The eyelid opening device comprises an upper eyelid poking component 4, a lower eyelid poking component 5 and an elastic reset component 8 connected between the upper eyelid poking component 4 and the lower eyelid poking component 5, wherein the elastic reset component 8 is a spring or a shrapnel. The patient puts the eyes in the space between the upper eyelid toggle part 4 and the lower eyelid toggle part 5, the upper eyelid is tightly attached to the upper eyelid toggle part 4, and the lower eyelid is tightly attached to the lower eyelid toggle part 5; the driving mechanism can drive the upper eyelid toggle component 4 and the lower eyelid toggle component 5 to move relatively, thereby driving the upper eyelid and the lower eyelid to be spread.

As shown in fig. 10, specifically, the upper eyelid toggle component 4 and the lower eyelid toggle component 5 both include a connecting rod 42 connected to the driving mechanism, an arc-shaped opening block 41 attached to the eyelid, and the connecting rod 42 and the arc-shaped opening block 41 are detachably connected to each other in a rotatable manner, the surface of the arc-shaped opening block 41 attached to the eyelid is made into a rough surface or wrapped with gauze, during testing, the upper and lower eyelid skins of the face are abutted against the arc-shaped opening block 41, and the upper and lower eyelids of the eyes are opened by friction force. Connecting rod 42 and arc strut and to dismantle the rotation between piece 41 and be connected, the arc struts and fastens through second threaded fastener 43 between piece 41 and the connecting rod 42, when rotatory second threaded fastener 43, can strut two grip blocks of piece 41 hinged end to the arc and extrude and be close to, thereby strut piece 41 and connecting rod 42 turned angle with the arc and adjust and fasten after well, second threaded fastener 43 can also be the screw bolt and nut cooperation, the bolt penetrates after the arc struts piece 41 and connecting rod 42, cooperate the nut again and screw the lock die. The arc-shaped opening block 41 and the connecting rod 42 can be adjusted in rotation angle, so that the fine adjustment of facial form and facial form of more crowds can be adapted, the flexible adjustment of opening the eyelid can be more adapted, and the comfort of opening the eyelid can be improved. The number of times of detection failure caused by eye blinking of a patient to be detected due to insufficient self-control capability is reduced, the condition that the patient can be measured in place at one time can be guaranteed approximately, the range of opening naked eyes is large, the requirement of instruments is met, and therefore the accuracy of tonometer detection is achieved.

One end of an eyelid toggle component 4 and one end of a lower eyelid toggle component 5 are vertically and slidably connected with a support frame 1, a head support plate 2 drives the upper eyelid toggle component 4 and the lower eyelid toggle component 5 to move together through a driving mechanism, the upper eyelid toggle component 4 and the lower eyelid toggle component 5 can be ensured to be close to each other or be far away from each other, and the driving mechanism comprises a fixed pulley 3 connected with the upper end of the support frame 1, a first tension component 6 and a second tension component 7 which are wound around the fixed pulley 3; two ends of the first tension component 6 are respectively connected to the upper end of the upper eyelid toggle component 4 and the insertion rod 22 at the end part of the head support plate 2, the insertion rod 22 is slidably connected in the strip-shaped guide rail 10 longitudinally arranged on the support frame 1, the strip-shaped guide rail 10 is a strip-shaped plate, a rectangular through hole is longitudinally arranged on the strip-shaped plate, and the insertion rod 22 can slide in the rectangular through hole; the two ends of the second pulling force component 6 are respectively connected to the lower end of the lower eyelid toggle component 5 and the insertion rod 22 at the end of the head support plate 2, so that the upper eyelid toggle component 4 and the lower eyelid toggle component 5 can be ensured to be close to or away from each other.

The first tension component 6 and the second tension component 7 are both steel wire ropes and are hidden in an inner cavity of the support frame 1. Go up the eyelid and stir 4 one ends of part and 5 one ends of part are all connected with the cube slider to the eyelid down, and cube slider sliding connection is in the bar spout that support frame 1 inner wall was seted up, and the bar spout is seted up on support frame 1 is longitudinal, guarantees that the cube slider can be pulled by wire rope, along vertical direction up-and-down motion. The both ends of first pulling force part 6 are connected respectively on 4 upper ends of upper eyelid toggle part and 2 tip inserted bars 22 of head backup pad, and inserted bar 22 sets up the cuboid structure of growing up, and the bar groove of bar guide rail 10 also sets up the cuboid bar groove structure that matches with inserted bar 22 to guarantee that inserted bar 22 violently freely slides from top to bottom in bar guide rail 10. The structure of the invention controls the opening range of eyes by self-sensing, and the head support table 2 is properly pressed according to self-finding, thus being more suitable for the comfort of human body and being convenient to operate.

The ophthalmology test bench designed by the invention is applied to the existing tonometer, and the tonometer is provided, as shown in fig. 3 and 4, the structure mainly comprises the existing tonometer body 9 and the air pressure mouthpiece 91 installed on the tonometer body 9, the existing ophthalmology test bench is only replaced by the improved ophthalmology test bench, and the air pressure mouthpiece 91 corresponds to the eyes of a patient to be tested during testing. However, the present invention is not limited to tonometers and may be used with other instrumentation devices where eye items need to be measured to assist in opening the eye.

The working principle is as follows: the head of a person is placed on the head support platform 2, the chin is moved to the chin support platform 21, the eyes are placed in a space between the upper eyelid poking component 4 and the lower eyelid poking component 5, the upper eyelid just props against the upper eyelid poking component 4 at the moment, and the lower eyelid props against the lower eyelid poking component 5. Then the human head presses down the generating mechanism to link according to the feeling with force: the head supporting table 2 moves downwards, the first steel wire 6 is pulled to stir the upper eyelid part 4 to move upwards to drive the upper eyelid to move upwards, and meanwhile, the second steel wire 7 is pulled to stir the lower eyelid part 7 to move downwards to prop open eyes.
