The working principle of the invention is as follows: firstly, starting the device, at this time, the cylinder will make the detection control part 2 move upwards, and at the same time, the detection control part 2 will drive the detection part 3 and the bracket part 7 to move upwards, and in addition, the vertical rod 501 will move upwards, when the vertical rod 501 moves upwards, the driving tooth wall 503 on the end surface of the vertical rod 501 will drive the driven gear 403 to rotate, after the driven gear 403 rotates, the first conical gear 404 will be driven by the action of the connecting shaft to rotate synchronously, the first conical gear 404 will then drive the second conical gear 405 to rotate by the gear meshing action, the second conical gear 405 will drive the driving gear 406 to rotate by the action of the transmission device, the driving gear 406 will therefore drive the slider 402 to move, so that the slider 402 slides outwards in the supporting seat 1 to realize the extension of the seat, after the supporting leg 408 at the bottom end of the slider 402 moves to the outside of the supporting seat 1, the supporting leg 408 will rotate from the horizontal state to the vertical state under the action of the torsion spring shaft, therefore, the supporting of the suspended part of the stool is realized, the stability of the stool is ensured, and similarly, when the equipment is closed, the air cylinder moves downwards, the detection control part 2 and the detection part 3 reset at the moment, the vertical rod 501 also moves downwards, so that the driving gear 406 drives the slider 402 to move towards the inside of the supporting seat 1, the accommodation of the stool mechanism is realized, the occupied area is saved, after the supporting leg 408 moves to one side along with the slider to be in contact with the side wall of the supporting seat 1, the supporting leg 408 rotates to the horizontal state from the vertical state and moves to the inside of the supporting seat 1 under the extrusion effect, the automatic accommodation of the supporting leg 408 is realized, and the device is convenient and practical;

when the vertical rod 501 moves, the top plate 502 at the bottom end of the vertical rod 501 can extrude the power rod 603 to move upwards, so that the power rod 603 pushes the extrusion plug 602 to extrude gas in the cavity 601, and the gas moves into the gas hole 7051 through the gas pipe 604 and is blown to the inner wall of the detection limiting frame 704, so that residual dust is clear, and the use of the detection limiting frame 704 is ensured;

then, the patient places the face on the bracket body 701, in the process, the chin part is placed on the support part 702, the eyes cannot be immediately positioned in the detection limit frame 704, under the action of the gravity of the face of the patient, the chin part can enable the support part 702 to move downwards and drive the ejector rod 703 to extrude downwards, the ejector rod 703 can extrude the lower pressing plate 801 to move downwards, and the movement of the lower pressing plate 801 can enable the lower pressing plate 802 and the push rod 811 to move downwards;

after the pressing rod 802 is pressed downwards, the piston 803 can press the medicament in the extrusion cavity 804, the medicament in the extrusion cavity 804 can flow into the medicament cavity 7052 through the medicament tube 805 and is sprayed into the detection limit frame 704 under the action of the atomizing sprayer, so that the disinfection effect on the detection limit frame 704 is realized;

after the push rod 811 is pressed down, the rotating gear 810 is driven to rotate under the action of gear meshing, after the rotating gear 810 rotates, the moving rods 809 are driven to move upwards, so that the blocking columns 808 can be pulled into the feed port 807 to prevent blanking under the action of the two groups of moving rods 809, and meanwhile, a closed space is formed between the feed pipe 806 and the extrusion cavity 804, so that the extrusion sterilization operation of the piston 803 is assisted;

after the device automatically completes the disinfection step, an operator controls the electric push rod to enable the detection limiting frame 704 to slide on the outer wall of the bracket body 701 for fine adjustment until the detection limiting frame 704 is located at a position suitable for a patient, and finally, the patient positions eyes in the detection limiting frame 704 after disinfection and dust removal are completed to perform eye detection imaging;

after the patient leaves the supporting part 702, the pre-tightening spring resets, so that the push rod 703 drives the lower pressing plate 801 to reset, at this moment, the piston 803 resets under the effect of the lower pressing rod 802, the push rod 811 can drive the rotating gear 810 to rotate reversely when moving upwards, the rotating gear 810 capable of rotating reversely can make the movable rod 809 move downwards, and then two sets of movable rods 809 drive the blocking column 808 to leave from the feed inlet 807, so that the external medicament can be filled, and the medicament supplement of the medicament pipe 805 is realized.
