In order to facilitate the medical staff to limit the fixed plate 5, the rotating shaft 6 is coaxially provided with a ratchet wheel 10 positioned above the rotating wheel 7, the front end of the supporting plate 2 is hinged with a pawl 11 which is vertically arranged and the lower end of the supporting plate can be clamped between two adjacent teeth of the ratchet wheel 10, and the pawl 11 is connected with the supporting plate 2 through a torsion spring 12.

In order to facilitate the resetting of the fixing plate 5, the rear end of the supporting plate 2 is provided with a protective shell, the protective shell is connected with two left and right opposite connecting plates 13 in a sliding manner, the clamping plates 4 are positioned between the two connecting plates 13, the opposite ends of the two connecting plates 13 are respectively connected with the supporting plate 2 through left and right compression springs 14, and the opposite ends of the two connecting plates 13 are respectively contacted with the clamping plates 4 on the corresponding sides.

In order to facilitate the height adjustment of the support plate 2, the right end of the support plate 2 is provided with a plurality of limiting holes 15 which are distributed along the vertical direction and are in the left-right axial direction, the support plate 2 is connected with a limiting rod 16 which is in the left-right axial direction and the left end of which can be inserted into the limiting holes 15 in a sliding manner, and the limiting rod 16 is connected with the support plate 2 through a spring 17.

In order to facilitate the fixing of the medical staff to the U-shaped frame 1, the lower end of the U-shaped frame 1 is provided with a fixing frame 18 with an opening facing forwards and in the left-right direction, the fixing frame 18 is in threaded connection with an upper axial screw rod 19 and a lower axial screw rod 19, and the upper end of the screw rod 19 penetrates through the fixing frame 18 and is provided with a clamping plate 20 in the left-right direction.

When the slit lamp operating table is used, a medical worker clamps a fixing frame 18 on the slit lamp operating table, the medical worker rotates a screw 19 anticlockwise at the moment, the screw 19 drives a clamping plate 20 to move upwards, after the slit lamp operating table moves for a certain distance, the clamping plate 20 is in contact with the operating table, the fixing frame 18 and the operating table are fixed relatively, the medical worker guides the chin of a patient to be tightly attached to a supporting plate 2 and located between two clamping plates 4 at the moment, a limiting rod 16 is pulled rightwards, the spring 17 is stretched rightwards when the limiting rod 16 moves rightwards, the spring 17 has leftwards elastic force, and after the slit lamp operating table is pulled for a certain distance, the left end of the limiting rod 16 is far away from the matching of a limiting hole 15, so that the limiting of the supporting plate 2 is relieved;

at the moment, after the medical staff moves the supporting plate 2 upwards or downwards for a certain distance, the eye of the patient is equal to the height of the slit lamp, at the moment, the medical staff loosens the limiting rod 16, after the limiting rod 16 moves leftwards for a certain distance due to the left elasticity of the spring 17, the left end of the limiting rod 16 is inserted into the limiting hole 15 again to limit the supporting plate 2, at the moment, the medical staff rotates the rotating shaft 6 anticlockwise, the rotating shaft 6 drives the rotating wheel 7 to rotate anticlockwise, the rotating wheel 7 rotates and simultaneously presses the lower ends of the clamping plates 4 on the corresponding sides, so that the lower ends of the two clamping plates 4 swing back to each other, the upper ends of the two clamping plates 4 are driven to swing oppositely, the upper ends of the two clamping plates 4 drive the fixing plates 5 on the corresponding sides to swing oppositely, after swinging for a certain angle, the fixing plates 5 are contacted with the head of the patient, and the head of the patient is fixed;

when the lower ends of the two clamping plates 4 swing back to back, the two compression springs 14 are extruded back to back, so that the two compression springs 14 have opposite elasticity, the rotating shaft 6 drives the ratchet gear 10 to rotate anticlockwise while rotating anticlockwise, the ratchet gear 10 extrudes the pawl 11 forwards while rotating anticlockwise, the pawl 11 drives the torsion spring 12 to rotate clockwise, so that the torsion spring 12 has anticlockwise torsion, the ratchet gear 10 continues to rotate anticlockwise, the pawl 11 swings forwards until the lower end is far away from between two adjacent teeth of the ratchet gear 10, the limit on the rotating shaft 6 is released, after the medical staff stops rotating the rotating shaft 6, the pawl 11 swings backwards due to the anticlockwise torsion of the torsion spring 12 until the lower end is clamped between two adjacent teeth of the ratchet gear 10 again, the limit on the shaft is aligned, the head of a patient is prevented from shaking in the checking process, and the checking result is influenced;

after the examination is finished, the medical staff swings the pawl 11 forwards for a certain angle, the lower end of the pawl 11 is far away from the matching between two adjacent teeth of the ratchet gear 10, the limit on the rotating shaft 6 is released, at the moment, the lower ends of the two clamping plates 4 swing oppositely due to the elasticity of the pressure spring 14, so that the upper ends of the two clamping plates 4 swing oppositely, the upper ends of the two clamping plates 4 drive the fixing plates 5 on the corresponding sides to swing oppositely, and after the pawl swings for a certain angle, the fixing plates 5 are far away from the head of the infant and the head is released from being fixed;

the runner 7 of its corresponding side is extruded in the relative wobbling of lower extreme of two splint 4 to drive pivot 6 clockwise turning, pivot 6 drive ratchet gear 10 clockwise turning, treat that fixed plate 5 gets back to initial position after, medical personnel loosen pawl 11, pawl 11 lower extreme card is gone into again between the two adjacent teeth of ratchet gear 10, realizes the spacing to fixed plate 5, and medical personnel guides the infant chin this moment and keeps away from backup pad 2 can.

When the utility model is used, when the rotating shaft 6 is rotated for a certain angle and the two fixed plates 5 are contacted, the connecting line between the centers of the circles of the two rotating wheels 7 is not changed into the horizontal direction.
