 1, the outside of the two rubber side panels 10 is automatically disinfected, thereby preventing the spread of bacteria and viruses and increasing the safety of the device. When the two L-shaped movable plates 8 need to be used, the two rotating tubes 30 can be retracted into the inside of the two cleaning boxes 3 through the rebound of the multiple springs 26, so that the two L-shaped movable plates 8 can drive the two rubber side panels 10 to slide out, ready for the next disinfection.

[0042] When the two rotating tubes 30 extend into the interior of the two storage boxes 1, the two electric push rods 43 can drive the two rack plates 44 to move up and down according to preset program instructions, thereby changing the angles of the two rotating tubes 30, so that the disinfecting alcohol can be accurately sprayed to the outside of the two rubber side panels 10, thereby achieving an all-round disinfection effect on the two rubber side panels 10, improving the disinfection quality, reducing sanitary dead corners, and further increasing the safety of the device.
