When the medical staff needs to carry out the achromatopsia test, the medical staff can place the invention on the table top, the medical staff respectively places primary color monochromatic patterns such as red, green and blue on the placing groove of the lower rotating disc, then places the placing pattern in the transparent placing frame, then firstly the test staff observes the primary color in the placing groove through the first fan-shaped hole from the opening, after the test staff observes a color, the medical staff rotates the left rotating shaft, the left rotating shaft drives the gear to rotate, the gear drives the gear ring to rotate, and then the lower rotating disc is driven to rotate, so that the primary color monochromatic patterns rotate along with the primary color patterns, thereby preliminarily judging whether the test staff has the achromatopsia condition, in order to further determine the result, the medical staff rotates the right rotating shaft clockwise, the right rotating shaft drives the lower rotating rod to rotate clockwise, the lower rotating rod pushes the stop block to rotate anticlockwise, the stop block drives the upper rotating disc to, the tester can observe the numbers or patterns on the placing picture, if the tester can clearly identify the numbers or patterns, the tester can judge that the tester has no color blindness, when the tester can not identify the numbers or patterns, the tester proves that the tester has the color blindness or color weakness phenomenon, after the test is finished, the medical worker can put the test device back to the original position, the first spring has the function that the medical worker rotates the right rotating shaft anticlockwise, when the lower rotating shaft rotates anticlockwise, the stop block which is pushed down by the lower rotating shaft is convenient to reset, because the stop block is connected in a rotating way and can only rotate in a single direction, when the lower rotating shaft rotates clockwise, the upper rotating disc can be driven to rotate by pushing the stop block, when the lower rotating shaft rotates anticlockwise, the stop block can be pushed down, the upper rotating disc can not rotate along with the lower rotating shaft, the tester can only observe through the opening, the observation area is reduced, and the reminding probability of other people is reduced, meanwhile, medical staff can place the placement chart randomly when placing the placement chart, randomness is improved, and a test result is more accurate.

When medical personnel need place or change and place the picture, medical personnel extract the inserted bar from first through-hole and second through-hole earlier, place the platform and outwards pop out under the spring force effect of second spring, it drives the outside slip of guide arm to place the platform, then medical personnel can be with placing the picture and put to big recess or change and place the picture, after medical personnel placed or change and finish, medical personnel inwards promote and place the platform, and then compress the second spring, it drives the inside slip of guide arm to place the platform, after placing the platform and remove to target in place, medical personnel insert the inserted bar in first through-hole and second through-hole again, thereby to place the rigidity of platform, can prevent like this that medical personnel from rotating right pivot, the position of placing the picture takes place to remove and makes the tester observe inconveniently.

It is more to place the pattern on the picture, in order to reduce the interference of other patterns to the tester, baffle and instruction arrow point have been set up, when needs test tester, medical personnel anticlockwise rotation right pivot, the right pivot drives upper rotating rod anticlockwise rotation, upper rotating rod promotes the rail clockwise rotation, the rail drives square groove clockwise rotation, and then drive baffle and instruction arrow point clockwise rotation, the tester can only observe the pattern that instructs the arrow point to indicate the region through the second fan-shaped hole, other regional patterns are sheltered from by the baffle and can't be seen, can reduce other patterns and to tester's interference like this, the effect of fifth spring is when medical personnel clockwise rotation right pivot, support for the rail provides, make the rail can rotate, and can not be along with right pivot clockwise rotation.

In order to prevent that the carousel from taking place to rotate when medical personnel anticlockwise rotation right pivot, and then drive and place the picture and take place the skew, bring inconvenience and set up first pin to test personnel's observation, when medical personnel clockwise rotation right pivot, the carousel anticlockwise rotates thereupon, because the inside one side of little recess is the tilt state, so, first pin can roll-off in the little recess, the third spring is stretched, along with the rotation of right pivot, first pin can roll-off under the spring force effect of third spring in adjacent little recess, the third spring resets, when medical personnel anticlockwise rotation right pivot, because the inside another side of little recess is vertical state, first pin can withstand little recess bottom, thereby prevent the carousel rotation, it also can not take place the skew just to place the picture.

In order to prevent that the baffle from taking place to rotate when medical personnel rotate right pivot clockwise, and then it takes place the skew to drive the instruction arrow point, bring inconvenience and set up the second pin to testing personnel's observation, the one side roll-off that the second pin can follow the wall inslot slope when medical personnel rotate right pivot anticlockwise, the fourth spring is compressed, along with the rotation of right pivot, the second pin can slide into adjacent wall inslot, the fourth spring resets, when medical personnel rotate right pivot clockwise, the one side that the second pin withstood the wall inslot and is not inclined, thereby prevent that the baffle from rotating.

When the medical instrument is used for testing, a tester can only observe through the opening on the right side of the shell and the first fan-shaped hole in the supporting plate, and can only observe the pattern in the area indicated by the indication arrow, and the patterns in other areas are shielded by the baffle plate and cannot be seen, so that the reminding probability of other people is reduced, medical workers can randomly place the placement chart when placing the placement chart, the randomness is improved, the testing result is more accurate, the medical workers can adjust the positions of the primary colors and the patterns by rotating the left rotating shaft and the right rotating shaft, the testing difficulty is improved, and the testing result is more accurate.
