The working principle is as follows: firstly, the fixing through hole 7 is internally provided with screw threads, when medical staff needs to examine a patient through the distraction device main body 1, the medical staff needs to put the eyelid opener 2 at one side of the distraction device main body 1 under the eyelid of the patient, when the eyelid opener 2 is placed, the medical staff needs to rotate the movable handle 5 by manual clockwise movement, so that the movable handle 5 drives the stud 6 to rotate clockwise, when the stud 6 rotates clockwise, the stud 6 can move forwards through the screw threads in the fixing through hole 7, when the stud 6 moves forwards through the fixing through hole 7, the stud 6 can push the pushing block 8 to move forwards, when the pushing block 8 moves forwards, the pushing block 8 can push the pushing arm 9 to open towards two ends, so that the pushing arm 9 pushes the linkage arm 3 to open towards two ends, when the linkage arm 3 opens, the eyelid opener 2 at one side of the linkage arm 3 can be distracted, thereby the medical staff can quickly achieve the purpose of opening the eyelids of the patient.

Then, when the stud 6 pushes the pushing block 8 forward, the pushing block 8 pushes the pushing arms 9 on both sides while moving forward again, when the pushing arms 9 are pushed by the pushing block 8, the pushing arms 9 can convert the forward pushing force of the pushing block 8 into the force toward both ends through the bearing rod 802 and the movable groove 803 inside the pushing block 8, so that the pushing arms 9 are spread toward both ends, thereby achieving the effect of spreading the linkage arm 3, when the linkage arm 3 is spread, the linkage arm 3 can drive the eyelid opener 2 on one side to be spread simultaneously, thereby achieving the effect of helping medical staff to spread the eyelids of the patient, the bearing rod 802 can convert the pushing force from the pushing block 8 into the force driving the pushing arms 9 to be spread toward both ends, thereby making the work efficiency of the spreading device body 1 higher.

Then, when the medical staff uses the distraction device main body 1 to complete, the medical staff needs to put the magnifier 15 back to the previous position at the top of the fixing plate 4 through the telescopic arm 17, when the medical staff puts the magnifier 15 back to the top of the fixing plate 4 through the telescopic arm 17, the medical staff needs to put the clamping column at the bottom of the magnifier 15 into the limiting hole 16 at the top of the fixing plate 4, after the medical staff puts the clamping column at the bottom of the magnifier 15 into the limiting hole 16, the magnifier 15 is fixed by the limiting hole 16, so that the magnifier 15 can not fall off from the distraction device main body 1 when the distraction device main body 1 moves or turns, the magnifier 15 can be stably fixed on the fixing plate 4 through the limiting hole 16, thereby achieving the effect of protecting the magnifier 15, and embodying the protection of the device.

Next, two eyelid openers 2 are arranged, when the medical staff uses the distraction device body 1 for many times, the eyelid openers 2 on one side of the distraction device body 1 can be worn due to being cleaned and disinfected for many times, when the eyelid openers 2 on one side of the distraction device body 1 are worn, the distraction device body 1 can not be used any more, because the worn eyelid openers 2 can damage eyes of a patient when being used, the worn eyelid openers 2 need to be detached at the moment, when the medical staff replaces the eyelid openers 2, the medical staff needs to manually rotate the eyelid opener fixing head 10 counterclockwise to ensure that the convex column 11 is screwed out from the inside of the groove 13, when the convex column 11 is completely separated from the inside of the groove 13, the medical staff can replace a new eyelid opener 2, when changing, medical staff need aim at recess 13 with projection 11, after aiming at, in the recess 13 of screwing projection 11 that is slow again, when projection 11 screws in recess 13, new eyelid opener 2 has just been changed and has been accomplished, thereby make medical staff can continue to use strutting device main part 1 to carry out work, make when eyelid opener 2 damages need not throw away strutting device main part 1 and then eyelid opener 2 that damages together through such setting, thereby make the great extension of life of strutting device main part 1, the practicality of the device has been embodied.

Finally, when the medical staff inspects the eyes of the patient through the distraction device main body 1, the medical staff needs to insert the eyelid mouth gag 2 into the upper and lower eyelid skin positions of the eyes of the patient firstly, after the eyelid mouth gag is placed, the medical staff distracts the eyelid mouth gag 2 through the timely rotating movable handle 5, after the medical staff thinks that the eyelids of the patient are already propped to a proper position, the medical staff can stop rotating the movable handle 5, when the eyelids of the eyes of the patient are propped, the medical staff can inspect the eyes of the patient, when the medical staff inspects the eyes unclearly, the medical staff can pull out the magnifier 15 from the limiting hole 16 by holding the magnifier handle 20 with hands, after the magnifier 15 is pulled out, the medical staff lifts the magnifier 15 upwards to enable the telescopic arms 17 at two ends of the bottom of the magnifier 15 to extend upwards, when the telescopic arms 17 extend upwards to a certain position, medical staff just can drive flexible arm 17 toward one side with magnifying glass 15 and remove, when flexible arm 17 moved toward one side, movable rod 19 of flexible arm 17 bottom will carry out corresponding rotation through bearing 18, thereby make magnifying glass 15 remove patient's eye top, later medical staff just can go to group's patient through magnifying glass 15 and inspect, thereby make medical staff more clear of inspection when group's patient inspection eye, the high efficiency of the device has been embodied, this is exactly this eyelid struts the theory of operation of device for ophthalmic examination.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
