In the present embodiment, as shown in fig. 10 to 15, the upper part of the inclined surface of the power plate 81 is a vertical surface, and when the roller 823 rolls to the vertical surface, the roller 823 rolls on the vertical surface, and at this time, the translation plate 82 stops moving.

The working principle provided by the invention is that when a patient performs intraocular pressure measurement, firstly, the mounting plate 1 needs to be placed on a tabletop, then the knob 13 is rotated, when the knob 13 is rotated, the sucker 12 moves downwards in the mounting post 11, air at the bottom of the sucker 12 is discharged in the process of downwards moving the sucker 12, after the air at the bottom of the sucker 12 is discharged, the knob 13 is stopped rotating, at the moment, the mounting plate 1 is fixed on the tabletop, then, the patient needs to attach eyes to the auxiliary component 6, simultaneously needs to place a chin on the adjusting component 7, after the posture of the head of the patient is set, the forehead needs to be extruded and attached to the triggering component 5, at the moment, the auxiliary component 6 stretches the epithelium of the patient, the eyeball of the patient is exposed to the air, then the position of the slit lamp living microscope 2 needs to be moved by controlling the adjusting handle 21, the slit-lamp living microscope 2 is made to face the eye to be examined of the patient, finally, the measuring head 3 is pressed on the pupil of the patient by controlling the adjusting handle 21, when the measuring head 3 is pressed on the eyeball of the patient, the tonometer 31 is bent, the scale drum 32 calculates the ocular pressure of the eye of the patient, after the pressure on the eye of the patient is observed from the slit-lamp living microscope 2 to reach the proper strength, the adjusting handle 21 is stopped to be operated, the ocular pressure of the eye of the patient at the moment is displayed on the scale drum 32, when the patient is in the intraocular pressure examination, the chin is firstly required to be placed on the placing plate 72, the placing plate 72 is pressed, the eye of the patient can be attached on the auxiliary component 6, when the eye of the patient is just attached on the auxiliary component 6, the forehead is required to be abutted against the elastic plate 521, at the moment, because the patient is pressed on the elastic plate 521 through the forehead, when the piston rod 512 is pushed, the oil in the hydraulic cylinder 511 enters the oil storage chamber 54 through the hose 531, when the oil enters the oil storage chamber 54, the positioning head 541 is pushed, when the positioning head 541 moves, the positioning head 541 passes through the adjusting hole 711, at this time, since the positioning head 541 is positioned in the positioning hole 43 and the adjusting hole 711, the placing plate 72 is fixed on the fixed rod 4, the patient applies the weight of the head to the placing plate 72, the shaking of the head is avoided, the tonometric measurement can be performed more stably, when the patient finishes checking, only the head needs to be separated from the trigger assembly 5, when the patient leaves the head from the trigger assembly 5, the first spring 514 compressed in the hydraulic cylinder 511 stretches and pushes the piston rod 512 to move reversely, when the piston rod 512 moves reversely, the oil in the oil storage chamber 54 is extracted through the hose 531, when the oil in the oil reservoir 54 is pumped out, the positioning head 541 is contracted and leaves the adjustment hole 711, and when the positioning head 541 leaves the adjustment hole 711, the compressed spring expansion rod 721 is extended and pushes the placement plate 72 to rise, so that the placement plate 72 is restored to its original position, when the patient places the eyes on the auxiliary assembly 6, the patient is first required to close the eyes and paste the eyelid on the silica gel plate 63, the head of the patient presses and sticks on the elastic plate 521 of the supporting case 52, the patient's eyes press on the silica gel plate 63, thereby pressing the third spring 631, and also pushing the piston rod 512, when the piston rod 512 is pushed, the trigger plate 513 is moved, when the trigger plate 513 is moved, the top of the lifting column 62 loses pressure, the compressed second spring 621 at the bottom of the lifting column 62 is extended, and the lifting column 62 is lifted, the inclined surface at the top of the lifting column 62 can be always clung to the inclined surface at the bottom of the trigger plate 513, when the lifting column 62 is lifted, the auxiliary rod 64 is clung to the silica gel plate 63, because the silica gel plate 63 is clung to the upper eyelid of a patient under the action of the third spring 631, when the silica gel plate 63 is lifted, the upper eyelid of the patient is upwards moved, the eyeballs of the patient are exposed to the air, after the position of the placing plate 72 is fixed, the silica gel plate 63 stops moving, because the friction force between the silica gel plate 63 and the upper eyelid is larger, the silica gel plate 63 fixes the position of the upper eyelid of the patient at the moment, the patient can keep the open state of eyes, the situation that the patient blinks frequently in the process of performing intraocular pressure examination is avoided, when the head of the patient leaves the trigger assembly 5, the piston rod 512 is pushed by the first spring 514, thereby resetting the trigger plate 513, in the process of resetting the trigger plate 513, the inclined plane of the lower Fang Shengjiang column 62 is extruded to enable the lifting column 62 to descend and enable the silica gel plate 63 to reset at the same time, then the moving sleeve 61 is required to be pushed to enable the silica gel plate 63 to be located on the other side of the bottom of the supporting box 52, the eye pressure of a patient is convenient to check, when the patient places a chin on the placing plate 72, the placing plate 72 can descend with the adjusting rod 71, in the process of descending of the adjusting rod 71, the power plate 81 fixedly connected to the adjusting rod 71 descends synchronously, in the process of descending of the power plate 81, the roller 823 located on the inclined plane of the bottom of the power plate 81 is pushed, the roller 823 rolls on the inclined plane, at the moment, the power plate 81 pushes the translation plate 82 to move, the balance plate 822 horizontally moves on the supporting box 52 when the translation plate 82 moves, the translation plate 82 horizontally moves under the action of the balance plate 822, when the translation plate 82 moves horizontally, on the one hand, the push plate 821 on the translation plate 82 pushes the trigger rod 844, when the trigger rod 844 is pushed, the trigger rod 844 drives the rotating sleeve 842 to rotate on the auxiliary rod 64, when the rotating sleeve 842 rotates, the alcohol cotton sheet 841 on the inner side of the sterilizing plate 84 is attached to the surface of the silica gel plate 63 to move, so that the surface of the silica gel plate 63 is cleaned and sterilized, on the other hand, when the translation plate 82 moves, the alcohol cotton sheet 841 moves to the inside of the limit cylinder 83 and presses the fifth spring 824, when a patient determines the position of the head and locks the placing plate 72, at the moment, the alcohol cotton sheet 841 finishes sterilizing the silica gel plate 63, meanwhile, the sterilizing plate 84 rotates to one side of the silica gel plate 63 and does not obstruct the intraocular pressure checking of the patient, when the intraocular pressure checking of the patient is finished leaving the placing plate 72, the trigger plate 513 is reset, the positioning head 541 contracts, the placing plate 72 is lifted under the action of the spring telescopic rod 721, at the moment, the adjusting rod 71 is lifted, on the power plate 81, in the process, the fifth spring 824 drives the translation plate 82 to reset, so that the roller 843 always resets, and the rotating plate 823 can rotate on the opposite side of the rotating plate 82, and the rotating plate 843 is turned reversely, and the rotating plate 82, and the rotating plate is opposite to the rotating plate 843, and when the rotating plate is opposite to the rotating plate is attached to the rotating plate 63.
