Firstly, a medical worker twists a knob to rotate, the knob rotates to drive a disc to rotate, the disc rotates to drive a color blind plate to rotate, when the color blind plate rotates to a proper position, the knob is stopped, the medical worker pulls a first pull block to move forwards, the first pull block moves forwards to drive a first movable rod to move forwards, the first movable rod moves forwards to drive a first fixed block to move forwards, the first fixed block moves forwards to drive a guide slide block to move backwards through a first pull wire, a first spring is stretched, the guide slide block moves backwards to drive a first rack to move backwards, the first rack moves backwards to drive a pinion to rotate backwards, the pinion rotates backwards to drive a circular plate to rotate backwards, the circular plate rotates to enable a color area to rotate, when the first movable rod moves forwards to the right side of a proper first guide hole, the first pull block is stopped to pull, a first L-shaped stop rod is pulled to swing forwards, a second spring is compressed, when first L type pin forward swing does not block first guide hole, can stimulate first draw the piece to move left and drive first movable rod and move left, when first movable rod moves left to first guide hole in, can loosen first L type pin, because of the effect of second spring, first L type pin swings backward and resumes to the normal position, loosen first draw the piece again, and then first L type pin blocks first movable rod, the doctor can appoint a look blind plate and let people look over, if people can see the colour of fretwork digit on the look blind plate, just explain not have the look blind disease, otherwise then coloured blind disease, so relapse, can carry out the test of multiple colour to people, need test other colours, can take out the look blind plate from the standing groove and change, it can to put into the standing groove with new look blind plate again. After all colors are tested, the first L-shaped stop lever can be pulled to swing forwards again to prevent the first guide hole from being blocked, the first pull block is pulled to move rightwards to drive the first movable rod to move rightwards to be separated from the first guide hole, the first pull block is loosened, the first rack moves forwards to drive the pinion to rotate forwards under the action of the first spring, the pinion rotates forwards to drive the circular plate to rotate forwards to return to the original position, and meanwhile, the first pull block moves backwards to return to the original position.
Firstly, medical personnel pulls the second pull block to move backwards, the second pull block moves backwards to drive the second movable rod to move backwards, the second movable rod moves backwards to drive the second fixed block to move backwards, the second fixed block moves backwards to drive the second rack to move forwards through the second pull wire, the third spring stretches, the second rack moves forwards to drive the big gear to rotate backwards, the big gear rotates backwards to drive the rotating shaft to rotate backwards, the rotating shaft rotates backwards to drive the disc to rotate backwards to drive the color blinding plate to rotate backwards, when the second movable rod moves backwards to the right side of the proper second guide hole, the second pull block is stopped to pull the second L-shaped stop rod to swing backwards, the fourth spring is compressed, the second L-shaped stop rod swings backwards without blocking the second guide hole, the second pull block can be pulled to move leftwards to drive the second movable rod to move leftwards, the second movable rod moves leftwards to the second guide hole, and the second L-shaped stop rod is loosened, due to the action of the fourth spring, the second L-shaped stop lever swings forwards to stop the second movable rod, and therefore color blindness testing can be started for people. After the color blindness test is finished, the second L-shaped stop lever can be pulled to swing backwards without stopping the second movable lever, the second pull block is pulled to move rightwards to drive the second movable lever to move rightwards to be separated from the second guide hole, the second L-shaped stop lever is loosened to restore to the original position, the second pull block is loosened, the second rack moves backwards to drive the large gear to rotate forwards under the action of the third spring, the color blindness plate is driven to rotate forwards to restore to the original position, and meanwhile, the second pull block is driven to move forwards to restore to the original position. Therefore, the medical staff can more conveniently rotate the color blind plate.
When the achromatopsia is required to be replaced, medical personnel can pull the pressing plate to move upwards, the fifth spring is compressed, the pressing plate moves upwards and does not contact with the achromatopsia plate, and the achromatopsia plate can be taken out to be replaced. After the color blindness plates of other colors are placed, the pressing plate is loosened, and under the action of the fifth spring, the pressing plate moves downwards to be in contact with the color blindness plates to fix the color blindness plates, so that color blindness tests can be started for people. Therefore, the color blind plate can be prevented from being thrown out of the placing groove when rotating.
When the medical staff rotates the color blindness board to a proper position, people can confirm the digital color on the color blindness board pointed by the pointer. After people's achromatopsia test was accomplished, and when needing to change the achromatopsia board, can stimulate the pointer upwards the swing and be vertical state, pull 7 types kelly reversals again, 7 types kelly reversals card is gone into in the draw-in groove, and 7 types kelly and draw-in groove cooperation are fixed the pointer, can begin to change the achromatopsia board. After the color blindness plate is replaced, the 7-type clamping rod can be pulled to swing upwards to be separated from the clamping groove, and then the pointer is pulled to swing downwards to be restored to the original position. Therefore, people can more clearly confirm the number color on the appointed color blind plate.
Compared with the prior art, the invention has the following advantages: according to the invention, the color blind plates with different colors are placed in the placing groove, the color blind plates can be rotated by twisting the knob, the regions with different colors can be matched with the color blind plates by pulling the first pulling block, so that the patient can confirm the colors, the color blind plates do not need to be lifted by medical personnel, the color blind plates are more convenient, time and labor are saved, the color blind plates can be more conveniently rotated by the medical personnel through the rotating device, and the color blind plates can be fixed under the action of the pressing plate, so that the color blind plates are prevented from being separated from the placing groove when rotating.

Therefore, the medical staff can more conveniently rotate the color blind plate 8.
When the achromatopsia needs to be replaced, the medical staff can pull the pressing plate 33 to move upwards, the fifth spring 34 is compressed, the pressing plate 33 moves upwards and does not contact with the achromatopsia plate 8, and the achromatopsia plate 8 can be taken out for replacement. After the color blindness plates 8 of other colors are placed, the pressing plate 33 is loosened, and due to the action of the fifth spring 34, the pressing plate 33 moves downwards to contact with the color blindness plates 8 to fix the color blindness plates, so that the color blindness test of people can be started. Thus, the color blind plate 8 can be prevented from being thrown out of the placing groove 7 during rotation.
When the medical staff rotates the color blindness plate 8 to the proper position, people can confirm the digital color on the color blindness plate 8 pointed by the pointer 37. After people's achromatopsia test is accomplished, and when needing to change the achromatopsia board 8, can stimulate pointer 37 and upwards swing and be vertical state, pull 7 type kelly 38 reversal again, 7 type kelly 38 reversal card is gone into in draw-in groove 36, 7 type kelly 38 and draw-in groove 36 cooperation are fixed pointer 37, can begin to change the achromatopsia board 8. After the color blindness plate 8 is replaced, the 7-type clamping rod 38 can be pulled to swing upwards to be separated from the clamping groove 36, and then the pointer 37 is pulled to swing downwards to be restored to the original position. In this way, the person can more clearly confirm the number color on the assigned color blind plate 8.
